The U.S. Food and Drug Administration (FDA) has not approved any drug for the direct treatment of stuttering. However, the effectiveness of pharmacological agents, such as benzodiazepines, anticonvulsants, antidepressants, antipsychotic and antihypertensive medications, and dopamine antagonists in the treatment of stuttering has been evaluated in studies involving both adults and children.

A comprehensive review of pharmacological treatments of stuttering in 2006 concluded that few of the drug trials were methodologically sound. Of those that were, only one, not unflawed study, showed a reduction in the frequency of stuttering to less than 5% of words spoken. In addition, potentially serious side effects of pharmacological treatments were noted, such as weight gain, sexual dysfunctions and the potential for blood pressure increases. There is one new drug studied especially for stuttering named pagoclone, which was found to be well-tolerated "with only minor side-effects of headache and fatigue reported in a minority of those treated".

Several treatment initiatives, for example the McGuire programme, and the Starfish Project advocate diaphragmatic breathing (or "costal breathing") as a means by which stuttering can be controlled.

Some practitioners believe there would be evidence indicating anxiolytics to be helpful in treating children and adults with selective mutism, to decrease anxiety levels and thereby speed the process of therapy. Use of medication may end after nine to twelve months, once the person has learned skills to cope with anxiety and has become more comfortable in social situations. Medication is more often used for older children, teenagers, and adults whose anxiety has led to depression and other problems.

Medication, when used, should never be considered the entire treatment for a person with selective mutism. While on medication, the person should be in therapy to help them learn how to handle anxiety and prepare them for life without medication.

Antidepressants have been used in addition to self-modeling and mystery motivation to aid in the learning process.

Spacing is important to integrate, especially with self-modeling. Repeated and spaced out use of interventions is shown to be the most helpful long-term for learning. Viewing videotapes of self-modeling should be shown over a spaced out period of time of approximately 6 weeks.

Treatment depends on the specific cause if known as well as the extent, type and configuration of the hearing loss. Most hearing loss, that resulting from age and noise, is progressive and irreversible, and there are currently no approved or recommended treatments; management is by hearing aid. A few specific kinds of hearing loss are amenable to surgical treatment. In other cases, treatment is addressed to underlying pathologies, but any hearing loss incurred may be permanent.

There are a number of devices that can improve hearing in those who are deaf or hard of hearing or allow people with these conditions to manage better in their lives.

Braille equipment includes a variety of multipurpose devices, which enhance access to distance communication. Some can be used as stand-alone devices connected via Wi-Fi, while others are paired with a mobile device to provide tactile access to e-mail, text messaging, and other modern communication resources. To receive Braille equipment, an eligible consumer must be proficient in Braille and must have access to the Internet or cellular service.

The Telebraille does not have a computer communications modem but does have a TTY (TDD) modem. It was designed as a TTY for deaf-blind people and is also useful for face-to-face conversation. It has two components. The sighted component is a modified SuperCom TTY device. It has a qwerty keyboard and a single-line LED display. The display is regular size and is not particularly suited to people with low vision. The SuperCom TTY can be connected directly to the telephone line using a conventional telephone jack or the telephone receiver can be coupled to the SuperCom on a cradle on top of the device. Text flows past the display in a continuous stream, like tickertape. The SuperCom is connected to the Braille portion of the device by a cable that is about two feet long. The Braille display is about 15 characters in width, although there is a knockout to allow additional characters to be installed, at considerable additional cost. The Telebraille is able to communicate in ASCII mode but is not compatible with conventional computer modems. There is what looks like a RS-232 socket on the back of the Braille component, but the instructions for the Telebraille state that this jack is for "future use" and that no computer devices should be attached to it.

A graphic Braille display can be used in sensing graphic data such as maps, images, and text data that require multiline display capabilities such spreadsheets and equations. Graphic Braille displays available in the market are DV-2 (from KGS ), Hyperbraille, and TACTISPLAY Table/Walk (from Tactisplay Corp.). For example, TACTISPLAY Table can show 120*100 resolution refreshable Braille graphics on one page. This video shows operation of the device.

