What is Seed Audio AI?

Seed Audio AI is a browser-based text-to-speech workspace for turning written scripts into voice audio drafts. The workflow is to paste a script, choose a voice, adjust speed and delivery settings, generate, then preview, download as MP3 or share a link, with generation history available when signed in. The publisher names creators, marketers, educators, agencies and small teams as its users, for voiceovers, narration, podcast segments, audiobook drafts and ad reads.

Beyond preset voices, the product offers Voice Design for describing a reusable private voice and Voice Clone from reference audio, which the publisher says may only be used with audio the user owns or has clear permission to use. A separate Seed Audio 1.0 workspace generates layered scene audio from one prompt, combining multi-speaker dialogue, ambience, background music and effects, with optional audio or image references and a multilingual mode. Voices shown on the site include English, Chinese, Japanese, French and German options, and the publisher says a full voice library is coming.

The site also hosts six free music utilities: MP3 to MIDI, BPM and key detection, chord detection, a stem splitter, MIDI to audio and MIDI to sheet music. Users start with free audio credits (the amount is not stated); further generation is sold through yearly plans (Creator $99, Pro $249 and Studio $499 per year) or one-time credit packs from $19. The pricing page lists text-to-speech and standard Voice Design at about 100 credits per generated minute, and voice cloning and Seed Audio 1.0 generation at about 700 credits per minute; failed generations are not charged.

Seed Audio AI describes itself as an independent product that is not affiliated with ByteDance, Seed or Volcengine.

Pricing: Free credits to start; Creator $99/yr, Pro $249/yr, Studio $499/yr; one-time credit packs $19, $29 or $49; monthly billing also offered (prices not shown)

FAQs

Common questions about Seed Audio AI

Is Seed Audio AI free?
Partly. The site says users start with free audio credits, without stating an amount, and the six music utilities (MP3 to MIDI, BPM and key detection, chord detection, stem splitter, MIDI to audio, MIDI to sheet music) are listed as free. More voice generation requires a paid plan: yearly Creator $99, Pro $249 or Studio $499, or one-time credit packs of $19, $29 or $49. The pricing page also says monthly billing is available, but monthly prices are not shown in the page text.
How are Seed Audio AI credits charged?
The pricing page says credits are charged by generated audio duration: text-to-speech with preset voices and standard Voice Design use 100 credits per minute, while voice cloning and Seed Audio 1.0 scene generation use 700 credits per minute. The site's FAQs also say longer scripts consume more credits. Failed generations are not charged, and monthly plan credits are valid for 30 days.
Can Seed Audio AI clone a voice?
Yes. Voice Clone accepts reference audio, but the publisher says to use it only with audio the user owns or has clear authorization to use, and not to upload celebrity, public figure, private individual or other third-party voices without permission. Unauthorized voice use can be reported to support@seedaud.io.
Can generated audio be used commercially?
According to the publisher, commercial use depends on the plan, the Seed Audio AI Terms, applicable law and the user's rights in any scripts or voice references. Paid plans list commercial voiceover workflows where the plan and rights permit.
Who makes Seed Audio AI, and is it affiliated with ByteDance?
The site credits the Seed Audio AI Team and describes Seed Audio AI as an independent product that is not affiliated with ByteDance, Seed or Volcengine. Its Seed Audio 1.0 workspace is described as powered by ByteDance Seed's Seed Audio 1.0 model, while standard text-to-speech and Voice Design use SeedSpeech TTS v2.
What platforms does Seed Audio AI run on?
Seed Audio AI runs in a web browser with no install required. The site is available in English and Simplified Chinese.
