Abstract

The performance of speaker recognition systems may degrade significantly when speech is recorded in reverberant environments by a microphone positioned far from the speaker. Most of the literature on speaker recognition uses the reverberation time to classify the reverberation effects. However, as described in this work, the reverberation time is mainly a room feature and is less affected by the distance between the source and the microphone. This paper presents a comprehensive study of room acoustics parameters and their relationship with speaker recognition performance. The definition and centra-time, acoustic parameters which are affected by both room properties and distance, were found to be more correlated with the degradation in the speaker recognition performance.
