Project Title: Real-Time Visual Feedback for Speech Research and Teaching

Project Description: Vowels are difficult to research or learn in a new language because the differences between them can be very subtle.  When speakers can’t ‘hear’ a new vowel distinction, their auditory system can’t help them learn to produce the new sound.  I have designed software that provides real-time visual feedback that helps guide speakers by giving them visual information about their speech in real time as they produce it.  By allowing the visual system to help where the auditory system can’t be relied on, this new tool has the potential for high-impact applications in speech research, teaching, and in clinical work.
