Sensory Prediction Engine

The Sensory Prediction Engine is the word-prediction technology developed by Sensory App House. It powers the suggestions that appear as you type when Sensory Prediction is selected as your prediction mode in the Readable Editor.

What makes it different

The Sensory Prediction Engine adds a layer of phonetic understanding: it knows how letters and letter combinations sound, and it uses that to suggest words that sound like what you typed — even when the spelling is wrong.

Phonetic rules

The engine includes a comprehensive set of phonetic substitution rules covering the patterns most commonly involved in dyslexia-related spelling difficulties. Examples (illustrative — exact rule list to be confirmed):

ph ↔ f — "fone" suggests "phone"
silent letters — "nife" suggests "knife", "rite" suggests "write"
vowel substitution — "skreem" suggests "scream", "luv" suggests "love"
doubled consonants — "buble" suggests "bubble"
i/y substitution — "myte" suggests "might"
letter reversals — "girl" typed as "gril" still suggests "girl"

The rules are applied in combination — meaning a word with several spelling differences (e.g. "fizical" → "physical") can still be matched.

How to use the engine

The Sensory Prediction Engine is activated by switching to Sensory Prediction mode in the Editor's Prediction tab. From that point on, all prediction inside the Editor uses the engine.

As you type, suggestions appear in the prediction strip — typically a horizontal bar showing 3–5 suggestions ranked by relevance. Click a suggestion or use the function keys to accept it.

Frequently Asked Questions

What is the Sensory Prediction Engine?

The prediction technology that powers Sensory Prediction mode. It uses 65+ phonetic rules to suggest words that sound like what you typed — even when the spelling is wide of the mark. Designed specifically, particularly dyslexia.

How is it different from standard word prediction?

Standard prediction matches what you've typed character-by-character. The Sensory Prediction Engine adds phonetic understanding — it knows how letters sound, and uses that to suggest words that sound like what you typed. So 'fone' suggests 'phone', 'nife' suggests 'knife', and 'fizical' suggests 'physical'.

What are the three prediction modes?

Standard prediction (conventional letter-matching), Phonetic prediction (adds phonetic matching for dyslexic users), and Topic prediction (filters by topic vocabulary).

Does the engine learn from my writing?

Yes — it tracks which suggestions you accept and which you ignore, using this to rank future suggestions. Words you use frequently rise to the top. The learning data is stored locally in your user profile and is not shared.

How do I activate the Sensory Prediction Engine?

Open the Readable Editor, go to the Prediction tab, and switch from Windows 11 Prediction to Sensory Prediction. The engine is activated for all writing inside the Editor.
