Sonantic

Sonantic was a London-based AI voice company that built hyper-realistic, emotionally expressive text-to-speech models for entertainment, gaming, and film. The company is best known for recreating Val Kilmer's voice for Top Gun: Maverick after he lost his speaking voice to throat cancer. Spotify acquired Sonantic in June 2022 for a reported 93 million euros, and the underlying TTS technology has since been folded into Spotify products, most visibly the Spotify AI DJ feature launched in 2023. As of 2026, Sonantic no longer operates as a standalone product or public API. This apis.yml entry exists as a historical and archival record of the company, its technology, and its acquisition.

Sonantic is profiled on the APIs.io network. Tagged areas include Voice, Text-to-Speech, Emotive AI, Acquired, and Spotify.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sonantic: open an issue to ask a question, or submit a pull request to add artifacts.
