Abstract

Tachylalia or tachylogia is extremely rapid speech. Tachylalia occurs in many clutterers and many people who have speech disorders.

Tachylalia is a generic term for speaking fast, and does not need to coincide with other speech problems. Tachylalia by itself is not considered a speech disorder.

Tachylalia may be exhibited as a single stream of rapid speech without prosody, and can be delivered quietly or mumbled. Tachylalia can be simulated by stimulating the brain electronically.

Occurrences

Tachylalia can occur with the following:

- Normal speech

- Cluttering

- Parkinson's disease

- Cluttered speech

- Pressure of speech
