Purpose: This research gathered pilot data on the effects of a typical collegiate athletic season on the male coach's voice.

Materials And Methods: Ten male coaches and ten age- and sex-matched controls participated. Qualitative and quantitative analyses were performed to assess group differences in: 1) written self-reports obtained during one session, 2) acoustic and aerodynamic variables obtained during regular season and during off-season for the coaches and only once for the controls, and 3) auditory-perceptual data provided by three speech-language pathologists using the Consensus Auditory-Perceptual Evaluation of Voice during one listening session.

Purpose: Research on language planning in adult stuttering is relatively sparse and offers diverging arguments about a potential causative relationship between semantic and phonological encoding and fluency breakdowns. This study further investigated semantic and phonological encoding efficiency in adults who stutter (AWS) by means of silent category and phoneme identification, respectively.

Method: Fifteen AWS and 15 age- and sex-matched adults who do not stutter (ANS) participated.

Unlabelled: The purpose of this study was to compare the speed of phonological encoding between adults who stutter (AWS) and adults who do not stutter (ANS). Fifteen male AWS and 15 age- and gender-matched ANS participated in the study. Speech onset latency was obtained for both groups and stuttering frequency was calculated for AWS during three phonological priming tasks: (1) heterogeneous, during which the participants' single-word verbal responses differed phonemically; (2) C-homogeneous, during which the participants' response words shared the initial consonant; and (3) CV-homogeneous, during which the participants' response words shared the initial consonant and vowel.

To investigate voice changes as they develop over time due to cigarette smoking, women who never smoked (NS), women who smoked less than 10 years (S1), and women who smoked 10 or more years (S2) were compared. Acoustic (fundamental frequency, jitter, shimmer, signal-to-noise ratio), electroglottographic (open, closing, and speed quotients), aerodynamic (subglottal pressure, airflow, laryngeal airway resistance), and perceptual measures were obtained. Fundamental frequency and open quotient significantly decreased and speed quotient significantly increased in S1 and S2; jitter and shimmer significantly increased in S2 only.
