Licences & credits
sōtem models are built on these open foundations, under the licences their authors published. Each is pinned to an exact revision, and none calls an outside AI provider. sōtem Khaleeji is ours, trained on sōtem Data Lab recordings.

Reference recordings behind the example clips
The example clips on the sōtem Voice pages were generated by sōtem V1 using a reference recording from an openly licensed dataset. The person in that recording has no connection with sōtem and does not endorse it.
