ABSTRACT:
A method is disclosed for identifying corrupted speech signals in a call receiving mode of a voice messaging system. The method includes the step of receiving a message signal. The message signal represents an audio message. The method next includes the step of determining a signal quality. The signal quality is then compared to a threshold. If the signal quality is at least as great as the threshold, the audio data representing the message signal is stored in a memory. If the signal quality is not as great as the threshold, an indication signal is transmitted indicating that the signal quality is poor. A system is also disclosed for implementing the steps of the method.
