Abstract: The disclosure relates to a voice-activated floor control mechanism that may be used in push-to-talk (PTT) communications. In particular, a client device may compare an ambient noise bitrate during an idle state in a PTT call to a threshold value that indicates normal background noise levels and trigger a floor request in response to the ambient noise bitrate during the idle state exceeding and remaining above the threshold value until a timer expires. Furthermore, the voice-activated floor control mechanism may adjust the timer value or other criteria used to trigger the floor request based on a conversational context associated with the PTT call, infer whether or not the floor request was intended, stream buffered audible frames in response to receiving a floor grant, and determine whether to release the floor grant, among other things.
