About AI training and TTS work

AI training (also called data labeling or data annotation) is the human side of building machine intelligence. For text-to-speech (TTS), people record natural voice examples and follow precise guidelines so models learn clarity, tone, pacing, and emotional range.

This role puts you on the cutting edge of voice AI: your recordings will help shape how conversational and expressive synthetic Spanish voices sound in real products.
