An AAC app for Parkinson's speech changes

When forming and delivering words is the hard part, a reply is one tap away.

Parkinson's often makes a voice quieter, less clear, or harder to summon on demand long before words are gone. Rejoin gives your replies back their timing: it listens alongside the conversation, has replies ready as the question ends, and speaks the one you tap in a voice that sounds like yours.

One thing to be clear about: Rejoin is not a voice amplifier. If your main difficulty is being heard rather than producing speech, a dedicated amplifier or a volume-feedback app may serve you better, and a speech-language pathologist can help you tell the difference. Rejoin helps when forming and delivering the words is the hard part.

Your own voice, banked while it is easy

Record Apple Personal Voice while speech is still comfortable and Rejoin speaks your replies in it, at the same clarity every time, however tired you are. It is free, built into iPhone and iPad, and takes one sitting. If your voice has already changed, Apple's short three-word phrase option and Rejoin's warm built-in voices are both there. How to set up Personal Voice.

Less effort on a tiring day

When speaking is slow or fatiguing, Rejoin+ offers three replies in your own style while the other person is still talking, so a conversation becomes a series of taps rather than an effort. Nothing is spoken without your tap.

Typing to speak, your sayings board, routines and Display mode work fully offline for the moments you would rather type. The AI suggestions need a connection.

Designed around tremor

Tell Rejoin during setup that tremor is part of the picture and it adapts: bigger targets, and steady taps that register when you lift your finger so brushes and shakes are ignored. Button size and high contrast are adjustable at any time under Me, then Comfort.

What is free

Speaking is free forever: typing to speak with your own voice, your sayings board, routines, Display mode and history, all working offline. Rejoin+ adds the AI layer that listens and drafts replies, for $12.99 a month or $99.99 a year with the first month free. That layer runs on a server, so it needs a connection. If a subscription lapses, Rejoin never goes silent.
