Abstract
Se presenta un sistema y método de procesamiento de voz. En una modalidad de la presente invencion, el sistema incluye al menos una unidad (elemento 21) de análisis de impulsos multiples de cuantificacion de probabilidad máxima (MLQ) que opera en un vector objetivo (elemento 26). La unidad de análisis de impulsos multiples MLQ determina normalmente un nivel de ganancia inicial para la secuencia de impulsos multiples y ejecuta un análisis de impulsos multiples de gananciaunica (MPA) varias veces, cada uno con un nivel diferente de ganancia. La secuencia de impulsos que representa en forma más cercana al vector objetivo se suministra como una señal de salida (elemento 38). En otra modalidad, el sistema incluye al menos una unidad de análisis de impulsos multiples de tren de impulsos en donde el vector objetivo se modela como una serie de trenes de impulsos. Cada tren de impulsos comprende una pluralidad de impulsos de ganancia unica, en donde cada impulso está en posicion que es una distancia del valor de paso separado de impulso previo en el tren de impulsos. Las combinaciones del análisis de probabilidad máxima con los trenes de impulsos también son parte de la presente invencion.
