CAMB AI is a voice AI and localization platform trusted by brands like the Premier League, the NBA, NASCAR, and the Australian Open. We offer low-latency streaming TTS (~150ms with mars-flash), voice cloning, and translated TTS in 50+ languages, which is a natural fit for a language-learning podcast app like lingopod.
We'd love to be included as a TTS option. Happy to iterate on any feedback!
