Speech practice for people with Parkinson's.

A'ber is a speech practice companion for people with Parkinson's disease. Short daily exercises for loudness, clarity, pitch and pace, with recording-quality checks and feedback compared with your own earlier sessions on the same phone. Exercise difficulty adapts to how your practice attempts go. It is not a medical device.

The four hallmarks of Parkinson's speech

Parkinson's related speech changes follow a recognizable pattern. Loudness drops below the patient's own intended volume even when they perceive themselves as speaking at normal intensity. Articulation becomes imprecise, particularly on the alveolar and velar consonants. Pitch flattens into monopitch with reduced semitone variation. Rate becomes irregular, often accelerating into a festinating cluster mid sentence. A'ber tracks your practice (loudness change when cued, pitch range, pace) against your own earlier sessions on the same phone. If you notice changes in your speech, talk to a healthcare professional.

How A'ber relates to LSVT LOUD

LSVT LOUD is an intensive programme delivered by trained clinicians. A'ber is not a substitute for LSVT LOUD or for care from a speech-language pathologist. It supports practice between SLP visits, with recording-quality checks after each recording. No comparative study against LSVT LOUD has been run.

What a Parkinson's session looks like

A typical A'ber session for a patient with Parkinson's opens with a two minute warm up sequence: postural reset, neck rolls, lip trills, and a sustained hum. The patient then completes a loudness drill set to their current practice level, an articulation drill on target words, an intonation glide, and a connected speech read of a short passage. The session closes with a short summary of the practice that was done.
