Table to Tablet (T2T): A Novel Intervention Framework for Children With Speech Sound Disorders

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Diagnose of Phonologically based Speech and Sound Disorder;
  • Portuguese as native language;
  • Audition of 20 decibels (dB) or lower in the frequencies 500, 1000, 2000 and 4000;

Treatment and study plan

Table-based T2T intervention

Other

Phonological therapy consists of a combination of phonological awareness activities, auditory and discrimination and auditory bombardment activities. This activities will be based on table top materials. The items used in the intervention will be based on the child's target speech production goals. This intervention will include the following areas:

  • Auditory Bombardment;
  • Auditory and discrimination;
  • Letter-sound knowledge;
  • Phoneme identity and phoneme matching;
  • Blending;
  • Segmentation;
  • Rhyme;
  • Phoneme manipulation.

Tablet-based T2T intervention

Other

Phonological therapy consists of a combination of phonological awareness activities, auditory and discrimination and auditory bombardment activities. This activities will be based on digital materials presented on a tablet. The items used in the intervention will be based on the child's target speech production goals. This intervention will include the following areas:

  • Auditory Bombardment;
  • Auditory and discrimination;
  • Letter-sound knowledge;
  • Phoneme identity and phoneme matching;
  • Blending;
  • Segmentation;
  • Rhyme;
  • Phoneme manipulation.
