A 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 کاملReal-time audio-visual voice activity detection for speech recognition in noisy environments
Voice activity detection (VAD) is one of the most critical issues on performance degradation of speech recognition in noisy environment applications. A real-time VAD was developed by using face parameters (eye and lip contours) as a front-end for the traditional speech and noise (audio) GMMbased method. Speech recognition performance of the audiovisual VAD is shown to be comparable with audio-o...
متن کاملVoice activity detection and speaker localization using audiovisual cues
This paper proposes a multimodal approach to distinguish silence from speech situations, and to identify the location of the active speaker in the latter case. In our approach, a video camera is used to track the faces of the participants, and a microphone array is used to estimate the Sound Source Location (SSL) using the Steered Response Power with the phase transform (SRP-PHAT) method. The a...
متن کاملAudiovisual speech source separation: a regularization method based on visual voice activity detection
Audio-visual speech source separation consists in mixing visual speech processing techniques (e.g. lip parameters tracking) with source separation methods to improve and/or simplify the extraction of a speech signal from a mixture of acoustic signals. In this paper, we present a new approach to this problem: visual information is used here as a voice activity detector (VAD). Results show that, ...
متن کاملBimodal Recurrent Neural Network for Audiovisual Voice Activity Detection
Voice activity detection (VAD) is an important preprocessing step in speech-based systems, especially for emerging handfree intelligent assistants. Conventional VAD systems relying on audio-only features are normally impaired by noise in the environment. An alternative approach to address this problem is audiovisual VAD (AV-VAD) systems. Modeling timing dependencies between acoustic and visual ...
