iTALKBetter will provide an app-based therapy for people with word retrieval difficulties who have had a stroke.
This study aims to test the therapy application for people with naming difficulties through a small scale randomized controlled trial.

Active Comparator: iTALKbetter: deterministic
Participants will receive the deterministic version of the iTALKbetter therapy for 6 weeks. Participants are required to use the therapy for 1.5 hours everyday to reach the required dose of 60 hours over the 6 week period.
iTALKbetter:deterministic version will randomise the order all of the words that are to be trained and participants will cycle through all of these words regardless of their performance until complete at which point the order is re-randomised and participants begin the cycle again.

Other Name: deterministic iTB
Active Comparator: iTALKbetter: reactive
Participants will receive the reactive version of the iTALKbetter therapy for 6 weeks. Participants are required to use the therapy for 1.5 hours everyday to reach the required dose of 60 hours over the 6 week period.
iTALKbetter reactive version is identical to the deterministic version for the first cycle only. From then on the words participants are trained on can change depending on their performance on that word over a number of cycles. Words that participants are failing to retrieve over a number of cycles will be retired from the therapy as they are deemed too difficult for a given participant. Similarly words that are correctly retrieved over a number of consecutive cycles are also retired from the therapy as they are deemed to have been learned. In this way iTALKbetter reactive version will gradually give each participant a personalised corpus of words that they can train on, focusing on the words where they stand to make the most improvements.

A word retrieval therapy application
- Change in accuracy performance on a bespoke Word Retrieval Test: WRT [ Time Frame: baseline (week 1), pre intervention (week 12), post-intervention (week 18) ]The WRT is custom test of word retrieval comprised of a subset of the trained and untrained items form the iTALKbetter therapy. Participants accuracy on the word retrieval test is measured at multiple timepoints (baseline, pre intervention, during intervention and post intervention).
- Patient and carer reported outcome measures [ Time Frame: pre intervention (week 12), post intervention (week 18) ]Qualitative semi-structured interviews to assess a variety of outcomes.
