Adaptive speech rate conversion without extension of input data duration, using speech interval detection |
摘要 |
Frame power of an input signal is calculated to discriminate speech frame intervals from non-speech intervals, by thresholding current frame power using an adaptive speech-detection threshold based on the past maximum frame power value and the difference between past maximum and the minimum frame power values, adaptively updated using a predetermined number of frames prior to the current one.
