About

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.
