An AI voice generation platform from Hanabi AI. Built around text-to-speech (TTS) that turns text into natural-sounding audio, it bundles voice cloning from short samples, speech-to-text (STT), a voice changer, and a studio mode for story production into a single service. It supports over 30 languages and lets you search a large voice library to find one you like. Its core TTS model, OpenAudio S1, ranks near the top of TTS-Arena2, the leaderboard for speech synthesis quality, and the platform also offers a pay-as-you-go developer API through REST and various SDKs.
Key Features
- High-quality text-to-speech (TTS): TTS built on the flagship OpenAudio S1 model delivers natural delivery that has earned strong marks on TTS-Arena2. You can insert emotion and tone tags such as (cheerful) or (hesitating) directly into your text for fine-grained control over how lines are spoken
- Voice cloning from short samples: Create a cloned voice that reproduces the timbre and speaking style from a sample as short as 10–15 seconds. The voices you create can be used directly in TTS and story production
- Support for 30+ languages: Generate audio in Japanese, English, Chinese, and many other languages. The interface is also localized, making it approachable for non-English speakers
- A large, searchable voice library: Browse, preview, and pick from a wide range of community-shared voices. Even without creating a voice yourself, you can quickly find one that fits your project
- STT, voice changer, and studio features: Transcription, voice conversion, and a story-production studio for staging dialogue between multiple characters — the platform covers most audio work end to end
- Developer API and SDKs: A REST API and SDKs are available on a pay-as-you-go basis. API latency is low enough to embed in real-time voice agent use cases

Pros and Cons
✅ Pros
- Natural, high-quality audio from a model that ranks highly on TTS-Arena2
- Voice cloning from samples as short as 10–15 seconds
- TTS, cloning, STT, voice changer, and studio features all in one service
- A free plan to test quality, with paid tiers priced reasonably for voice AI
- Pay-as-you-go API and SDKs make it easy to build into your own apps and workflows
⚠️ Cons
- The free plan’s roughly 7 minutes per month is thin — a paid plan is close to mandatory for real work
- The credit system means you’ll need to estimate costs before mass-producing long-form content
- Voice cloning can infringe on rights if you replicate someone’s voice without consent, so ethical and legal care is required
- Fine-grained control such as emotion tags takes trial and error before you land on the result you intended
