Speech endpoint detection is an important part of modern speech information processing technology. The success of endpoint detection directly improves the performance and quality of speech coding, speech recognition, speech synthesis and human interaction. The robustness and accuracy of the enhanced algorithms have always been hot topics for many scholars in the condition of low Signal to Noise Ratio (SNR) and complex noise. In this paper, we aim to provide an overview of the state-of-the-art in time domain, frequency domain, time-frequency domain and cepstrum domain for speech endpoint detection algorithms and to cast a glance at the challenges for future research. |
