VOICE ACTIVITY MODIFICATION FRAME ACQUIRING METHOD AND VOICE ACTIVITY DETECTION METHOD AND APPARATUS

摘要

According to the present invention, there is provided a method for acquiring a voice activation correction frame quantity, a voice activation detection method, and an apparatus. First, a first voice activation detection determination result is obtained, a voice activation maintenance frame quantity is acquired, and a number of background noise updates is obtained. The voice activation correction frame quantity is calculated according to the first voice activation detection determination result, the voice activation maintenance frame quantity and the background noise update count, and further, the second voice activation detection determination result is obtained. The voice activation detection determination result of the current frame is calculated based on the quantity and the second voice activation detection determination result.
