​
Overview

TavusTransport enables your Pipecat bot to join the same virtual room as a Tavus avatar and human participants. The transport integrates with the Tavus platform to create conversational AI applications where a Tavus avatar provides synchronized video and audio output while your bot handles the conversation logic. When used, the Pipecat bot connects to a Daily room alongside the Tavus avatar and user. The bot receives audio input from participants, processes it through your pipeline, and sends TTS audio to the Tavus avatar for synchronized video rendering.
