note
Inference prefers matching person/org residency to nearby model hosting when ready — affinity, not a hard geo-fence. Dakar is the Senegal residency preference; Africa-west affinity pin remains af-west-1. Live serving for verbalab is jnb today; Senegalese French neural speech uses the optional shared Echo worker (no dedicated always-on Fly app). No Accra GPU island is deployed.

France French (fr-FR) and Ivorian French (fr-CI) are not interchangeable with Dakar Senegalese French — not the national default.

license_warnings

license_warnings: 4
  • Senegalese French MMS-TTS (facebook/mms-tts-fra) is CC-BY-NC-4.0 — unrestricted commercial redistribution of those assets is blocked.
  • Whisper ASR for Senegalese French corridor — pin versions and attribute per model card.
  • Dakar is the product default via prosody + labels on shared Senegalese French-general weights — not a Senegal-wide exclusive speech finetune, and not interchangeable with France French (fr-FR) or Ivorian French (fr-CI).
  • Phrase/lexical Baobab MT covers reviewed corridor domains; neural_nmt is false (no dedicated Senegalese French NLLB national service shipped).
