Not Applicable

Completed

• Conditions: Speech Disorders
• Interventions: Other: Table-based T2T intervention; Other: Tablet-based T2T intervention

• Registration Number: NCT02490826
• Lead Sponsor: Aveiro University

Brief Summary

The primary aim of this study is to develop software as a tool in speech and language therapy for the treatment of children (Portuguese and English) with phonologically based Speech Sound Disorders (SSD). Further, this project aims to test the effectiveness of this approach with two groups of preschool and school aged children with phonologically based SSD, with one group consisting of European Portuguese (EP) speakers and one group of British English (BE) speakers. Performance across the two groups will be compared. The total duration of the project will be 30 month.

Detailed Description

The Table to Tablet (T2T) project aims to develop software as a tool in speech and language therapy for the treatment of children (Portuguese and English) with phonologically based Speech Sound Disorders (SSD). Further, this project aims to test the effectiveness of this approach with two groups of children aged between 3 years and 6 months and 6 years and 6 months with phonologically based Speech Sound Disorders (SSD).

One group consists of European Portuguese (EP) speakers and one group of British English (BE) speakers. Each group should include 20 children with the referred criteria and the performance across the two groups will be compared.

The total duration of the project will be 30 month (software development over the first 12 months and an intervention study during following 18 months).

The T2T team includes 3 Speech and Language Therapists and 3 engineers/researchers plus a designer that will develop the T2T material.

Arm && Interventions

Group	Intervention	Description
Table-based T2T intervention	Table-based T2T intervention	A combined phonological awareness therapy, listening and discrimination and auditory bombardment activities intervention will be applied. This will be based in a table top material version. The intervention will consist of 12 weekly sessions (individual) of 45 min in duration, divided into two blocks (6+6) without any breaks.
