A robust speech detection algorithm for speech activated hands-free applications

Abstract

This paper describes a novel noise robust speech detection algorithm that can operate reliably in severe car noisy conditions. High performance has been obtained with the following techniques: (1) noise suppression based on principal component analysis for pre-processing, (2) robust endpoint detection using dynamic parameters [1] and (3) speech verification… (More)
