Anyone building voice AI agents knows how hard it is to stay up-to-date with the latest text-to-speech voice models.

We spend time testing and experimenting with all of the available paid and open-source text-to-speech voice AI models and consolidated our own notes and experience testing different models into a single guide for developers evaluating multiple models.

Real-time voice AI is young, and the tools and infrastructure that will power its future are being built right now.

After working with and speaking to hundreds of teams building voice AI agents, we ve learned a lot.

We ve just shipped some big updates to the Layercode private beta:

Redesigned Dashboard UI

We're excited to announce a major upgrade to Layercode: support for Deepgram Flux: the world's first transcription system built specifically for voice agents.
