Etude de paramètres acoustiques des voix de patients traités pour un cancer ORL dans le cadre du projet C2SI

Abstract : As part of the Carcinologic Speech Severity Index project (C2SI), the voices of 35 patients who were treated for oral and pharyngeal cancer were studied using different acoustic parameters, coupled with automated speech recognition. The study revealed, by comparison with a control group, significant harmonic poverty on sustained /a/ as well as on read text, as well as a spectral degradation of vowels and consonants, in particular in the areas of formants F2 to F4, correlated with intelligibility and misalignment on a set of pseudo-words. However, the study does not reveal any significant difference in the histogram of the fundamental of the voice between the control and patient groups. On the other hand, there is a poor frequency discrimination of vowels and extreme consonants (in particular / s / m /) for more than 50% of patients, correlated with loss of intelligibility.
