Respeecher

Respeecher Space is a real-time text-to-speech API with streaming latency under 200ms, priced pay-as-you-go at $2 per 60,000 characters (roughly $2 per hour of audio), with a free trial and no subscription.

Speech-to-speech conversion sits alongside it: a recorded performance is rendered in another voice with the original timing and delivery intact, rather than synthesised from text. It is used for dubbing and localisation.

Voices are licensed from real people, with a published revenue share of at least 25% to voice talent. Output carries C2PA Content Credentials.
