Abstract
A wireless communication apparatus (100) and communication method provides an audio-based call connection operation. For example, one method includes receiving an incoming call message (108) and receiving an input audio answer signal (120), such as a user's voice, in response to the incoming call message (108). This method includes detecting an amplitude or characteristic of the input audio answer signal (120) and sending an answer call message (126) based on the detected amplitude level of the input audio answer signal (120). In another embodiment, the process includes storing the input audio answer signal (120) as preconnection audio information (304b) and subsequently sending the preconnection audio information (304b) as a post connection greeting. For example, a user saying the word “hello,” completes the call without any additional greeting required. In another embodiment, prestored audio greeting information, such as key word templates, is used to compare with the input audio answer signal (120) to determine whether to send the answer call message (126) to complete the call connection.
