An Adaptive Voice Activity Detection Algorithm
Voice Activity Detection (VAD) is a crucial step for speech processing, which detecting accuracy and speed directly affects the effect of subsequent processing. Some voice processing system based phone or in the indoor environment, which need simple and quick method of VAD, for these representative voice signal, this paper proposes a new algorithm which is adaptive and quick based on a major im...
متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
متن کاملThe Self-adaptive Voice Activity Detection Algorithm based on time- frequency Parameters
In order to solve the inferior performance and sad self-adaptive of the traditional voice activity detection algorithm in an environment with low Signal to Noise Ratio (SNR), a new self-adaptive voice activity detection algorithm based on time-frequency (TF) parameters is put forward. After introducing the time-domain log-energy and improved mel-scale log-energy, the new TF parameters are acqui...
متن کاملAn efficient voice activity detection algorithm by combining statistical model and energy detection
In this article, we present a new voice activity detection (VAD) algorithm that is based on statistical models and empirical rule-based energy detection algorithm. Specifically, it needs two steps to separate speech segments from background noise. For the first step, the VAD detects possible speech endpoints efficiently using the empirical rulebased energy detection algorithm. However, the poss...
متن کاملAdaptive Regularization Framework for Robust Voice Activity Detection
Traditional VAD algorithms work well under clean conditions, their performance however decreases drastically in noisy environments. We have investigated the tradeoff between false acceptance rate (FAR) and false rejection rate (FRR) in VAD with the consideration of noise reduction and speech distortion problem in speech enhancement, and proposed a regularization framework for noise reduction in...
