[Contribution and limits of acoustic analysis of the voice and alaryngeal speech with a computerized system].
Through a review of published acoustical analyses of alaryngeal voice and speech, our aim was to establish the interest and the limitations of a computerized acoustical system. One case of esophageal voice and one case of tracheoesophageal voice were analysed with the Kay Elemetrics Multidimensional Voice Program for voice and Computerised Speech Lab for speech. All the acoustical parameters are altered in alaryngeal voice. The automatic calculation of frequential parameters are promising but there are errors due to the importance of altered voicing. Speech analysis is an important complement to evaluate the phonatory behavior of laryngectomized patients.
