The reliability of listeners' ratings of voice quality is a central issue in voice research because of the clinical primacy of such ratings and because they are the standard against which other measures are evaluated. However, an extensive literature review indicates that both intrarater and interrater reliability fluctuate greatly from study to study.(More)
PURPOSE The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was developed to provide a protocol and form for clinicians to use when assessing the voice quality of adults with voice disorders (Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kramer, & Hillman, 2009). This study examined the reliability and the empirical validity of the CAPE-V when(More)
We report differential patterns of swallowing in 40 patients with their first ischemic middle cerebral artery (MCA) stroke and compare these to 20 nonstroke controls. Stroke patients were divided a priori, into groups by right or left and, post hoc, primarily anterior or posterior MCA territory lesions. The left hemisphere subgroup was differentiated from(More)
The objective of this research was to identify perceptually relevant features of 30 dysphonic female voices. The perceptual dimensions used by listeners in judging the similarity of the dysphonic voices were derived in two multidimensional scaling (MDS) procedures using ALSCAL. Three dimensions were extracted in each MDS solution and accounted for(More)
Voice onset time (VOT) and vowel duration characteristics of speakers following the Singer-Blom technique of tracheoesophageal puncture (1980) were compared to those of traditional esophageal and laryngeal speakers. Fifteen subjects in each of the three speaker groups produced the words /pik/, /kap/, /kup/ in a carrier phrase while audio recordings were(More)
This investigation was designed to measure voice Fo changes related to single motor unit (SMU) contractions in the cricothyroid and thyroarytenoid muscles. Four subjects (3 men and 1 woman) were recorded producing a prolonged vowel at modal pitch and loudness levels while simultaneous recordings of electromyograms (EMG) from the muscles were obtained.

OBJECTIVES/HYPOTHESIS Singing-voice classification is often considered the cornerstone of a classical singer's identity. Traditionally, classification has been a highly subjective, nonstandardized process. As a result, misclassification of the singing voice is thought to be common, especially in young singers. Long-term average spectrum (LTAS) average is an(More)
Twelve male and 12 female total laryngectomy patients who received the tracheoesophageal puncture (TEP) as a means of vocal rehabilitation served as subjects for this investigation. Recordings were made of these subjects' speech produced with four prosthetic/occlusion conditions: (1) duckbill prosthesis with tracheostoma valve; (2) duckbill prosthesis with(More)
