Speech interval detection method and system, and speech speed converting method and system using the speech interval detection method and system

摘要

When the transmission speed (voice speed) of the listener's voice is slow, the connection sequence generator 8 calculates the data length of the input voice, the output data length previously calculated by the conversion function related to the preset size factor, The data length of the actual output voice is always monitored and the connection order is determined so that the mismatch between them does not occur. The audio data and the connection data are connected so as not to omit the audio information by controlling the audio data connection unit 9. [ When the power of the input signal data is calculated to distinguish the voice section from the non-voice section, the power threshold is determined according to the maximum value of the power and the difference between the maximum value and the minimum value.
