2. Voice Cloning API

Clone any voice from a reference audio file:

from mlx_audio.tts.utils import load_model
from mlx_audio.tts.generate import generate_audio

# Load model (auto-downloads on first run, ~3GB)
model = load_model('mlx-community/Qwen3-TTS-12Hz-1.7B-Base-8bit')

# Generate cloned voice
generate_audio(
    model=model,
    text="Your text content here, supports long-form generation",
    ref_audio="path/to/reference_audio.wav",  # 10-30 second voice sample
    lang_code="zh",                          # zh, en, ja, ko, etc.
    file_prefix="output_filename",           # Output: output_filename_000.wav
    max_tokens=3000                          # Prevent audio truncation
)

3. Built-in Voice Templates

Generate speech without reference audio using pre-built voices:

from mlx_audio.tts.utils import load_model

model = load_model('mlx-community/Qwen3-TTS-12Hz-1.7B-Base-8bit')

# Generate speech with built-in voice template
results = list(model.generate(
    text='Hello world, this is a text-to-speech test',
    voice='af_heart',      # Voice template code
    language='Chinese'     # Language
))

# Save audio file
with open('output.wav', 'wb') as f:
    for result in results:
        f.write(result.audio)

🎵 Built-in Voice Templates

📝 Best Practices

Reference Audio Preparation

1. Duration: 10-30 seconds of clear human speech
2. Format: WAV format, mono, 16kHz/24kHz
3. Environment: Quiet room, no background noise
4. Content: Natural conversational speech, avoid extreme emotions

Quality Optimization

# Recommended parameters for best quality
generate_audio(
    model=model,
    text="Your text here",
    ref_audio="reference.wav",
    lang_code="zh",
    file_prefix="output",
    max_tokens=3000,        # Increase for longer text
    temperature=0.8,        # Diversity control (0.5-1.0)
    repetition_penalty=1.1  # Reduce repetition
)

Batch Generation

# Batch processing example
texts = [
    "First paragraph text",
    "Second paragraph text",
    "Third paragraph text",
]

for i, text in enumerate(texts):
    generate_audio(
        model=model,
        text=text,
        ref_audio="reference_audio.wav",
        lang_code="zh",
        file_prefix=f"batch_{i:03d}",
        max_tokens=3000
    )
    print(f"Generated: batch_{i:03d}_000.wav")

🔧 Troubleshooting

Common Issues

Q: Audio gets truncated?

# Increase max_tokens parameter
generate_audio(..., max_tokens=5000)

Q: Slow model download?

# Use Hugging Face mirror
export HF_ENDPOINT=https://hf-mirror.com
python3.10 your_script.py

Q: Poor cloning quality?

• Ensure reference audio is clear with no background noise
• Optimal reference duration: 15-25 seconds
• Try different reference audio recordings
• Match text style to reference voice style

Q: Python version issues?

# Verify Python 3.10 path
which python3.10
/opt/homebrew/bin/python3.10  # Confirm path

# Use full path to call
/opt/homebrew/bin/python3.10 your_script.py
