Abstract
Un sistema, método, y aparato para separar la señal de voz de un ambiente acústico ruidoso. El proceso de separación puede incluir filtración bidireccional, separación de fuente ciega, y supresor de ruido de sustracción espectral de entrada doble. Los canales de entrada pueden incluir dos micrófonos omnidireccionales cuya salida se procesa utilizando filtración de retraso de fase para formar formas de haz de voz y ruido. Además, las formas de haz pueden ser de frecuencia corregida. Los micrófonos omnidireccionales generan un canal que substancialmente es únicamente ruido, y otro canal que es una combinación de ruido y voz. Un algoritmo de separación de fuente ciega aumenta la separación direccional mediante técnicas estadísticas. La señal de ruido y la señal de voz se utilizan después para ajustar las características del proceso en un supresor de sustracción espectral de ruido de entrada doble (DINS - dual input noise spectral) para reducir sustancialmente o eliminar el componente de ruido. De esta manera, el ruido se elimina eficazmente de la señal de combinación para generar una señal de voz de buena calidad.
