Kore (firm, clear) and Puck (upbeat, lively) are the recommended pair for long-form content. The other 11 — Charon, Zephyr, Fenrir, Leda, Orus, Aoede, Enceladus, Despina, Algieba, Achernar, Sulafat — cover everything from movie-trailer voiceover to meditation guides. Click ▶ on any voice to hear a sample before you generate.
ElevenLabs is $5–22/month with character caps. Murf.ai is $19–66/month. ViralMint charges $0.12 per 1,000 characters via Google Gemini 3.1 Flash TTS — a 60-second narration is about 10 cents. No minimum monthly spend, no commitment.
The desktop app also includes Edge TTS — Microsoft's free engine with 400+ voices across 100+ languages. Useful for non-English voiceovers or when you want zero cost on long-form content. Both engines feed the same Smart Video pipeline.
Download the free ViralMint desktop app (macOS / Windows / Linux) and open the Voice tool. The voice picker shows all 13 voices with inline play buttons — click ▶ on each card to preview the voice before committing.
Cards default to Kore (firm, clear) and Puck (upbeat, lively) — the recommended pair for creators. Up to 50,000 characters per generation. The character counter shows estimated cost at $0.12 per 1,000 characters.
Add a short style cue like 'warm and conversational' or 'fast-paced and energetic' to nudge the delivery. The model honors instructions like emphasis, pacing and tone.
Click Generate. The mp3 is ready in 3–10 seconds and starts playing in the result panel. Click Download mp3 to save it locally — or jump to the Library tab to find it later (saved 30 days).

Kore and Puck are the two recommended voices for natural narration. Kore is firm and clear, Puck is upbeat and lively — most creators pick one as a default and use the others for character work or alternate styles. Click the play button on each voice card to hear a 5-second sample before you commit.
Registered accounts get a small daily free allowance that covers light TTS usage. Beyond that, you pay per generation — typically a fraction of a cent for a short clip. The desktop app also bundles Edge TTS (Microsoft's free engine) for fully unlimited voiceover at the cost of slightly less natural delivery on some voices.
Yes. The TTS license permits commercial use of the generated audio. ViralMint adds no extra restriction — the mp3 you download is yours to use in YouTube videos, TikTok, podcasts, ads, courses, anything.
The script goes through ViralMint's cloud handler to the Gemini 3.1 Flash TTS API. The generated mp3 is stored in your Library for 30 days so you can re-download it; after that the bytes are deleted. We don't keep training data and we don't share scripts with anyone.
Up to 50,000 characters per generation — about a 50-minute narration. For longer scripts, split them into chunks; the desktop app's Smart Video pipeline does this automatically when generating videos longer than the per-call limit.
Yes — the ViralMint desktop app is a free download for macOS, Windows, and Linux, and it bundles Microsoft's Edge TTS engine: 400+ voices across 100+ languages at zero cost, with no character cap and no watermark. The premium Gemini 3.1 Flash TTS voices (Kore, Puck, and 11 more) are available pay-per-character at $0.12 per 1,000 characters with no subscription. So you get a genuinely free, downloadable AI voice generator, plus optional higher-fidelity voices when you want them.
The AI Voice Generator ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
