Acoustic signal typing for evaluation of voice quality in tracheoesophageal speech.

SUMMARY Because of the aperiodicity of many tracheoesophageal voices, acoustic analysis of the tracheoesophageal voice is less straightforward than that of the normal voice. This study presents the development and testing of an acoustic signal typing system based on visual inspection of a narrow-band spectrogram that can be used by researchers for classification of voice quality in tracheoesoph...

Automatic tracheoesophageal voice typing using acoustic parameters

The acoustics of isolated vowels, e.g. of /a/, have in many studies been linked to pathological voice types, such as tracheoesophageal (TE) voice. To study the possibilities of objective and automatic classification of pathological TE voice types, the acoustic features of /a/ were quantified and subsequently classified using a suit of machine learning technologies. Best classification was achie...

The evaluation of diagnostics and therapies includes more and more subjective, i.e. emotional and social aspects. Focussing on the handicap experienced by dysphonic patients, the Voice Handicap Index (VHI) has previously been found to be of significant clinical and scientific value for different voices. In this study the VHI questionnaire was applied to demonstrate the voice handicap of 20 male...

Objective assessment of tracheoesophageal and esophageal speech using acoustic analysis of voice.

The aim of this study was to analyze the voice quality of alaryngeal tracheoesophageal and esophageal speech, and to determine which of them is more similar to laryngeal voice production, and thus more acceptable as a rehabilitation method of laryngectomized persons. Objective voice evaluation was performed on a sample of 20 totally laryngectomized subjects of both sexes, average age 61.3 years...

Tracheoesophageal speech: A dedicated objective acoustic assessment

After total laryngectomy, the placement of a tracheoesophageal (TE) prosthesis offers the possibility to recover a new voice. However, the quality of the resulting TE speech is known to be degraded. To assess a patient’s voice, current approaches rely either on quality-of-life questionnaires or on a perceptual evaluation carried out by speech therapists. These two methods exhibit the disadvanta...
