Vocalume

Make real phone calls and be understood — Vocalume speaks what you type in a clear, natural version of your own voice. For ALS, stroke, Parkinson's, CP and more.

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.
