Hello everyone, I am a VAPI Pay-as-you-go user and I’m currently trying to link my own voice module in Vapi. Unfortunately, in the “Voices” section of my assistant I can’t select a custom voice. As far as I know, you have to do this with a request in the following format: curl -X PATCH https://api.vapi.ai/assistant/b791ac92-95e3-4a69-ae66-2d0f3c20b5c2 \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "voice": { "provider": "custom-voice", "server": { "url": "https://tts.senity.ai/synthesize", "credentialId": "your_credential_id_for_token_auth", "timeoutSeconds": 30 } } }' But unfortunately that doesn’t work — instead I now have no speaker selected and I only hear crackling. Am I doing something wrong, or is custom voice simply not supported for “pay-as-you-go” users?
