LLM and TTS latency get's determined and logged at the start. It's around 220ms for the LLM returning the first synthesizable sentence fragment (depending on the length of the fragment, which is usually something between 3 and 10 words). Then around 80ms of TTS until the first audio chunk is delivered. STT with base.en you can neglect, it's under 5 ms, VAD same. Turn detection model also adds around 20 ms. I have zero clue if and how fast this runs on a Mac.
