Abstract
The aim of this study was to investigate voice characteristics of adductive spasmodic dysphonia(ADSD) by measuring electroglottal and acoustic examination at the sentence level. The clinical records of 86 ADSD female patients (age group of 20~50 years) and the control records of 86 normal females (age group of 20~40 years) were recorded by speech studio(Laryngograph Ltd., UK). An independent t-test was used to compare ADSD and normal group. Results were as follows. (1) Fundamental frequency($F_0$) was significantly decreased in ADSD compared with normal group. (2) Irregularity of frequency and closed quotient(CQ) was significantly increased in ADSD compared with normal group. (3) Voiceless duration increased and voiced duration was significantly decreased in ADSD compared with normal group. (4) Fricative duration was increased in ADSD compared with normal group but it wasn't significant. In conclusion, strained, tight and choked voice shows an increase of CQ, tremor voice shows an increase of irregularity of frequency and less feminine voice shows decrease of $F_0$. Increase of voiceless duration and fricative duration and decrease of voiced duration related with diminution speech intelligibility
