About AI Speech Training

AI speech systems learn from carefully prepared audio and transcript data. Human contributors listen to recordings, correct text, align words with timestamps, and identify unclear segments so models can learn from accurate examples.

This work is fully remote and often flexible, making it possible to contribute part time around other commitments. Your language knowledge and attention to detail directly support the development of cutting-edge speech technology.
