Novel Approaches to Speech Detection in the Processing of Continuous Audio Streams (original) (raw)

Open Access Database www.i-techonline.com Robust Speech Recognition and Understanding 24 a generic phoneme recognizer. We also propose the fusion of different selected representations in order to improve the speech-detection results. Section 3 describes the two SNS-segmentation approaches used in our evaluations, one of which was specially designed for the proposed feature representation. In the evaluation section we present results from a wide range of experiments on a BN audio database using different speech-processing applications. We try to assess the performance of the proposed representation using a comparison with existing approaches for two different tasks. In the first task the performance of different representations of the audio signals is assessed directly by comparing the evaluation results of speech and non-speech detection on BN audio data. The second group of experiments tries to determine the impact of SNS segmentation on the subsequent processing of the audio data. We then measure the impact of different SNSsegmentation systems when they are applied in a pre-processing step of an evaluated speaker-diarisation system that is used as a speaker-tracking tool for BN audio data.
