Performance evaluation and comparison of ITU-T/ETSI voice activity detectors

The paper proposes a performance evaluation and comparison of recent ITU-T and ETSI voice activity detection algorithms. The comparison was made using both objective and psychoacoustic parameters, so as to have reliable judgements that were close to subjective ones. A highly varied speech database was also set up to evaluate the extent to which VADs depend on language, the signal to noise ratio, or the power level.
