Seed Audio

Seed Audio is a hosted AI text-to-speech and voice generator that turns scripts into natural, expressive speech for videos, podcasts, and apps. Paste your text, choose a voice, and generate lifelike narration in seconds—without downloading models or setting up GPUs. Use the same in-browser voice studio to switch between text to speech, instant voice cloning, and voice design.

Seed Audio’s main workflow starts with writing or pasting your script, then picking from a library of voices. If you want a consistent “signature” speaker, you can also create instant voice clones from a short consented sample and reuse that private voice across projects. For additional control, voice design lets you tune how a new or cloned voice sounds by adjusting elements like emotion, speed, and emphasis while you preview and iterate.

It’s designed for creators and teams who need fast revisions—regenerating changed lines without re-recording—as well as developers who want low-latency speech generation via an API. You can export or stream output, and generation history plus speech-to-text options help you refine results.

Seed Audio uses a credit-based pricing model. Free accounts generate up to 120 characters per conversion and signing in provides 15 welcome credits. Paid plans are annual and include shared credits for text to speech, voice design, and voice cloning, with a maximum of 1,000 characters per conversion. Annual plans listed include Basic ($4.95/month billed yearly) with 960,000 TTS characters/year and 9,600 voice credits; Pro ($14.95/month billed yearly) with 4,200,000 TTS characters/year and 42,000 voice credits; and Enterprise ($24.95/month billed yearly) with 9,600,000 TTS characters/year and 96,000 voice credits.

Can I try Seed Audio without creating an account?

Yes—you can use the in-browser voice studio to generate audio. Free plan limits still apply per conversion.

What are the character limits for generating audio?

Free accounts support a maximum of 120 characters per conversion. Paid plans raise this limit to 1,000 characters per conversion.

What is instant voice cloning, and what do I need for it?

Instant voice cloning recreates a consented speaker as a private voice model using a short consented sample. The clone is available in your account for reuse.

Can I design voices instead of only selecting from the voice library?

Yes. Seed Audio includes voice design controls that let you tune how a voice sounds, including emotion, speed, and emphasis, while generating and previewing audio.

Which languages are supported for text to speech?

Seed Audio supports speech in dozens of languages and accents. You can generate multilingual output from the same editor by selecting the appropriate voices.

Does Seed Audio offer an API for developers?

Yes. You can call the Seed Audio API to add speech to apps, assistants, IVR, games, and accessibility features, with low-latency generation.
