Venue: CSE Seminar Hall
Abstract:
The last few years have seen the prevalence of communication devices which allow multiple modes of interaction (POTS, mobile phones, PDAs, laptops). Several factors such as the need for interoperability,\Nadvances in natural language interfaces and standardization efforts (W3C, VoiceXML, SALT) have contributed to renewed interest in speech centric interfaces for voice and multimodal applications. Recent advances in speaker independent ASR engines, multilingual TTS and telephony have made it possible to demonstrate the feasibility of building sophisticated anytime-anywhere speech based applications (reporting, voice activated dialing, surveys, emergency notification etc.). In practice, several issues need to be addressed in order to make such applications easy to use, scaleable and reliable before they can be widely adopted. These include user interface design, authoring and processing tools, domain specific grammars, dictionaries, security and backend integration. In particular, when existing technologies for speech recognition are deployed for usage on both landline and mobile phones, the results are less than perfect. It is possible to build applications using innovative strategies that make best use of the existing\Ntechnologies,including:1. Employ knowledge of the problem domain to constrain the set of possible interpretations.2. Employ strategies to distinguish accurately sensed information from less accurate information.3. Combine contextual information with recognized information\Nto make more accurate decisions. I will describe some typical problems and approaches to solve the above issues in the context of real-world software applications. Time permitting, I shall also discuss some of my current interests and past work in hyperlinked video and video smoothing on the internet.
