D Speech Signal Processing

consisted of seven Ph.D. students (five of whom were located at the department), a part-time (20%) researcher (forskarassistent), two guest researchers, and a professor. The group performs research encompassed within speech processing, signal processing, and source coding and teaches two undergraduate courses (Information Theory and Source Coding, and Digital Speech Signal Processing), in addition to a varying number of graduate courses. The group also supervises numerous 5-month projects performed by undergraduate students. The research of the group is mostly aimed towards improved algorithms for speech and audio coding, speech synthesis, and speech enhancement for various applications. In general, research in these areas has made great strides in the last few decades and the results of this labor are now part of everyday life. Speech coding is an enabling technology for mobile telephones. Audio coding is becoming commonplace in consumer electronic devices. Speech synthesis is often used in tele-communication services and speech enhancement is used for communications in adverse environments. Despite these recent advances, increasing quality and lowering bit rate remain important challenges for the future. New communication network technologies have introduced fresh challenges such as wideband speech coding, voice and audio over the Internet D SPEECH SIGNAL PROCESSING
