Vocalume

Vocalume gives people with serious speech differences a clear voice — on real phone calls, in a natural version of their own.

For people living with ALS, cerebral palsy, stroke, Parkinson's, or severe dysarthria, being understood can be exhausting — and phone calls can be the hardest part. Vocalume speaks what you type or tap in a clear voice built from your own using Apple Personal Voice — in person, and now on real phone calls.

PHONE CALLS IN YOUR VOICE
- Call any US number. The person you call sees YOUR phone number, not a stranger's.
- Type mid-call, or tap a saved phrase, and the other person hears it in your clear voice.
- One tap switches to your real voice whenever you want — you are always in control of how you sound.
- Speakerphone comes on automatically, so you can read and type while you talk.

IN PERSON
- Speak mode: talk or type, and Vocalume says it aloud clearly.
- Quick phrases: your most-used sentences, one tap away.
- Calibration: read short passages and get an honest recognition-accuracy score.

YOUR VOICE
- Connect an Apple Personal Voice (created free on your device, about 15 minutes of reading) so Vocalume sounds like you.
- No Personal Voice? Choose a natural system voice and switch anytime.
- Adjustable speaking rate.

PRIVATE BY DESIGN
- Your Personal Voice model never leaves your device.
- Speech is processed transiently — never stored, never used for training.
- No account. No ads. No tracking.
- Your phone number is used only to verify your caller ID, so your calls show as you.

GETTING STARTED WITH CALLS
- Verify your number once (about 30 seconds) so your calls show your caller ID.
- Calling currently supports US phone numbers.

Vocalume is an accessibility and communication tool.
