AphaSay's Speak mode reconstructs the sentence you were trying to say. In peer-reviewed testing, GPT-4o reconstructed about 80% of aphasic utterances correctly — strong, but not perfect. Here's how to get the most out of it.
Why it sometimes misses
- ·Very few content words — "the" and "and" give the AI little to work with
- ·An unusual request the app has no context for
- ·Background noise drowning out the recording
- ·A topic that isn't in your profile
How to improve accuracy
- 1Fill out your profile as completely as you can — names, routine, home.
- 2Try to include the key nouns and verbs, even broken ones.
- 3Record somewhere quiet and hold the phone a comfortable distance away.
- 4Use the "Did you mean…" alternatives — picking one teaches the app your patterns.
When to use Quick Phrases instead
For things you say often — "I need the bathroom," "Please call my daughter," emergencies — a saved Quick Phrase is faster and 100% reliable. Reconstruction is for the open-ended things you can't predict.
