Incluso después de más de 30 años, el libro de texto de 1978 Rabiner y Schafer sigue siendo uno de los más completos para la enseñanza de un curso de procesamiento del habla a nivel de postgrado de un semestre. El nuevo libro se las arregla para superar eso y es, sin duda representa una mejora con respecto a la antigua. Se duplica el contenido del clásico imprescindible, añade muchos nuevos desarrollos tecnológicos en los últimos años, y amplía las áreas de aplicación que han visto un enorme crecimiento en las últimas dos décadas. La inclusión de nuevos problemas y ejercicios de MATLAB, junto con muestras de voz del mundo real también facilita conveniente trampolín para el diseño de proyectos de clase en profundidad.
