Create voice

client.Audio.Voices.New(ctx, body) (*Voice, error)
POST/audio/voices

Creates a voice from a text prompt or from a consent recording and an audio sample.

For prompt-based creation, send type: "prompt" with a name and prompt as JSON or multipart form data. For creation from an audio sample, send type: "audio_sample" with a name, audio_sample, and consent recording ID as multipart form data. The type defaults to audio_sample when omitted.
