Abstract: A system and method include processing multiple individual participant speech in a conference call with an audio speech recognition system to create a transcript for each participant, assembling the transcripts into a single transcript having participant identification for each speaker in the single transcript, and making the transcript searchable. In one embodiment, encoder states are dynamically tracked and the state of each encoder is continuously tracked to allow interchange of state between encoders without creating audio artifacts, and re-initializing an encoder during a brief period of natural silence for encoders whose states continuously diverge. In yet a further embodiment, tracking of how each of multiple users has joined a conference call is performed to determine and utilize different messaging mechanisms for users.
