Nov 23, 11:00 AM in ICT-411 "Speech Coding, Speech Interfaces and IoT - Opportunities and Challenges"
At Software Science Departmental seminar on Friday, Nov 23, 2018 at 11:00 AM Prof. Tom Bäckström (Aalto University, Finland) will talk about "Speech Coding, Speech Interfaces and IoT - Opportunities and Challenges".
The seminar will take place in ICT-411.
Recent speech and audio coding standards such as 3GPP Enhanced Voice Services match the foreseeable needs and requirements in transmission of speech and audio, when using current transmission infrastructure and applications. Trends in Internet-of-Things technology and development in personal digital assistants (PDAs) however begs us to consider future requirements for codecs. The opportunities and challenges are here summarized in three concepts: collaboration, unification and privacy. First, an increasing number of devices will in the future be speech-operated, whereby the ability to focus voice commands to a specific devices becomes essential. We therefore need methods which allows collaboration between devices, such that ambiguities can be resolved. Second, such collaboration can be achieved with a unified and standardized communication protocol between voice-operated devices. To achieve such collaboration protocols, we need to develop distributed speech coding technology for ad-hoc IoT networks. Finally however, collaboration will increase the demand for privacy protection in speech interfaces, whereby it is likely that technologies for supporting privacy and generating trust will be in high demand.
Tom Bäckström, DSc, is a professor of practice at Aalto University, Department of Signal Processing and Acoustics. He was a central contributor to recent speech and audio coding standards such as 3GPP EVS and MPEG USAC, and his research focuses on speech coding, modelling and related mathematical methods. Recently, he has extended his interests to distributed coding in multi-device environments, where in addition to efficiency, also privacy becomes an important issue.