There is no treatment, surgical or otherwise, for hearing loss due to the most common causes (age, noise, and genetic defects). For a few specific conditions, surgical intervention can provide a remedy:

- surgical correction of superior canal dehiscence

- myringotomy, surgical insertion of drainage ventilation tubes in the tympanic membrane. Such placement is usually temporary until the underlying pathology (infection or other inflammation) can be resolved.

- radiotherapy or surgical excision of vestibular schwannoma or acoustic neuroma, though, in most cases, it is unlikely that hearing will be preserved

- Stapedectomy and stapedotomy for otosclerosis - replacement or reshaping of the stapes bone of the middle ear can restore hearing in cases of conductive hearing loss

Surgical and implantable hearing aids are an alternative to conventional external hearing aids.

If the ear is dry and not infected, an air conduction aid could be tried; if the ear is draining, a direct bone condition hearing aid is often the best solution. If the conductive part of the hearing loss is more than 30–35 dB, an air conduction device could have problems overcoming this gap. A bone-anchored hearing aid could, in this situation, be a good option.

The active bone conduction hearing implant Bonebridge is also an option. This implant is invisible under the intact skin and therefore minimises the risk of skin irritations.

Cochlear implants improve outcomes in people with hearing loss in either one or both ears. They work by artificial stimulation of the cochlear nerve by providing an electric impulse substitution for the firing of hair cells. They are expensive, and require programming along with extensive training for effectiveness.

Cochlear implants as well as bone conduction implants can help with single sided deafness.

Middle ear implants or bone conduction implants can help with conductive hearing loss.

People with cochlear implants are at a higher risk for bacterial meningitis. Thus, meningitis vaccination is recommended. People who have hearing loss, especially those who develop a hearing problem in childhood or old age, may need support and technical adaptations as part of the rehabilitation process. Recent research shows variations in efficacy but some studies show that if implanted at a very young age, some profoundly impaired children can acquire effective hearing and speech, particularly if supported by appropriate rehabilitation.

Deaf-mute is a term which was used historically to identify a person who was either deaf using a sign language or both deaf and could not speak. The term continues to be used to refer to deaf people who cannot speak an oral language or have some degree of speaking ability, but choose not to speak because of the negative or unwanted attention atypical voices sometimes attract. Such people communicate using sign language. Some consider it to be a derogatory term if used outside its historical context; the preferred term today is simply "deaf".

Treatment of APD typically focuses on three primary areas: changing learning environment, developing higher-order skills to compensate for the disorder, and remediation of the auditory deficit itself. However, there is a lack of well-conducted evaluations of intervention using randomized controlled trial methodology. Most evidence for effectiveness adopts weaker standards of evidence, such as showing that performance improves after training. This does not control for possible influences of practice, maturation, or placebo effects. Recent research has shown that practice with basic auditory processing tasks (i.e. auditory training) may improve performance on auditory processing measures and phonemic awareness measures. Changes after auditory training have also been recorded at the physiological level. Many of these tasks are incorporated into computer-based auditory training programs such as Earobics and Fast ForWord, an adaptive software available at home and in clinics worldwide, but overall, evidence for effectiveness of these computerised interventions in improving language and literacy is not impressive. One small-scale uncontrolled study reported successful outcomes for children with APD using auditory training software.

Treating additional issues related to APD can result in success. For example, treatment for phonological disorders (difficulty in speech) can result in success in terms of both the phonological disorder as well as APD. In one study, speech therapy improved auditory evoked potentials (a measure of brain activity in the auditory portions of the brain).

While there is evidence that language training is effective for improving APD, there is no current research supporting the following APD treatments:

- Auditory Integration Training typically involves a child attending two 30-minute sessions per day for ten days.

- Lindamood-Bell Learning Processes (particularly, the Visualizing and Verbalizing program)

- Physical activities that require frequent crossing of the midline (e.g., occupational therapy)

- Sound Field Amplification

- Neuro-Sensory Educational Therapy

- Neurofeedback

However, use of a FM transmitter has been shown to produce significant improvements over time with children.

Currently, no forms of treatment have proven effective in treating amusia. One study has shown tone differentiation techniques to have some success, however future research on treatment of this disorder will be necessary to verify this technique as an appropriate treatment.

