Third-party notices

Liforma uses third-party software and models. Product surfaces refer to Liforma capabilities (for example Liforma Text-to-Speech). This page retains licence texts where required for compliance.

Third-party speech model (OpenRAIL-M)

Portions of Liforma’s animation pipeline use a third-party model released under the BigScience Open RAIL-M License.

The full licence text is hosted on this site at /legal/third-party/openrail-m.

Use of that model (including via Liforma) is subject to the OpenRAIL-M use-based restrictions in Attachment A of that licence (for example: no unlawful use, no non-consensual impersonation, and machine-generated content disclosure where that licence requires it). See also Acceptable Use.

Speech training corpora (CC BY 4.0)

Some Liforma Text-to-Speech voices are derived from publicly licensed speech corpora. Those voices are adaptations of the licensed material. Required attribution is on this page.

Integrators embedding Liforma

Developers who only embed Liforma experiences and receive product output (speech and avatar sessions) are not required by Liforma to republish this OpenRAIL-M notice on their own sites. Liforma hosts the canonical notice here. If you redistribute model weights or expose the model as your own hosted service, separate licence obligations may apply — seek your own counsel.

Other notices

Additional open-source dependency licences may be added here as the public corpus grows. Runtime and package manifests remain the source of truth for npm dependency licences.
