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.
