AI Researcher, Voice Models
Freya, Istanbul, Istanbul, TR +1
The role
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.
What you will do
- Train and fine-tune speech-to-text models that hold up on telephone audio, noise, accents and code switching.
- Build text-to-speech models that sound human: natural prosody, correct question intonation, stable voices across long calls.
- Work on audio codecs and speech-language models that listen and speak in one system.
- Collect, clean and filter large speech datasets, and design the training curriculum.
- Run ablations that isolate one change. Report objective metrics and listening tests side by side.
