# Talk pipeline `pipeline.yaml` is runnable with a simulated audio chunk so the framework can be tested before the cmvr-es microphone stream proto is available. When the bidirectional audio RPC lands, replace the synthetic source with the typed `cmvr.grpc.microphone_audio_stream@1` connector and expand the chain to: ```text AudioChunk -> VAD -> ASR -> dialogue -> TTS -> speaker stream ``` The internal `AudioChunk/v1` contract and port/QoS model are already independent of the final protobuf message names.
