This Early-concept Grants for Exploratory Research (EAGER) funding project focuses on exploring and developing a novel operational collection of speech, language and perception-based measures to objectively assess speech intelligibility for second language (L2) speech production, as well as providing effective learner-specific feedback. With the rise of English as an international language, intelligibility-based successful communication has been emphasized over native-like accents. However, L2 teachers often raise concerns about learners’ slow or stagnant pronunciation progress. Several primary reasons for this problem may include difficulties in perceptually discerning changes in learners’ speech and interpreting learners’ speech patterns without any learner-specific intelligibility assessment profile. Today, teachers have no systematic way to assess each student’s speech changes, nor can students monitor and track feedback related to their pronunciation learning progression. Therefore, an exploratory and transformative method is introduced for measuring speech intelligibility that provides both teachers and learners with objective and individualized feedback. This exploratory project is proposed for EAGER funding in order to establish a baseline working framework for operational objective measure creation, and proof-of-concept assessment feedback for teachers and learners. This approach will help teachers gauge learners’ intelligibility levels and allow learners to self-regulate their learning progress incrementally over time. The long-term innovation is expected to benefit skilled US professionals from non-English speaking countries, who work in various STEM (science, technology, engineering, and mathematics) fields. Additionally, this interdisciplinary project provides various opportunities for hands-on training and experience for both graduate and undergraduate students in the fields of language education, applied linguistics, computer engineering, and speech technology.
