You will build voice models that are the best in the world for the languages and conditions we serve. That means 8 kHz telephone audio, noise, accents, people talking over each other, and answers that must come back in a few hundred milliseconds.
This is not a paper-only role. You take an idea to a training run, then to a model that serves live calls. You measure it on real traffic.
If you want to build the best voice models in the world and see them work on live calls, we want to hear from you.
We build the most realistic voice models in the world. Our English model, Freya TTS Adam V1, ranks #1 among AI models on Design Arena's Audio Realism Bench, behind only real human recordings: https://www.designarena.ai/leaderboard/audiorealismbench
We own the full voice stack: our own speech-to-text and text-to-speech models, LLM serving, and a real-time agent runtime. Our models run in production, often on-prem inside banks and insurers, and answer real customer calls every day.
