Abstract

The paper describes a new technique that enhances the voice activity detection (VAD) performance between the remote speaker (received signal) and the local speaker (located in the vehicle) in the context of mobile radio telephone environment. We use an auditory pitch and voiced/unvoiced detection (APD) algorithm in conjunction with an autoregressive (AR) analysis in order to remove the remote speaker´s voice signal from the car hands-free microphone signal. The results are compared with a reference system that doesn´t include the APD
