ElevenLabs is the leading platform for AI voice synthesis, offering both instant voice cloning from short samples and professional voice cloning with fine-tuned models. Its API enables seamless integration with avatar applications for text-to-speech and real-time voice generation.

ElevenLabs Cloning Options

API Integration

from elevenlabs import ElevenLabs

client = ElevenLabs(api_key="your_api_key")

# Generate speech with a cloned voice
audio = client.text_to_speech.convert(
    text="Hello, I am your AI avatar assistant.",
    voice_id="your_cloned_voice_id",
    model_id="eleven_multilingual_v2",
    voice_settings={
        "stability": 0.5,
        "similarity_boost": 0.8,
        "style": 0.3
    }
)

# Save audio file
with open("output.mp3", "wb") as f:
    for chunk in audio:
        f.write(chunk)

Voice Settings

• Stability (0-1) - Higher values produce more consistent output; lower values add more expressiveness and variation
• Similarity Boost (0-1) - Higher values make the output sound more like the original voice
• Style (0-1) - Controls how much the model amplifies the speaking style of the original voice
• Speaker Boost - Enhances voice clarity and similarity at the cost of slight latency increase

Streaming API for Real-Time

ElevenLabs supports WebSocket streaming for real-time text-to-speech, essential for interactive avatar applications. Text chunks are sent as they are generated (e.g., from an LLM), and audio is streamed back with minimal latency.
