Create an instant voice clone by providing a sample audio file via file upload.
The cloned voice will be based on the characteristics of the provided audio
file. Upload the file using multipart/form-data and include the sample 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.
