METHOD FOR IMPROVING SPEECH QUALITY IN SPEECH TRANSMISSION TASKS
Abstract:
The invention relates to a method for calculating the amplication factor, which co-determines the volume, for a speech signal transmitted in encoded form. Said speech signal is divided into short temporal signal segments. The individual signal segments are encoded and transmitted separately from each other, and the amplication factor for each signal segment is calculated, transmitted and used by the decoder to reconstruct the signal. The amplication factor is determined by minimizing the value E(g_opt2) = (1-a) *f>1 2
Abstract(Chinese):

本发明涉及一种方法，用于计算体积共同确定用于编码发送的语音信号，其中，所述语音信号被划分成时间短的信号部分，并且彼此独立地编码和发送的各个信号部分的增益因子，并计算放大因子的每一个信号部分，发射和从解码器到 所述信号的重建被使用，其中，所述增益通过最小化E（g_opt2）=（1-α）* F + F> 2的尺寸被确定> 1 <（g_opt2）的a * <（g_opt2），其中，所述加权因子的确定 考虑到发生时，周期性和编码的语音信号的平稳性两者。
