Abstract: An apparatus (200) checks voice quality when in a vocoder bypass mode. If the voice quality level is beyond an acceptable range, the apparatus (200) ends the vocoder bypass mode and returns to tandem vocoding. For example, a vocoder bypass controller (206) includes a speech quality detector (225) that determines the speech quality level of speech information based on at least one of detected volume level, echo level and noise level of the speech information. The vocoder bypass controller (206) with the speech quality detector (225) outputs a speech quality-based vocoder bypass control signal (236) to selectively activate or deactivate a vocoder bypass operation in response to the speech quality-based vocoder bypass control signal (236). In another embodiment, a network element for communicating speech packets includes an incoming decoder (512) and a speech quality detector (514) operative to determine the speech quality level of incoming speech packets. The speech quality detector (514) determines whether to activate speech quality enhancement operations in response to a determined speech quality level of incoming speech packets.

Abstract translation: 当声码器旁路模式时，装置（200）检查语音质量。 如果语音质量级别超出可接受范围，则装置（200）结束声码器旁路模式并返回到串联声码。 例如，声码器旁路控制器（206）包括语音质量检测器（225），其基于语音信息的检测音量，回声电平和噪声电平中的至少一个来确定语音信息的语音质量水平。 具有语音质量检测器（225）的声码器旁路控制器（206）输出基于语音质量的声码器旁路控制信号（236），以响应于基于语音质量的声码器旁路控制信号选择性地启动或停用声码器旁路操作（ 236）。