Treating auditory verbal agnosia with intravenous immunoglobulin (IVIG) is controversial because of its inconsistency as a treatment method. Although IVIG is normally used to treat immune diseases, some individuals with auditory verbal agnosia have responded positively to the use of IVIG. Additionally, patients are more likely to relapse when treated with IVIG than other pharmacological treatments. IVIG is, thus, a controversial treatment as its efficacy in treating auditory verbal agnosia is dependent upon each individual and varies from case to case.

In addition to active speech therapy, pharmaceuticals have also been considered as a useful treatment for expressive aphasia. This area of study is relatively new and much research continues to be conducted.

The following drugs have been suggested for use in treating aphasia and their efficacy has been studied in control studies.

- Bromocriptine – acts on Catecholamine Systems

- Piracetam – mechanism not fully understood, but most likely interacts with cholinergic and glutamatergic receptors, among others

- Cholinergic drugs (Donepezil, Aniracetam, Bifemelane) – acts on acetylcholine systems

- Dopaminergic psychostimulants: (Dexamphetamine, Methylphenidate)

The most effect has been shown by piracetam and amphetamine, which may increase cerebral plasticity and result in an increased capability to improve language function. It has been seen that piracetam is most effective when treatment is begun immediately following stroke. When used in chronic cases it has been much less efficient.

Bromocriptine has been shown by some studies to increase verbal fluency and word retrieval with therapy than with just therapy alone. Furthermore, its use seems to be restricted to non-fluent aphasia.

Donepezil has shown a potential for helping chronic aphasia.

No study has established irrefutable evidence that any drug is an effective treatment for aphasia therapy. Furthermore, no study has shown any drug to be specific for language recovery. Comparison between the recovery of language function and other motor function using any drug has shown that improvement is due to a global increase plasticity of neural networks.

Deafblind people communicate in many different ways as determined by the nature of their condition, the age of onset, and what resources are available to them. For example, someone who grew up deaf and experienced vision loss later in life is likely to use a sign language (in a visually modified or tactile form). Others who grew up blind and later became deaf are more likely to use a tactile mode of their spoken/written language. Methods of communication include:

- Use of residual hearing (speaking clearly, hearing aids) or sight (signing within a restricted visual field, writing with large print).

- Tactile signing, sign language, or a manual alphabet such as the American Manual Alphabet or Deaf-blind Alphabet (also known as "two-hand manual") with tactile or visual modifications.

- Interpreting services (such as sign language interpreters or communication aides).

- Communication devices such as Tellatouch or its computerized versions known as the TeleBraille and Screen Braille Communicator.

Multisensory methods have been used to help deafblind people enhance their communication skills. These can be taught to very young children with developmental delays (to help with pre-intentional communication), young people with learning difficulties, and older people, including those with dementia. One such process is Tacpac.

Deafblind amateur radio operators generally communicate on 2-way radios using Morse code.

Following are some precautions that should be taken to avoid aphasia, by decreasing the risk of stroke, the main cause of aphasia:

- Exercising regularly

- Eating a healthy diet

- Keeping alcohol consumption low and avoiding tobacco use

- Controlling blood pressure

There is no method available to completely cure anomic aphasia. However, there are treatments to help improve word-finding skills.

Although a person with anomia may find it difficult to recall many types of words such as common nouns, proper nouns, verbs, etc., many studies have shown that treatment for object words, or nouns, has shown promise in rehabilitation research. The treatment includes visual aids, such as pictures, and the patient is asked to identify the object or activity. However, if that is not possible, then the patient is shown the same picture surrounded by words associated with the object or activity. Throughout the process, positive encouragement is provided. The treatment shows an increase in word-finding during treatment; however, word identifying decreased two weeks after the rehabilitation period. Therefore, it shows that rehabilitation effort needs to be continuous for word-finding abilities to improve from the baseline. The studies show that verbs are harder to recall or repeat, even with rehabilitation.

Other methods in treating anomic aphasia include Circumlocution Induced Naming therapy (CIN), wherein the patient uses circumlocution to assist with his or her naming rather than just being told to name the item pictured after given some sort of cue. Results suggest that the patient does better in properly naming objects when undergoing this therapy because CIN strengthens the weakened link between semantics and phonology for patients with anomia, since they often know what an object is used for but cannot verbally name it.

