Performance evaluation and comparison of G.729/AMR/fuzzy voiceactivity detectors

摘要

The paper proposes a performance evaluation and comparison ofnG.729, AMR, and fuzzy voice activity detection (FVAD) algorithms. Thencomparison was made using objective, psychoacoustic, and subjectivenparameters. A highly varied speech database was also set up to evaluatenthe extent to which VADs depend on language, the signal-to-noise ration(SNR), or the power level
