Étude des paramètres temporels de la parole après laryngectomie totale (voix oro-oesophagienne et trachéo-oesophagienne)

Abstract : The present study is a state of the art of speech ability after total laryngectomy. It focuses on global (of an utterance) and local (speech segments) temporal parameters of elocution. A text corpus based on literature extracts enabled to evaluate various temporal parameters through three categories (reading, spontaneous speech and diadokokinesis). The corpus was submitted to 12 subjects using oesophageal voice, 17 subjects using tracheoesophageal voice and 12 control subjects. Results show that patients’ speech velocity was reduced for the three categories of communication, in particular for the patients with oesophageal voice. Pauses frequency as well as the expiration number also show a significant impact of total laryngectomy on elocution velocity and fluidity. The vowels measurements were performed with more precision: the oesophageal group presented longer vowel durations than other groups. In addition, the vowel times were observed to differ more (between the recorded pairs of sentences) for the control group than other groups. Speech malfunction might trouble life quality and are linked to voice quality and voice handicap. Significative correlations were observed between some aspects of life quality and voice handicap; moreover, laryngectomised subjects were shown to feel a strong voice handicap when presenting a slow read velocity and reverse.
