The Signal Processing and Instrumentation lab focuses on research in the areas of speech and signal processing, biomedical signal processing & instrumentation, electronic instrumentation, and embedded system design. The following is a list of research problems being tackled by students in the lab. Vocal tract shape estimation from speech signal, Enhancement of electrolaryngeal speech using spectral subtraction, Multi-band frequency compression for hearing-impaired, Speech enhancement by modification of stop consonant landmarks, Speech transformation using multivariate polynomial modeling, Cardiac output monitoring using impedance cardiography, Diagnostic information from impedance cardiography.
