Abstract

La presente invención se refiere a un método para procesar una señal acústica vocal de entrada, para la extracción de pronunciaciones o modos de hablar individuales, que comprende las etapas de; a) convertir la señal vocal en una primera y una segunda secuencia de muestras vocales relacionadas, b) correlacionar la primera secuencia de muestras, vocales relacionadas para derivar un primer histograma que representa la señal vocal de entrada; c) correlacionar la segunda secuencia de muestras vocales relacionadas para segunda secuencia de muestras vocales relacionadas para derivar un segundo histograma que representa la señal vocal de entrada, d) comprimir el primer y segundo histogramas para derivar una pluralidad de canales espaciados, e) generar un histograma de compresión que representa al menos una parte de la señal vocal de entrada a partir de los canales espaciados; f) repetir las etapas a) a (e) para generar una secuencia de histogramas de compresión representando una transferencia de la señal dvocal de entrada g) identificar puntos terminales para cada pronunciación en la secuencia de los histogramas de compresión; y h) extraer pronunciaciones individuales de la secuencia de los histogramas de compresión entre las partes terminales de pronunciación identificadas.
