Equitable access to speech practice for rural Australian children using the SayBananas! mobile game.

PURPOSE: To evaluate the effect, usage, and user-experience for SayBananas!, a Mario-style mobile game providing Australian children access to high-dose individualised speech therapy practice.

METHOD: Participants were 45 rural Australian children with speech sound disorders (SSD; 4;4-10;5 years) with internet access. This mixed-methods study involved: (a) recruitment, (b) eligibility screening, (c) questionnaire, (d) online pre-assessment, (e) SayBananas! intervention using motor learning principles (4 weeks, 10-15 target words), and (f) online post-assessment and interview. Usage and performance were automatically monitored.

RESULT: Most participants were highly engaged with SayBananas! completing a median of 44.71 trials/session (∼45% of the 100 trial/session target, range 7-194). After intervention, participants made significant gains on treated words and on formal assessment of percentage of consonants, vowels, and phonemes correct. There was no reliable change for parent-rated intelligibility or children's feelings about talking. The number of practice sessions was significantly correlated with percent change on treated words. On average, children rated the app as "happy/good/fun" providing detailed drawings of playing SayBananas!. Families provided high ratings of engagement, functionality, aesthetics, and quality.

CONCLUSION: SayBananas! is a viable and engaging solution for rural Australian children with SSD to gain access to equitable, cost-effective speech practice. The amount of app use was associated with amount of speech production improvement over a 4-week period.
