ULTRASOUND OVERLAY VIDEOS AND THEIR APPLICATION IN INDIGENOUS LANGUAGE LEARNING AND REVITALIZATION

摘要

In second language (L2) acquisition, learners make use of not only auditory but also visual information to acquire the speech sounds and patterns in a new language. With respect to the latter, ultrasound has been demonstrated to be an effective tool in L2 pronunciation learning for facilitating visualization of the articulatory processes involved in speech production [8, 10, 11, 12]. Safe, non-invasive, and versatile, ultrasound allows learners to directly observe their articulator movements (and compare them with those of an instructor or native speaker), allowing them to make articulatory adjustments to improve their pronunciation.
