An important clinical issue concerns the efficacy of current voice therapy approaches in treating voice disorders, such as vocal nodules. Much research focuses on finding reliable methods for documentation of treatment results. In this second treatment study of ten patients with vocal nodules, who participated in a behaviorally based voice therapy program,(More)
Long-term recordings with reliable methods are desirable for objective documentation of voice use during natural conditions. The purpose of this study was to evaluate a voice accumulator (VAC) with a digital audiotape (DAT) recorder as a reference. The VAC is based on a microprocessor that accumulates information about fundamental frequency (F0) and(More)
Preschool teachers are at risk for developing voice problems such as vocal fatigue and vocal nodules. The purpose of this report was to study preschool teachers' voice use during work. Ten healthy female preschool teachers working at daycare centers (DCC) served as subjects. A binaural recording technique was used. Two microphones were placed on both sides(More)
Phonation into glass tubes ('resonance tubes'), keeping the free end of the tube in water, has been a frequently used voice therapy method in Finland and more recently also in other countries. The purpose of this exploratory study was to investigate what effects tube phonation with and without water has on the larynx. Two participants were included in the(More)
OBJECTIVE To perform perceptual and acoustical analyses of tracheoesophageal (TE) speech and relate these analyses to self-reported voice handicap. METHODS Recordings of 35 TE speakers were perceptually assessed by 5 speech-language pathologists. Acoustical analyses were made of voice aspects and temporal speech aspects. Self-assessments of voice were(More)
This study aimed to relate the results of physiological measurements of the pharyngoesophageal (PE) segment in subjects using tracheoesophageal (TE) or esophageal (E) speech with perceptual assessment of the speakers' voice quality and acoustic measurements of the voice function. It further aimed to investigate possible differences in appearance and(More)
With current progress in genetic research, autosomal, dominant, hereditary, neurodegenerative diseases, affecting the cerebellum and cerebellar connections, are increasingly diagnosed as spinocerebellar ataxias (SCA). In the present study speech samples from 21 subjects with spinocerebellar ataxia (SCA), and 21 matched control subjects were analyzed using(More)
This study presents results from high-speed imaging recordings of the voice source, that is the pharyngo-esophageal segment, in four laryngectomized men. The subjects were asked to produce VCV-syllables with voiced and voiceless stop consonants during simultaneous high-speed imaging recordings and audio recordings. A general and detailed visuo-perceptual(More)
The speech of nine laryngectomized persons is analysed. Both tracheo-esophageal and esophageal speakers are included. The speech performance of the subjects is evaluated while they are reading texts aloud with varying amounts of noise in their ears. One hypothesis is that the amount of noise will influence the articulation skill and voice behaviour of the(More)
