Replaced my custom stack with retell
So I was struggling with building a custom voice agent where I had everything from deepgram stt to twilio to elevenlabs tts but the latency was terrible and retell was wayyy more simpler and at the same cost

No longer will I use GHL
I've been using the GHL AI voice agent and there is no comparison. T'm thoroughly impressed with Retell's product and I will use it going forward. The voices are all so human-like that I can't tell the difference. Easy application as well...no hiccups at all. I certainly recommend that you use Retell for your AI voice agent needs.
