Once AxForge deploys f5-tts-vietnamese-vivoice for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (f5-tts-vietnamese-vivoice below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \ -H "Authorization: Bearer $AXFORGE_API_KEY" \ -F model="f5-tts-vietnamese-vivoice" -F file=@audio.mp3
