Create an instant voice clone by providing an URL for a sample audio file.
The cloned voice will be based on the characteristics of the provided audio file. Make the request using multipart/form-data and include a URL to the audio file. The created voice clone can be used for text-to-speech (TTS) generation.
The audio file selected as the source for the voice clone should have a duration ranging from 2 seconds to 1 hour. It can be in any audio format, as long as it falls within the size range of 5kb to 50MB.
