Purpose To identify phonetic errors in dysarthric speech following traumatic mutism.
To establish a complete articulatory inventory to determine the course of recovery and identify patterns.
Methods Every 3 weeks articulatory, phonatory, respiratory, and prosodic skills were tested and a spontaneous speech sample was recorded.
Articulatory testing included the repetition of two-syllable words with all German consonants in the word-medial position.
The utterances were narrowly transcribed and examined spectrographically.
Aphasia testing was done with the revised Token Test.
Phoniatric testing was conducted.
Results Traumatic dysarthria is phonetically sensitive to articulation which demands closure with specific contact pressure, a specific structure to maintain the turbulent flow of air, and a gross displacement of the tongue.
