OBJECTIVES Carbon dioxide (CO2) laser cordectomy is considered one of the modalities of choice for treatment of early glottic carcinoma. In addition to its comparable oncological results with radiotherapy and open surgical procedures, it preserves of laryngeal functions including voice production. The aim of this study was to detect how the larynx compensates for voice production after differen...

The present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of English as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. Their overall academic writing quality scores assigned based on portfolio assessment were studied i...

Vowel prolongation is often used to evaluate disordered voice production. In light of previous findings showing that co-articulation has significant influence on laryngeal function measures, the practice of using prolonged vowels to represent a speech sample is questioned. To test whether disordered and normal voice during vowel production is generalizable to connected speech, three speaking ta...

Introduction Smoking is a major risk factor for numerous diseases; it is necessary to analyze the impact that the habit can have on vocal health. Objectives To determine the influence of smoking on changes in vocal production and lung vital capacity compared with nonsmokers. Methods This cross-sectional study compared smokers and nonsmokers (24 subjects each). Each participant underwent a vocal...

PURPOSE OF REVIEW This paper describes recent advances in perceptual, acoustic, aerodynamic, and endoscopic imaging methods for assessing voice function. RECENT FINDINGS We review advances from four major areas. PERCEPTUAL ASSESSMENT: Speech-language pathologists are being encouraged to use the new consensus auditory-perceptual evaluation of voice inventory for auditory-perceptual assessment ...

Voice production models are used for speech compression thus reducing the encoding data rates and storage space for speech signaling processing. The legacy voice production model consists of a vocal source model and a vocal tract model. This paper presents a simpler voice production model adapted to waveform coding of speech: the Mathieu Waveform Coder (MWC) model. The MWC model yields weighted...

This is a review of recent work on source-filter composition of voiced sounds, describing various alternatives of defining a source function w i t h implications for a m r e profound understandinq of the acoustic processes involved an8 their mdelling in equivalent netmrks. The theoretical study is backed up by experiments with inverse fi l tering and other types of glottq-dphy. Special attentio...

Vibrato used in Noh play was investigated using electroglottographic and acoustical analyses. Laryngeal movements were successfully obtained from the EGG signal and its derivative in order to study how the peculiar and expressive voice qualities were produced during vibrato. The slow wide vibrato of Noh was achieved not only by the F0 modulation but also by changing the degree of constriction a...

Evidence regarding visually guided limb movements suggests that the motor system learns and maintains neural maps between motor commands and sensory feedback. Such systems are hypothesized to be used in a feed-forward control strategy that permits precision and stability without the delays of direct feedback control. Human vocalizations involve precise control over vocal and respiratory muscles...
