摘要： In one configuration, erasure of a significant frame of a sustained voiced segment is detected. An adaptive codebook gain value for the erased frame is calculated based on the preceding frame. If the calculated value is less than (alternatively, not greater than) a threshold value, a higher adaptive codebook gain value is used for the erased frame. The higher value may be derived from the calculated value or selected from among one or more predefined values.

摘要翻译： 在一种配置中，检测到持续浊音段的有效帧的擦除。 基于前一帧计算已擦除帧的自适应码本增益值。 如果计算值小于（或者不大于）阈值，则较高的自适应码本增益值被用于被擦除的帧。 较高的值可以从计算值导出或从一个或多个预定义值中选择。
