Assistive Design for English Phonetic Tools (ADEPT) was developed to improve inclusion in classrooms and enhance collaboration among blind, low vision, and sighted learners of American English (AE) as a second/foreign language through better access to the International Phonetic Alphabet (IPA) symbols and the sounds they represent. Grounded in multisensory training efficacy, ADEPT involves auditory-visual- tactual integration through the use of visual-tactile IPA symbol cards and an auditory-visual companion website based on the Universal Design for Learning guidelines. Each card includes a symbol, description, and website reference number, all with braille notations. The website includes printed and audio-recorded information on the articulation of AE consonants and vowels, with recordings of each sound in isolation, syllables, and words. ADEPT’s pedagogical efficacy was field tested with 21 blind/low vision adult L2 learners of AE (L1 Spanish), emphasizing vowel production in a pretest-training-posttest design, which had a training period of 10 weeks. Production scores from native-speaking raters were the dependent variable in a multilevel model with time (pretest-posttest comparison) as a fixed effect. Results showed a significant effect of time (i.e., improvement in production accuracy); the fit of the model improved when the random effect of participants was added (p < .001). In addition, pre- and post-study comments were very positive. ADEPT, which learners described as “invaluable,” can facilitate a collaborative learning environment.
