Base Claim:
1. A multichannel avionics communication system, the system comprising: a software defined radio coupled to an antenna, where the software defined radio produces digitized audio data for a plurality of voice communication channels based on digital samples of radio frequency (RF) carrier signals received by the antenna; an audio panel device coupled to the software defined radio and at least one speaker, the audio panel device receiving the digitized audio data for the plurality of voice communication channels, wherein using the at least one speaker, the audio panel device audibly reproduces, from a first portion of the digitized audio data, voice communication received over a first channel of the plurality of voice communication channels, the first channel corresponding to a user selected tuned frequency; and a processor executing a trigger word speech recognition algorithm that receives the digitized audio data and processes at least a second channel of the plurality of voice communication channels from a second portion of the digitized audio data to detect a message containing a trigger word, the at least a second channel corresponding to a monitored frequency; wherein when the trigger word speech recognition algorithm detects a trigger word, a communication associated with the trigger word and received on the at least a second channel is stored into a memory and an alert is generated.
