This study compared the speech and prosody-voice profiles for 30 male speakers with either high-functioning autism (HFA) or Asperger syndrome (AS), and 53 typically developing male speakers. Both HFA and AS groups had more residual articulation distortion errors and utterances coded as inappropriate for phrasing, stress, and resonance. AS speakers…

Ten esophageal speakers and ten normal speakers produced repetitions of the disyllable /mama/ using five different conditions of syllable stress. Nine normal listeners judged both relative and absolute syllable stress. Reliable judgments were made of the syllable stress, and speakers were able to effect systematic changes in listener perceptions…

Two tracheoesophageal speakers experienced in use of the tracheostoma valve (TSV) produced speech samples varying with location of contrastive stress, sentence intonation, and use of TSV. Listeners (n=34) found that TSV-use reduced speaker ability to signal suprasegmentals; however, locus of the suprasegmentals, particularly stress placement,…

Ten adults with dysarthria of various etiologies, type, and severity were compared to age-matched and gender-matched nondysarthric speakers on 40 short sentences. Results indicated reduced intonation values for the dysarthric group and varying rates as a function of subject group and sentence type. Results suggest that dysarthria is a deficit in…

Vowels produced by four deaf women were analyzed spectrographically to study acoustic correlates of vocal tract deformation. Formant structure evaluated on isovowel lines disclosed consistent neutralization of vowels, which is attributed to observed restricted horizontal movements of the tongue within the oral and pharyngeal cavities.
