Hume AI Open-Sources TADA: The TTS Model That Can't Hallucinate

Hume AI has launched TADA — an open-source text-to-speech model under the MIT license that solves one of the industry's hardest problems: content hallucinations in audio.

What Makes TADA Special?

Traditional TTS models can add words, syllables, or sounds that don't exist in the input text. TADA is built from the ground up to guarantee zero content hallucinations — the model produces exactly what you give it, nothing more.

Technical specifications:

• RTF (Real-Time Factor): 0.09 — extremely fast (11x faster than real-time)
• 2048-token context window — handles up to 700 seconds of continuous speech
• MIT-licensed — completely free for commercial use
• Open source on GitHub

Why This Matters

For applications where accuracy is critical — legal documents, medical information, contract summaries via voice — content hallucinations are a dealbreaker. TADA fundamentally removes this risk.

For voice agent pipelines and TTS infrastructure, this is worth evaluating as a replacement or supplement to existing solutions — especially for high-volume scenarios where licensing costs are a factor.

What MIT License Means

Everything. You can use TADA in commercial products without royalties, without API dependency, and fully on-premises. Combined with the low RTF, this makes TADA a strong option for enterprises with strict privacy requirements.
