Replica Studios

Replica Studios (operated by Replica Media Pty Ltd) built AI voice, text-to-speech (TTS) and speech-to-speech (STS) technology for creators, game developers, and software teams. Its platform offered an AI Voice Library of 40+ expressive voices, Voice Lab for blending up to five voices into a custom character, and Voice Director for generating voice overs and dialogue. Developers integrated these capabilities through the Replica API v2 (OpenAPI 3.0.0) — a REST API supporting text-to-speech, speech-to-speech, and voice-listing operations, authenticated with API keys or Bearer JWTs minted at the /v2/auth endpoint. Replica Studios was a Techstars portfolio company. The company ceased operations on 2025-06-30; the marketing site now shows a farewell page and the api.replicastudios.com host no longer resolves, so this profile is a historical/discovery record captured from public documentation.

Replica Studios publishes 1 API on the APIs.io network. Tagged areas include Company, Voice, Text-to-Speech, Speech to Speech, and Artificial Intelligence.

Replica Studios’ developer surface includes documentation, API reference, getting-started guide, support, authentication, and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/replica-studios: open an issue to ask a question, or submit a pull request to add artifacts.
