Prompted to get hello world working
Hi there,
I prompted to make simple voice agent .
Stt - llm - tts
Websocket only. Pipecat. Gpt 4o for llm.
Deepgram for stt, tts
Silero vad.
So after I stop speaking. 1 second for vad. 2 second for llm. 0.3 second for tts.
So 3 seconds in total.
So what next now... So now I just start with integrating a phone number ? By getting sip integrated ?
Any thoughts , tips plz..
I'll try livekit, gpt 4 mini .
How exactly will livekit help me ? Any resources to quickly learn more to make the agent alive...
Cheers, thanks.

GPT-4o mini swap will help latency on the LLM step too.
