Estimulador Coclear: Prototipo de evaluación y emulación

En el presente trabajo se expone el diagrama en bloque de un diseño electrónico que permite emular el funcionamiento de un estimulador coclear o comúnmente conocido como implante coclear con fines investigativos. Dado a la versatilidad de su diseño permite emular y probar en tiempo real múltiples estrategias de estimulación coclear, tanto las actualmente conocidas (CIS, etc.) como cualquier variante nueva

Bioinspired Auditory Model for Vowel Recognition

In this work, a bioinspired or neuromorphic model to replicate the vowel recognition process for an auditory system is presented. A bioinspired peripheral and central auditory system model is implemented and a neuromorphic higher auditory system model based on artificial neuronal nets for vowel recognition is proposed. For their verification, ten Hispanic Spanish language-speaking adults (five males and five females) were used. With the proposed bioinspired model based on artificial neuronal nets it is possible to recognize with high levels of accuracy and sensibility the vowels phonemes of speech signals and the assessment of cochlear implant stimulation strategies in terms of vowel recognition
