An apparatus ( ) checks voice quality when in a vocoder bypass mode. If the voice quality level is beyond an acceptable range, the apparatus ( ) ends the vocoder bypass mode and returns to tandem vocoding. For example, a vocoder bypass controller ( ) includes a speech quality detector ( ) 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 ( ) with the speech quality detector ( ) outputs a speech quality-based vocoder bypass control signal ( ) to selectively activate or deactivate a vocoder bypass operation in response to the speech quality-based vocoder bypass control signal ( ). In another embodiment, a network element for communicating speech packets includes an incoming decoder ( ) and a speech quality detector ( ) operative to determine the speech quality level of incoming speech packets. The speech quality detector ( ) determines whether to activate speech quality enhancement operations in response to a determined speech quality level of incoming speech packets.
