What are AI Voice Models for LiveKit?

AI voice models are artificial intelligence models designed to generate, understand, recognize, and transform human speech using machine learning and advanced audio processing technologies. These models power capabilities such as text-to-speech (TTS), speech-to-text (STT), voice cloning, speech synthesis, voice conversion, real-time voice conversations, and multilingual speech generation. AI voice models often use neural networks, transformers, diffusion models, and multimodal architectures to produce natural-sounding speech with realistic intonation, emotion, pacing, and speaker characteristics. Many AI voice models are available through APIs, SDKs, open-source frameworks, and cloud platforms, enabling developers to integrate voice capabilities into AI assistants, conversational agents, contact centers, accessibility tools, media production workflows, and enterprise applications. By enabling natural, low-latency voice interactions and automating speech-related tasks, AI voice models help organizations create more accessible, engaging, and intelligent voice-powered experiences.

    Inworld TTS
    Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.

    Voxtral Mini Transcribe Realtime 3
    Voxtral Mini Transcribe Realtime 3 is a speech-to-text model delivered through Mistral’s API for applications that need live transcription. It streams audio over WebSocket and returns transcript events while a person is speaking, with configurable streaming delays. Developers can use it to add real-time captions, voice-assistant input, or transcription to voice-agent workflows. The model provides turn detection, speaker diarization, and context biasing for domain-specific vocabulary, and supports transcription across 45 languages and dialects. Applications can connect to its real-time endpoint and receive transcription events as audio arrives, rather than waiting for an entire recording to finish. Voxtral Mini Transcribe Realtime 3 is part of Mistral’s Voxtral audio model family.
