Abstract	:	This project was designed to improve the inclusive nature of courses on language learning and teaching through the creation of Adaptive English Phonetic tools (ADEPT) to provide better access to the International Phonetic Alphabet (IPA) symbols and the sounds they represent for blind and low vision learner and teachers of American English as a second or foreign language. This approach involved the integration of auditory and tactual information to facilitate the development of phonological literacy based on the effectiveness of multisensory training protocols. ADEPT consists of sets of tactile IPA symbol cards, and a companion website based on the Universal Design for Learning framework. Each IPA symbol card includes the symbol, its typographical description, and a reference number associated with the website (all with corresponding Braille notations). The website includes printed and audio-recorded information on the articulation of American English consonants and vowels with recordings of each sound in isolation and in sample words. The pedagogical efficacy of these tools was tested with 21 adult learners of English in Colombia with a focus on vowel production. A pretest-posttest design involving the delayed repetition technique was used. Learners’ productions of short sentences with multiple exemplars of American English vowels were audio-recorded. Native-speaker ratings revealed a significant improvement in learners’ pronunciation after 10 weeks of instruction. Qualitative data included pre- and post-study interviews and the researcher’s instructional notes. Learners described the auditory-tactual approach as “invaluable”. Field testing of the symbol cards indicated that they should be 3D printed for sustainability. In sum, ADEPT can facilitate a collaborative learning environment for sighted and non-sighted individuals.
