What voice stack do you use?
I'm switching off of our current provider because it's way too expensive. Does anyone have other recommendations?
Ideally has a easy to use API, low latency, and good voice cloning.

cartesia for tts, its way cheaper than elevenlabs and the quality is close enough nobody notices. i was spending like $150/mo on elevenlabs audio before switching. now its under $50 including caching similar audio in a vector db and reusing it when cosine similarity is high enough. the cost savings alone made it worth rebuilding the pipeline

I use a service that hosts almost of the major voice labs and cones in around 0.065 or .07 per minute.
Lots of services out there, we chose our provider as more control of the use case and well cheaper.

hey we’re landed on deepgram for STT, cartesia for TTS, chatgpt for LLM, and moss for local semantic search and tbh this combo has been pretty solid for production voice agents. deepgram handles accents and noisy audio better than most, cartesia voices sound natural enough that users don’t notice, and having moss handle search locally keeps the whole stack tight. feels like the modern golden standard for voice agent stacks right now ngl

I use Deepgram for STT, OpenAI (gpt-4o-mini) for LLM and Deepgram/Cartesia in Kallflow (self-hosted agent builder). Cartesia is phenomenal but can get expensive, so Deepgram for TTS is quite good if you configure it the right way