Anomia is often burdensome on the families and friends of those suffering from it. One way to overcome this burden is computer-based treatment models, effective especially when used with clinical therapy. Leemann et al. provided anomic patients with computerized-assisted therapy (CAT) sessions, along with traditional therapy sessions using treatment lists of words. Some of the patients received a drug known to help relieve symptoms of anomia (levodopa) while others received a placebo. The researchers found that the drug had no significant effects on improvement with the treatment lists, but almost all of the patients improved after the CAT sessions. They concluded that this form of computerized treatment is effective in increasing naming abilities in anomic patients.

Additionally, one study researched the effects of using "excitatory (anodal) transcranial direct current stimulation" over the right temporo-parietal cortex, a brain area that seems to correlate to language. The electrical stimulation seemed to enhance language training outcome in patients with chronic aphasia.

Intervention services will be guided by the strengths and needs determined by the speech and language evaluation. The areas of need may be addressed individually until each one is functional; alternatively, multiple needs may be addressed simultaneously through the intervention techniques. If possible, all interventions will be geared towards the goal of developing typical communicative interaction. To this end, interventions typically follow either a preventive, remedial, or compensatory model. The preventive service model is common as an early intervention technique, especially for children whose other disorders place them at a higher risk for developing later communication problems. This model works to lessen the probability or severity of the issues that could later emerge. The remedial model is used when an individual already has a speech or language impairment that he/she wishes to have corrected. Compensatory models would be used if a professional determines that it is best for the child to bypass the communication limitation; often, this relies on AAC.

Language intervention activities are used in some therapy sessions. In these exercises, an SLP or other trained professional will interact with a child by working with the child through play and other forms of interaction to talk to the child and model language use. The professional will make use of various stimuli, such as books, objects, or simple pictures to stimulate the emerging language. In these activities, the professional will model correct pronunciation, and will encourage the child to practice these skills. Articulation therapy may be used during play therapy as well, but involves modeling specific aspects of language—the production of sound. The specific sounds will be modeled for the child by the professional (often the SLP), and the specific processes involved in creating those sounds will be taught as well. For example, the professional might instruct the child in the placement of the tongue or lips in order to produce certain consonant sounds.

Technology is another avenue of intervention, and can help children whose physical conditions make communication difficult. The use of electronic communication systems allow nonspeaking people and people with severe physical disabilities to engage in the give and take of shared thought.

Students identified with a speech and language disability often qualify for an Individualized Education Plan as well as particular services. These include one-on-one services with a speech and language pathologist. Examples used in a session include reading vocabulary words, identifying particular vowel sounds and then changing the context, noting the difference. School districts in the United States often have speech and language pathologists within a special education staff to work with students. Additionally, school districts can place students with speech and language disabilities in a resource room for individualized instruction. A combination of early intervention and individualized support has shown promise increasing long-term academic achievement with students with this disability.

Students might work individually with a specialist, or with a specialist in a group setting. In some cases, the services provided to these individuals may even be provided in the regular education classroom. Regardless of where these services are provided, most of these students spend small amounts of time in therapy and the large majority of their time in the regular education classroom with their typically developing peers.

Therapy often occurs in small groups of three or four students with similar needs. Meeting either in the office of the speech-language pathologist or in the classroom, sessions may take from 30 minutes to one hour. They may occur several times per week. After introductory conversations, the session is focused on a particular therapeutic activity, such as coordination and strengthening exercises of speech muscles or improving fluency through breathing techniques. These activities may take the form of games, songs, skits, and other activities that deliver the needed therapy. Aids, such as mirrors, tape recorders, and tongue depressors may be utilized to help the children to become aware of their speech sounds and to work toward more natural speech production.

The intensity of aphasia therapy is determined by the length of each session, total hours of therapy per week, and total weeks of therapy provided. There is no consensus about what “intense” aphasia therapy entails, or how intense therapy should be to yield the best outcomes. A 2016 Cochrane review of speech and language therapy for people with aphasia found that treatments that are higher intensity, higher dose or over a long duration of time led to significantly better functional communication but people were more likely to drop out of high intensity treatment (up to 15 hours per week).

