Ten patients diagnosed with adductor spasmodic dysphonia (ADSD) read aloud eight homonyms while ten healthy university students who speak standard Japanese judged the word meanings. Results of the assessments revealed that the intra-evaluator matching was 88.6%, with 19/80 samples (23.8%) misjudged by more than half of the evaluators. These samples were classified as either 1) voiced/unvoiced or 2) an accent kernel position. Homonyms that were constructed from serial voiced syllables (11/19 samples) or with the accent kernel position in the second mora (13/19 samples) tended to be misjudged. Difficulty of speech in ADSD patients affects not only "voice" disorders but also "speech" disorders, including voice pitch adjustment, and these adjustment errors may lead to low speech intelligibility.
