The development of an open software and hardware architecture speech processing system is important in order to expand and facilitate research in a wide range of acoustical work including speech processing, hearing aid development, hearing aid fitting, general psychoacoustics, noise cancellation, tinnitus, auditory evoked potentials and otoacoustic emissions. The proposed system will also provide speech processing students with a powerful tool to implement, develop and test novel processing ideas. As such, the proposed work will greatly impact public health by providing tools that will help address current research needs in these areas.
