Clone a voice from an audio sample to create a custom voice for speech generation.
Prerequisites: API key, audio sample (MP3, WAV, or PCM format)
1

Clone the Voice

Upload your audio file directly using multipart/form-data. See the Clone Voice endpoint for details.
import requests

# Upload audio file directly
with open('voice_sample.mp3', 'rb') as f:
    files = {'file': ('voice_sample.mp3', f, 'audio/mpeg')}
    data = {
        'name': 'My Cloned Voice',
        'voice_visibility': 'PRIVATE',
        'language': 'en'  # Language code (en, es, fr, de, it, pt, pl, ru, nl, sv, ca)
    }
    response = requests.post(
        'https://dev.voice.ai/api/v1/tts/clone-voice',
        headers={'Authorization': 'Bearer YOUR_API_KEY'},
        files=files,
        data=data
    )

data = response.json()
print(f"Voice ID: {data['voice_id']}, Status: {data['status']}")
2

Check Voice Status

Check the voice status using the voice_id from the clone response. See the Get Voice endpoint for details.
import requests
import time

voice_id = data['voice_id']  # From clone response

# Poll until voice is available
while True:
    response = requests.get(
        f'https://dev.voice.ai/api/v1/tts/voice/{voice_id}',
        headers={'Authorization': 'Bearer YOUR_API_KEY'}
    )
    status_data = response.json()
    status = status_data['status']
    print(f"Status: {status}")
    
    if status == 'AVAILABLE':
        print("Voice is ready!")
        break
    elif status == 'FAILED':
        print("Voice cloning failed")
        break
    
    time.sleep(2)  # Wait 2 seconds before checking again
Status values:
  • PENDING - Voice cloning has started
  • PROCESSING - Voice is being processed
  • AVAILABLE - Voice is ready to use
  • FAILED - Voice cloning failed
