Features
Why Choose Sonicker for Voice Design
Stop settling for "close enough" voices. Design exactly what you hear in your head.
Text-to-Voice Creation
Can't find the right voice in any library? Describe exactly what you hear in your head — "a calm, authoritative woman in her 40s with a slight Irish accent" — and AI generates it instantly. No audio samples, no casting calls.
Unlimited Character Voices
Your visual novel has a grizzled detective, a bubbly teenager, and a menacing villain. Design each one with a text description — unique voices for every character, without hiring a single voice actor.
10 Languages, Native Quality
Need a warm Japanese narrator for your anime project? A French brand voice for your Paris launch? Design voices in English, Japanese, Korean, Chinese, Spanish, French, German, Russian, Italian, and Portuguese — each with native-quality pronunciation, not a translated accent.
Save & Reuse Your Voices
Spent time crafting the perfect brand voice? It's automatically saved to your library. Reuse it across 100 videos, 50 podcast episodes, or an entire course series — consistent voice, zero re-work.
Voice Design vs Voice Cloning
Two ways to create your perfect voice — pick the right tool for the job.
Use Cases
Voice Design for Every Creative Need
From game characters to brand voices — describe it, and AI creates it.
Game Development
40 NPCs, each needing a unique voice. Voice actors charge $50-300/hr and your script isn't even final yet. Design every character voice from a text description, iterate as the story evolves, and save the casting budget for your gold release.
Audiobook Narration
You've written a thriller but can't find a narrator who sounds dark enough, gravelly enough, urgent enough. Describe the exact voice in your head — genre, mood, pacing — and AI builds the narrator your story deserves. No $5,000 studio bill.
Brand Voice
Your brand published 120 videos last year — each with a slightly different voiceover style. Design one signature voice, save it to your library, and use it across every video, ad, and product demo. Consistent identity, zero coordination headaches.
Animation & Film
Your short film has a cast of 8 characters and a budget of zero for voice talent. Design each character's voice — the villain's cold whisper, the hero's confident warmth — and produce a fully voiced cut before you pitch to investors.
Podcast Production
Your true-crime podcast needs a co-host but your ideal voice doesn't belong to anyone you know. Design the perfect co-host or narrator voice — serious but approachable, the kind of voice listeners trust — without an awkward casting process.
Accessibility
Generic screen reader voices make users tune out. Design a warm, personalized voice for your app's accessibility layer — one that sounds like a real person, not a robot reading a manual. Your users with visual impairments deserve that.
Frequently Asked Questions About Voice Design
Everything you need to know about creating custom AI voices.
- What is AI voice design?
- Think of it like casting a character who doesn't exist yet. Instead of browsing a voice library or recording someone, you just describe what you want in plain text — "a warm British male, mid-30s, slightly raspy, speaks with calm authority" — and AI builds that voice from scratch. It's like having a voice actor factory that can create anyone you can describe.
- How is voice design different from voice cloning?
- Cloning is making a copy — you give us audio of a real voice and we replicate it. Design is more like invention — you describe a voice that doesn't exist and AI creates it from nothing. Cloning is great when you want your own voice or a specific person's. Design is for when you need something entirely new — game characters, brand voices, fictional narrators. Sonicker offers both, which is pretty rare.
- Is Sonicker voice design free?
- Yes! Voice Design is free for all signed-in users — no credit card needed. Sign up and you can start designing custom voices from text descriptions right away. Each generation costs credits, just like regular text-to-speech. You get free monthly credits, which is enough to try several designs.
- What makes a good voice description?
- The more specific, the better. Don't just say "female voice" — say "a confident woman in her late 20s, slight Australian accent, warm but professional, speaks at a moderate pace with a hint of smile in her voice." Include age, gender, accent, emotional quality, and pacing. Think about how you'd describe a character in a screenplay. We even have example descriptions in the tool to get you started.
- What languages are supported for voice design?
- Ten languages right now: English, Chinese, Japanese, Korean, French, Spanish, German, Russian, Italian, and Portuguese. The designed voices sound genuinely native in each language, not like an accent layered on top. So if you design a Japanese narrator, they'll sound like an actual Japanese speaker, with proper intonation and rhythm.
- Can I use designed voices commercially?
- Yes — full commercial rights on any paid plan. Use your designed voices in YouTube videos, games, podcasts, ads, apps, courses, whatever you're building. The voices are AI-generated and unique to you, so there are no likeness rights or royalty issues to worry about.
- Can I save and reuse a designed voice?
- Absolutely — every voice you design is automatically saved to your voice library. So if you spend time crafting the perfect brand narrator, you can reuse that exact voice across hundreds of future generations. No need to re-describe it every time. Think of your library as your personal voice cast.
- What AI technology powers voice design?
- We use the Qwen3 TTS Voice Design model — one of the most advanced voice generation systems available. It doesn't just map descriptions to presets. It actually synthesizes new vocal characteristics from your text, capturing nuances like breathiness, resonance, and emotional tone. The result sounds like a real person, not a voice preset with a filter on it.
