TalkBox: a DIY communication board case study
Bibliographic record
Abstract
Purpose – The purpose of this paper is to present TalkBox, an affordable and open-source communication board for users with communication or speech disorders. Making and tinkering methods are combined with community engagement and participatory design to create a democratic and accessible approach to assistive technology design. Design/methodology/approach – The authors employed a community-engaged participatory design methodology where we incorporated input from stakeholders into the design of the interface. Close collaboration with our community partner allowed us to make informed decisions on different aspects of the design from sourcing of the material to testing the prototype. Findings – Through describing TalkBox, the paper presents a concrete example of how assistive technology can be designed and deployed more democratically, how collaborations between academia and community partners can be established, and how the design reflects different aspects of the methodology used. Originality/value – This paper explores the question of how can open-source technology and making methods contribute to the development of more affordable and inclusive designs through a concrete example.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
