BACKGROUND neurological dysphonias are normally associated to dysarthrias and play an important role when determining the correct diagnosis. The acoustic analysis of the voice is important for understanding the speech motor disorders present in dysarthric patients. AIM to describe the acoustic and auditory-perceptual characteristics of the voice of the different types of dysarthria. METHOD ...

School teachers have an elevated risk of voice problems due to the vocal demands in the workplace. Studies suggest that male and female teachers respond differently, which may explain why female teachers have an elevated risk for vocal disorders. Presented will be an amalgamation of two studies investigating gender differences in voice use in the school setting. In the first study, 57 teachers ...

background: repeated efforts by researchers to impose voice changes by laryngeal surface electrical stimulation (ses) have come to no avail. this present pre-experimental study employed a novel method for ses application so as to evoke the motor potential of the internal superior laryngeal nerve (isln) and create voice changes. methods: thirty-two normal individuals (22 females and 10 males) pa...

Speech quality is an interesting and very important aspect not only from linguistic and/or phonetic viewpoint but also from the viewpoint of speech technology. This study has been conducted from the latter point of view. A method has been developed based on the analysis-synthesis technique which enables to control voice quality by independently manipulating the voice source and the vocal tract ...

OBJECTIVE The purposes of this study are to investigate the impact of topical anesthetic alone and with concurrent laryngeal telescopic examination on acoustic characteristics of vocal fold function. Comparison with phonation in controlled conditions may imply diagnostic information from the examination. STUDY DESIGN Thirty males evaluated as having a normal voice were included in the study. ...

Background: The effect of subthalamic nucleus deep brain stimulation (STN-DBS) on the voice features in Parkinson’s disease (PD) is controversial. No study has evaluated the voice features of PD underwent STN-DBS by the acoustic, perceptual, and patient-based assessments comprehensively. Furthermore, there is no study to investigate prosodic features before and after DBS in PD. The curren...

Precise control of the vocal tract configuration is of critical importance for producing the desired acoustic characteristics of singing. The pattern of acoustic resonances generated by a given vocal tract shape influences vowel identity, voice quality (timbre), and, to some degree, the spectral characteristics of the voice excitation source itself. This chapter is broadly focused on how the vo...