Intensity of therapy is also dependent on the recency of stroke. People with aphasia react differently to intense treatment in the acute phase (0–3 months post stroke), sub-acute phase (3–6 months post stroke), or chronic phase (6+ months post stroke). Intensive therapy has been found to be effective for people with nonfluent and fluent chronic aphasia, but less effective for people with acute aphasia.> People with sub-acute aphasia also respond well to intensive therapy of 100 hours over 62 weeks. This suggests people in the sub-acute phase can improve greatly in language and functional communication measures with intensive therapy compared to regular therapy.

Many of these types of disorders can be treated by speech therapy, but others require medical attention by a doctor in phoniatrics. Other treatments include correction of organic conditions and psychotherapy.

In the United States, school-age children with a speech disorder are often placed in special education programs. Children who struggle to learn to talk often experience persistent communication difficulties in addition to academic struggles. More than 700,000 of the students served in the public schools’ special education programs in the 2000-2001 school year were categorized as having a speech or language impediment. This estimate does not include children who have speech and language impairments secondary to other conditions such as deafness". Many school districts provide the students with speech therapy during school hours, although extended day and summer services may be appropriate under certain circumstances.

Patients will be treated in teams, depending on the type of disorder they have. A team can include SLPs, specialists, family doctors, teachers, and family members.

In incidents where tumors and their pressure effects are the cause of pure word deafness, removal of the tumor has been shown to allow for the return of most auditory verbal comprehension.

As of 2012 there has only been one small-scale study comparing CROS systems.

One study of the BAHA system showed a benefit depending on the patient's transcranial attenuation. Another study showed that sound localisation was not improved, but the effect of the head shadow was reduced.

There is no curative treatment for this condition. Supportive management is helpful.

Constraint-induced aphasia therapy (CIAT) is based on similar principles as constraint-induced movement therapy developed by Dr. Edward Taub at the University of Alabama at Birmingham. Constraint-induced movement therapy is based on the idea that a person with an impairment (physical or communicative) develops a "learned nonuse" by compensating for the lost function with other means such as using an unaffected limb by a paralyzed individual or drawing by a patient with aphasia. In constraint-induced movement therapy, the alternative limb is constrained with a glove or sling and the patient is forced to use the affected limb. In constraint-induced aphasia therapy the interaction is guided by communicative need in a language game context, picture cards, barriers making it impossible to see other players' cards, and other materials, so that patients are encouraged ("constrained") to use the remaining verbal abilities to succeed in the communication game.

Two important principles of constraint-induced aphasia therapy are that treatment is very intense, with sessions lasting for up to 6 hours over the course of 10 days and that language is used in a communication context in which it is closely linked to (nonverbal) actions. These principles are motivated by neuroscience insights about learning at the level of nerve cells (synaptic plasticity) and the coupling between cortical systems for language and action in the human brain. Constraint-induced therapy contrasts sharply with traditional therapy by the strong belief that mechanisms to compensate for lost language function should not be used unless absolutely necessary, even in everyday life.

It is believed that CIAT works by the mechanism of increased neuroplasticity. By constraining an individual to use only speech, it is believed that the brain can reestablish old neural pathways and recruit new neural pathways to compensate for lost function.

The greatest advantage of CIAT has been seen in its treatment of chronic aphasia (lasting over 1 year). Studies of CIAT have shown that further improvement is possible even after a patient has reached a "plateau" period of recovery. It has also been proven that the benefits of CIAT are retained long term. However, improvements only seem to be made while a patient is undergoing intense therapy. A recent breakthrough has been achieved by combining constraint-induced aphasia therapy with drug treatment, which led to an amplification of therapy benefits.

Elective mutism was defined as a refusal to speak in almost all social situations (despite normal ability to do so), while selective mutism is considered to be a "failure" to speak in specific situations and is strongly associated with social anxiety disorder. In contrast to selective mutism, someone who is electively mute may not speak in any situation, as is usually shown in books and movies. Elective mutism is often attributed to defiance or the effect of trauma.

Some patients have been treated by injecting botulinum toxin (botox) near the vocal cords. This does not prevent the vocalizations, but the partial paralysis that results helps to control the volume of any outbursts. Surprisingly, botox injections result in more generalized relief of tics than the vocal relief expected.

The severity and frequency of outbursts can also be decreased by surgically disabling nuclei in the thalamus, the globus pallidus and the cingulate cortex.
