A group communication service receives user node communications from and distributes user node communications to members of a communication group. The communication group members comprise a plurality of user nodes. The group communication service then receives an audio transcription request from one or more of the plurality of user nodes. In response to receiving the request, group communication service launches a bot node member of the communication group configured to deliver transcribed content messages to one or more destination services. The group communication system then receives an audio content message from one or more of the plurality of user nodes and delivers a transcribed content message of the audio content message to the one or more destination services over the bot node member of the communication group.
