A digital speech\u2010training app has been developed that could serve as a cost\u2010effective means of providing accessible intervention to children with SSD.<\/jats:p>\n <\/jats:sec>\n \n Aims<\/jats:title>\n \n To evaluate whether self\u2010supervised home\u2010training with the app\n Pop2TalkNordic<\/jats:italic>\n can expedite more target\u2010like speech for children with SSD and to explore children's experiences of using the app.\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Procedures<\/jats:title>\n Four 4\u20136\u2010year\u2010old Swedish children with SSD participated in a single\u2010case experimental design study, with a multiple\u2010baseline across\u2010subjects design. The children's production of target error patterns was monitored during baseline and intervention phases, for trained and untrained stimulus words. Three weeks of self\u2010supervised training with the app, with an aspired frequency of 5 days a week, in 15\u2010min training sessions, served as the intervention. The children's app usage was tracked, and their production of target word stimuli was recorded via the app.<\/jats:p>\n <\/jats:sec>\n \n Outcomes and Results<\/jats:title>\n None of the children reached more target\u2010like production of targeted consonants as a result of the intervention. For two participants, slight improvement was observed on trained, but not untrained, word stimuli. In terms of user experiences, the children varied from liking the game a lot and finding it easy, to not liking the game much at all and finding it difficult.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Implications<\/jats:title>\n \n In its current form, and when delivered as a self\u2010supervised training\u2010activity over three weeks, training with\n Pop2TalkNordic<\/jats:italic>\n \u00a0is not sufficient to expedite more target\u2010like speech in children with SSD. More parental engagement in the children's training with the app, and changes in game design (e.g., highlighting phonological contrast and allowing playback of multiple exemplars of target word items), are suggested routes to achieve better outcomes.\n <\/jats:p>\n <\/jats:sec>\n \n WHAT THIS PAPER ADDS<\/jats:title>\n \n What is already known on this subject<\/jats:italic>\n \n \n To achieve high\u2010enough intervention dose, home\u2010training is often an important part of intervention for speech sound disorder (SSD). This is not always easy for families to attain, however, and digital speech training games may offer an attractive alternative or complement.<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n \n What this paper adds to existing knowledge<\/jats:italic>\n \n \n By tracking four children's usage and speech production over three weeks of playing a speech training game at home, the paper shows that the current version of the game and the implemented intervention delivery are not sufficient to promote more accurate production of targeted speech sounds.<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n \n What are the potential or actual clinical implications of this work?<\/jats:italic>\n \n \n Before recommending the speech training game for children with SSD, changes are recommended both with regard to the design of the game itself (e.g., refining the feedback provided in the game) and to the intervention delivery (e.g., increasing parental involvement).<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/1460-6984.70163","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T07:35:18Z","timestamp":1764660918000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Self\u2010Supervised App\u2010Based Speech Training for Children With Speech Sound Disorder\u2014A Single\u2010Case Experimental Design Study"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4745-3456","authenticated-orcid":false,"given":"Sofia","family":"Str\u00f6mbergsson","sequence":"first","affiliation":[{"name":"Division of Speech and Language Pathology, Department of Clinical Science, Intervention and Technology (CLINTEC) Karolinska Institutet Stockholm Sweden"},{"name":"Department of Neurology, Division of Speech and Language Pathology Danderyd Hospital Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ella","family":"Edlund","sequence":"additional","affiliation":[{"name":"Department of Neurology, Division of Speech and Language Pathology Danderyd Hospital Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Department of Neurology, Division of Speech and Language Pathology Danderyd Hospital Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2040-9834","authenticated-orcid":false,"given":"Nhan","family":"Phan","sequence":"additional","affiliation":[{"name":"Department of Information and Communications Engineering Aalto University Espoo Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5278-7974","authenticated-orcid":false,"given":"Mikko","family":"Kurimo","sequence":"additional","affiliation":[{"name":"Department of Information and Communications Engineering Aalto University Espoo Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"75","volume-title":"Interventions for Speech Sound Disorders in Children","author":"Baker E.","year":"2021"},{"key":"e_1_2_8_3_1","unstructured":"Baker E.
