This paper examines the interaction of the Lombard ...

This paper presents an ultra-low-power voice activity detection (VAD) system to discriminate speech from non-speech parts of audio signals. The proposed VAD uses level-crossing sampling for detection. useless samples in the signal are eliminated due activity-dependent nature this scheme. A 40 ms moving window with a 30 overlap is exploited as feature extraction block, within which output analog...
