Frame synchronization fast wavelet packet algorithm is a FFT-like wavelet transform algorithm. In this paper, the analysis method of frame synchronization hybrid wavelet packet is proposed, which is characterized by the time-frequency analysis of wavelet transform, while the analysis of the time window can meet the requirement of frame length in speech processing, so that real-time processing can be realized. This hybrid wavelet packet has completely reconstructed characteristics. The experiment contrast shows the superiority of frame synchronization hybrid wavelet packet analysis.
