Directivity

Speech directivity describes the angular dependence of acoustic radiation from a talker’s mouth and nostrils and diffraction about his or her body and chair (if seated). It is an essential physical aspect of communication affecting sounds and signals in acoustical environments, audio, and telecommunication systems. Because high-resolution, spherically comprehensive measurements of live, phonetically balanced speech have been unavailable in the past, the authors have undertaken research to produce and share such data for simulations of acoustical environments, optimizations of microphone placements, speech studies, and other applications. The measurements included three male and three female talkers who repeated phonetically balanced passages …

Communication Of Deaf People Based On Myoware Muscle Sensor, Mohamad Ataya

Research Opportunities for Engineering Undergraduates (ROEU) Program 2018-19

The current project aims to create a product that enhances communication of deaf people. The developed product has the following features:

• a muscle sensor that transcribes sign language into actual letters

• a voice detector that translates speech into actual words

• the ability to receive and send emergency alerts.
