一种丢帧补偿方法及设备技术

一种丢帧补偿方法及设备，包括：接收语音码流序列；获取该语音码流序列中的历史帧信息以及未来帧信息，其中，该语音码流序列包括多个语音帧的帧信息，该多个语音帧包括至少一个历史帧、至少一个当前帧和至少一个未来帧，该至少一个历史帧在时域上位于至少一个当前帧之前，至少一个未来帧在时域上位于至少一个当前帧之后，该历史帧信息是该至少一个历史帧的帧信息，该未来帧信息是该至少一个未来帧的帧信息；根据该历史帧信息以及未来帧信息，估计该至少一个当前帧的帧信息，提高了丢帧补偿的准确度。

A Frame Loss Compensation Method and Equipment

A frame loss compensation method and device includes: receiving a voice stream sequence; acquiring historical frame information and future frame information in the voice stream sequence, in which the voice stream sequence includes frame information of multiple voice frames, which include at least one historical frame, at least one current frame and at least one future frame, and the at least one historical frame is located in the time domain. Before at least one current frame, at least one future frame is located after at least one current frame in the time domain, and the historical frame information is the frame information of the at least one historical frame, and the future frame information is the frame information of the at least one future frame. Based on the historical frame information and the future frame information, the frame information of the at least one current frame is estimated to improve the accuracy of frame loss compensation.
