What you can make with AI voices

YouTube narration

Narrate shorts, documentaries, explainers. Kokoro handles long reads without seams; pair with the video tools to dub + caption.

Audiobooks & podcasts

Turn a blog post, transcript, or PDF into a listenable MP3. Toggle long-form stitching for chapter-scale output.

Ads & voiceovers

Pick Chatterbox for expressive reads. 30-second ad scripts cost ~150 tokens — a fraction of ElevenLabs-grade pricing.

Language learning

Hear any passage in native-sounding speech across 37 languages. Adjust speed 0.5×-2× to drill pronunciation.

Game dialogue

Prototype NPC dialogue with character voices. Dia handles multi-speaker scenes; pair emotion + pitch for villains and heroes.

Accessibility

Read-aloud for long articles, form fields, product copy. WAV export lands in any screen-reader pipeline.

Pick a character-style voice (robot, monster, narrator, cartoon) from the voice list, paste your script, and generate the character voice instantly.

Cartoon, monster, robot, villain, hero, fairy, narrator, wizard, and many more character voice styles across 174 total AI voices.

Yes — character voice audio is royalty-free for games, animations, YouTube, and commercial projects. All voice models are permissively licensed.

~100 tokens per sentence. Your free daily token pool covers dozens of character voice clips per day without any subscription.
