Speech endpoint Detection __ speech recognition

1. Based on energy double threshold VAD

Operating platform: low power consumption

There is a problem: can not take into account false alarm and leak alarm, especially in the noise environment

2. Based on energy four threshold VAD

Operating platform: high power consumption

The performance is better than the double threshold vad, but there are some false alarm and leak alarm in the noise environment.

3. Fusion of energy VAD and model VAD

Firstly, the energy four-threshold VAD are first judged, and then the model VAD is confirmed.

Operating platform: high power consumption

There is a problem: can solve a part of false alarm, but unable to solve the energy VAD leakage alarm problem.
