Available English Voices
Compare 28 Kokoro voices + 9 Kyutai/Pocket for english with a fixed sample. Voice type, grade, and traits are catalog cues rather than a quality guarantee—use the same part of your real script before choosing one.
Kyutai voices run on Pocket TTS only (voice-cloning via hf://kyutai/tts-voices/…), not Kokoro.

OfflineTTS is optimized for macOS, providing fast, private, and high-quality AI speech synthesis directly in Safari, Chrome, and Edge on Mac. With Apple Silicon (M1, M2, M3, M4) hardware acceleration and WebGPU/WebAssembly, you can generate natural speech locally on your Mac with zero server latency.
Why use OfflineTTS on Mac?
- Apple Silicon acceleration: fast inference utilizing the Unified Memory Architecture of M-series chips
- Native browser workflow: runs in Safari 18+, Chrome, and Edge without installing Python, Docker, or command-line dependencies
- Complete confidentiality: drafts, personal journals, and enterprise documents never leave your Mac
- Studio audio export: export uncompressed WAV or compact MP3 files directly into Logic Pro, Final Cut Pro, or DaVinci Resolve
- No subscription fees: unlimited generation without per-character meters or monthly cloud bills
Optimized Mac setup:
- For maximum speed on Apple Silicon, use Google Chrome or Microsoft Edge with WebGPU enabled
- For battery efficiency, use Safari with WebAssembly inference
- First load downloads the model into the browser cache (~150MB–300MB); subsequent generations run completely offline
Optimized On-Device AI Voice Generation for macOS
OfflineTTS on macOS leverages WebGPU and multi-threaded WebAssembly to deliver rapid, private speech synthesis directly within Safari, Google Chrome, and Microsoft Edge. On Apple Silicon (M1 through M4), neural voice rendering benefits from unified memory architecture for near-instant playback.
No terminal commands, Python environments, or third-party extensions are needed. The browser downloads the model once to local cache, after which audio can be generated completely offline without network connectivity.
Seamless Integration with Mac Creative and Editorial Workflows
Generated speech can be exported directly as 24kHz studio-quality WAV or MP3 files, ready for immediate import into Final Cut Pro, Logic Pro, DaVinci Resolve, or podcast editing suites. Timestamps and SRT captions are also available for video subtitles.
Local execution ensures that confidential client voice-overs, internal corporate communications, and personal creative writing remain private on your Mac, satisfying strict data governance and privacy standards.

English Text to Speech — FAQ
Is English text to speech free?
Yes. OfflineTTS does not charge per character and requires no signup or API key. Audio synthesis runs in your browser with the engine you select.
Does English text to speech work offline?
Offline behavior depends on the selected engine and language. Supertonic, Piper, Kitten, Pocket TTS, and English Kokoro can synthesize locally after their model files download. Non-English Kokoro uses the OfflineTTS phonemization service before audio is generated on your device.
Is my English text data private?
Audio synthesis runs locally in your browser. Fully local-capable engine and language combinations keep the input on your device after model download. Non-English Kokoro sends plain text to the OfflineTTS phonemization service and receives pronunciation data before local synthesis.
