Dans cet article, une méthode de traitement numérique est décrite pour modifier le contraste tonal qui est défini comme la plus grande différence de fréquences entre les pics et les vallées des courbes de hauteur dans les énoncés monosyllabiques. Dans un environnement calme et bruyant, des mots au ton mandarin modifié ont été présentés à des auditeurs chinois malentendants présentant une perte auditive neurosensorielle modérée à sévère. Les auditeurs ont été invités à identifier quatre mots monosyllabiques alternatifs qui se distinguaient respectivement par les tons 1, 2, 3 et 4. En employant cette méthode, il a été constaté que la parole modifiée avec un contraste de tonalité amélioré produisait des gains modérés dans le pourcentage d'identification correcte des tonalités par rapport aux tonalités de parole non modifiées avec uniquement une amplification par compression. Il a également été constaté que la réduction du contraste des tons réduisait généralement le degré d’identification correcte des tons. Ces résultats confortent donc l’affirmation selon laquelle une aide auditive avec des modifications de tonalité est effectivement efficace pour les Chinois malentendants.

Abstract: In this paper, a digital processing method is described for modifying tone contrast that is defined as the greatest difference in frequencies between peaks and valleys of pitch curves in monosyllable utterances. Under quiet and noisy backgrounds, modified Mandarin tone words were presented to hearing-im- paired Chinese listeners with moderate to severe sensorineural hearing loss. The listeners were asked to identify four alternative monosyllable words which were distinguishable by tones 1, 2, 3 and 4 respectively. Employing this method, it was found that modified speech with enhanced tone contrast yielded moderate gains in the percentage of correct identification of the tones when compared to unmodified speech tones with only compression amplification. It was likewise found that reducing tone contrast generally reduced the degree of correct tone identification. These findings therefore offer support to the assertion that a hearing aid with tone modifications is indeed effective for hearing-impaired Chinese.
