Stimuli phrases of adductor spasmodic dysphonia phonatory break in mandarin Chinese / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the characteristics of adductor spasmodic dysphonia phonatory break in mandarin Chinese and select the stimuli phrases.@*METHOD@#Thirty-eight patients with adductor spasmodic dysphonia were involved in this study. Standard phrase " fù mŭ xīn" and a speech corpus in mandarin Chinese with 229 syllables covering all vowel and constant of mandarin Chinese were selected. Every patient read the phrases above twice in normal speed and comfortable voice. Two auditory perpetual speech pathologists marked phonatory break syllables respectively. The frequency of phonatory break syllables and their located phrases were calculated, rated and described. The phrases including the most phonatory break syllables were selected as stimuli phrases, the phonatory break frequency of which was also higher than that of standard phrase "fù mŭ xīn".@*RESULT@#Phonatory break happened in the reading of all patients. The average number of phonatory break syllables was 14 (3-33). Phonatroy break occurred when saying 177 (77.3%) syllables in the speech corpus. The syllables "guŏ, rén, zāng, diàn, chē, gè, guăn, a, bā, ne, de" broke in 23.1%-41.0% patients. These syllables belonged to the phrases "pĭng guŏ, huŏ chē, shì de, nĭ shì gè hăo rén, wŏ mén shì yŏu zŏng shì bă qĭn shì nong dé hĕn zāng, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a,wŏ yīng gāi zài xìn lĭ xiĕ yī xiē shén mē ne?". Thirty-seven patients (97.3%) had phonatory break in above mentioned words. Ratios of these words phonatory break also were more than "fù mŭ xīn".@*CONCLUSION@#Adductor spasmodic dysphonic patients exhibited different degrees of phonatory break in mandarine Chinese. The phrases" shì de, pĭng guŏ, huŏ chē, nĭ shì gè hăo rén, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a" were recommended as stimuli phrases for adductor spasmodic dysphonia evaluation.

The Effects of Voice Training Therapy on Dysphonia in Patients with Vocal Nodules / 听力学及言语疾病杂志

Objective To investigate the effect of voice training therapy on the voice improvement in patients with vocal nodules .Methods Twenty one patients with vocal nodules were recruited and were evaluated by the GRBAS perpetual evaluation ,voice handicap index (VHI)-30 subjective assessment ,vocal laryngostroboscopy , maximum phonation time (MPT) and acoustic analysis pre- and post-therapy .These patients completed 5 cour‐ses of voice training .Results The VHI value(29 .48 ± 21 .21) of post-therapy was less than the value (52 .95 ± 24 . 30)of pre -therapy (P< 0 .01) .There were significantly differences in voice perpetual evaluation between pre -training and post-training ,especially for G (grade) (P<0 .01) and R (roughness) (P<0 .01) .The post-training laryngostrobescopy vocal vibration improved comparing with pre-therapy in the closure of vocal cords ,symmetry of vibration ,the mucosal wave and vibration regularity of the vocal cords .After therapy ,three patient nodules dis‐appeared ,thirteen patient nodules became smaller ,and five patient nodules remained the same .The maximum pho‐nation time (MPT) (12 .54 ± 3 .68)of post-therapy was longer than MPT(8 .87 ± 3 .75) of pre-therapy MPT(P<0 .01) .The jitter value (0 .18% ± 0 .08% ) of post -therapy was less than that of pre-therapy(0 .43% ± 0 .31% ) (P<0 .01) .The shimmer of post -therapy (2 .10% ± 0 .98% ) was less than that of pre -therapy (4 .55% ± 1 .80% )(P<0 .01) ,The ratio of noise to harmonic(NHR)(0 .0034 ± 0 .0022 dB) of post-therapy was significantly less than NHR(0 .0184 ± 0 .028 dB)(P<0 .05) of pre-therapy .Conclusion The voice therapy could significantlyimprove voice of patients with vocal nodules .
