Higgs Audio is a text-audio foundation model project from Boson AI providing code and weights for conversational text-to-speech with zero-shot voice cloning and prosody control. The repository now serves as the home for the legacy v2/v2.5 models, since Higgs Audio v3 is released separately as standalone weights and a hosted API.

Use cases

• generate natural speech from text
• clone a voice from a short audio sample
• build a conversational voice assistant with expressive TTS
• self-host a TTS model on GPU with streaming output
• control emotion and prosody inline in generated speech
• synthesize speech in many languages

When to choose

• you want open weights for expressive, conversational TTS you can self-host
• you need zero-shot voice cloning without fine-tuning
• you want multilingual speech generation with style control
• you're researching text-audio foundation models

When to avoid

• you want the latest Higgs Audio v3 model - use the separate v3 release or hosted API instead
• you need a commercial production license without negotiating with Boson AI
• you have no GPU and don't want to use the hosted API
• you need lightweight on-device TTS
