Abstract
A method of operating a wireless device in an environment with ambient noise is disclosed. The wireless device includes a microphone and is configured to operate in both a voice mode and a non-voice mode such as text mode. In operation, the wireless device receives an indication of an attempted incoming call. Prior to causing the wireless device to generate a user-perceptible indication of the incoming call, the device determines whether an ambient noise parameter exceeds a predetermined threshold based on an ambient noise volume received by the microphone. When the ambient noise parameter exceeds the predetermined threshold, the wireless device switches to text mode and sends an indication that the wireless device is operating in text mode to the wireless service. The wireless device is operated in the voice mode when the ambient noise does not exceed the predetermined threshold.
