Voice gender discrimination provides a measure of more than pitch-related perception in cochlear implant users.

Abstract Objectives: (1) To investigate whether voice gender discrimination (VGD) could be a useful indicator of the spectral and temporal processing abilities of individual cochlear implant (CI) users; (2) To examine the relationship between VGD and speech recognition with CI when comparable acoust...

      ab: Abstract Objectives: (1) To investigate whether voice gender discrimination (VGD) could be a useful indicator of the spectral and temporal processing abilities of individual cochlear implant (CI) users; (2) To examine the relationship between VGD and speech recognition with CI when comparable acoustic cues are used for both perception processes. Design: VGD was measured using two talker sets with different inter-gender fundamental frequencies (F0), as well as different acoustic CI simulations. Vowel and consonant recognition in quiet and noise were also measured and compared with VGD performance. Study sample: Eleven postlingually deaf CI users. Results: The results showed that (1) mean VGD performance differed for different stimulus sets, (2) VGD and speech recognition performance varied among individual CI users, and (3) individual VGD performance was significantly correlated with speech recognition performance under certain conditions. Conclusions: VGD measured with selected stimulus sets might be useful for assessing not only pitch-related perception, but also spectral and temporal processing by individual CI users. In addition to improvements in spectral resolution and modulation detection, the improvement in higher modulation frequency discrimination might be particularly important for CI users in noisy environments. Sumario Objetivos: (1) Investigar si la discriminacióón de voz por géénero (VGD) puede ser un indicador úútil de las habilidades de procesamiento espectral y temporal de usuarios de implantes cocleares (IC); (2) Examinar la relacióón entre VGD y el reconocimiento del lenguaje con IC, cuando se usan claves acúústicas comparables para ambos procesos de percepcióón. Diseñño: Se midióó el VGD usando dos series de hablantes con diferentes frecuencias fundamentales (Fo) inter-géénero asíí como diferentes simulaciones acúústicas de IC. El reconocimiento de vocales y consonantes en silencio y con ruido tambiéén se midióó y comparóó con el rendimiento VGD. Muestra: Once usuarios sordos de IC post-lingüüíísticos. Resultados: Los resultados mostraron que 1) el rendimiento promedio VGD difirióó para diferentes grupos de estíímulos; 2) el rendimiento para el reconocimiento de VGD y de lenguaje varióó entre usuarios de IC y 3) el rendimiento individual de VGD correlacionóó significativamente con el reconocimiento del lenguaje bajo ciertas condiciones. Conclusiones: El VGD medido con grupos seleccionados de estíímulos puede ser úútil para evaluar no solamente la percepcióón relacionada con la frecuencia sino tambiéén el procesamiento espectral y temporal en usuarios de IC. Ademáás de la mejoríía en la resolucióón espectral y en la deteccióón de la modulacióón, la mejoríía en la discriminacióón en frecuencias de alta modulacióón puede ser particularmente importante para los usuarios de IC en ambientes de ruido.
