Abstract
A method for maintaining transmit audio quality under harsh environmental conditions, the method includes receiving audio signals into a microphone of a portable communication device and determining at least one parameter associated with the received audio signals. In accordance with an embodiment, the at least one parameter is compared with a received audio parameter threshold. When the at least one parameter falls outside of the received audio parameter threshold, the audio routing is switched from the microphone to the loudspeaker. Subsequent communication may revert back to the microphone or remain at the loudspeaker depending on monitored audio conditions.
