Apple's free accessibility feature lets you record your voice now, before potential loss. iPhone synthesizes a synthetic version that sounds like you — for use in Live Speech, FaceTime, and accessibility apps.
Apple Personal Voice (iOS 17+, iPadOS 17+, macOS Sonoma+) is a free accessibility feature that creates a synthesized version of your voice. You record 150 prompts (~30 minutes), iPhone trains a voice model overnight using on-device machine learning. The result: a synthetic voice that sounds like you, usable in Live Speech, FaceTime, and accessibility apps.
Apple's commitment:
| Situation | Why preserve voice now |
|---|---|
| ALS diagnosis | Average voice loss within 2-5 years. Critical to record while voice is strong. |
| Throat/vocal cord surgery | Some surgeries permanently alter voice. Record before surgery. |
| Cancer treatment | Radiation/surgery near vocal cords can damage voice. Preserve before treatment. |
| Parkinson\'s | Speech changes (hypokinetic dysarthria) over time. Earlier recording = better quality. |
| Legacy recording | Even healthy people: capture how you sound at this age. Recordings + voice for grandchildren. |
| Existing speech disability | Use Personal Voice as primary speech with Live Speech + AAC apps. |
Tip: Read with your normal energy. Don't whisper or shout. Pretend you're telling a friend a story.
The synthesized voice is impressively close — probably 80-90% recognizable as you. Family members usually identify it as "you" with mild robotic quality. Better than generic synthesizers (Siri, Alexa). Not perfect — emotion + inflection is limited.
Apple continues to improve the technology. Each iOS release improves voice quality. Voices recorded today will sound better as iOS updates.
Live Speech is the feature that uses Personal Voice. Type, iPhone speaks in your voice. Settings → Accessibility → Live Speech → ON.
