  • Abstract
    In this paper, a new paradigm for voice activity detection (VAD) is introduced. The idea is to exploit the spectral nature of speech to make independent voice activity decisions in separate sub-bands, resulting in multiple decisions for any frame. A potential method to perform multi-decision sub-band VAD is proposed then evaluated with a small test set. The evaluations illustrate the concept and potential benefit of multi-decision sub-band VAD.
