2

Choose model & voice

Pick one of 4 Gemini TTS models, then a voice from a searchable, filterable 30-voice library.

Generate & manage

Every clip is saved to History, playable, downloadable, editable, deletable.

🧠 Step 1 · Choose

Four Real Gemini TTS Models, Not One Fixed Voice EngineModel picker, confirmed live in the product

Rather than locking every generation to a single TTS engine, Spark Station exposes four real Gemini text-to-speech models side by side, so a quick greeting clip and a longer narration pass don't have to use the same tradeoffs.

🎙️ Step 2 · Cast a voice

30 Named Voices, Searchable and Previewable"Choose a Voice" modal, 14 Female, 16 Male, verified end to end

The voice picker isn't a short generic list, it's a real 30-voice library, each with its own name, gender tag and a ▶ preview you can play before committing. A search box and All / Female / Male filter pills make picking the right voice for a given script fast even at this size.

🎬 Step 3 · Direct

Direct the Delivery, Type the LanguageStyle Instructions + 6 quick presets, free-text Language field

A single "read this in an accent" toggle doesn't cover how differently a documentary narration, an ad read and a bedtime-story tone need to land. Style Instructions is a plain free-text field, the account's own saved default reads "Read aloud in a warm, welcoming tone", with 6 quick-start presets sitting right below it: Measured, Ad Voice, Documentary, News Anchor, Casual, ASMR.

Language works the same way: instead of scrolling a short fixed dropdown, it's a free-text field with live autocomplete, typing "a" surfaces "Arabic," confirming the field matches against a broad underlying language list rather than a handful of defaults. English (US) is the starting value.

Why it works better

Most TTS tools give you one voice knob. This gives you four.

A generic single-model TTS tool trades model, voice, style and language against each other, pick one setting and the others move to match. This one exposes all four independently.

✕ Generic single-model TTS
  • One voice engine, so tone control means picking from a handful of presets baked into that engine
  • A short, fixed language dropdown that stops at the "major" languages
  • No independent style-direction layer, the voice you pick is the tone you get
  • Clips often aren't saved anywhere searchable, re-generating means re-typing everything
✓ Spark Station AI Voice Generation
  • 4 real Gemini TTS models, chosen independently of voice
  • 30 named voices, searchable and filterable by gender, each previewable first
  • Style Instructions as free text or a quick preset, layered on top of, not baked into, the voice
  • Every clip saved to History with its transcript, ready to replay, edit or regenerate
