Specifically, it describes a broadcast news transcription system, multimodal human-computer interface, neural-network-based HMM adaptation for noisy speech, online incremental speaker adaptation combined with automatic speaker-change detection, message-driven speech recognition and understanding, a Japanese national project on spontaneous speech corpus and processing technology, and speech summarization. For processing spontaneous speech, paradigm shift from speech recognition to understanding where underlying messages of the speaker are extracted will be indispensable, instead of transcribing all the spoken words. Building a large corpus of spontaneous speech to construct reliable acoustic and linguistic models is also crucial. Due principally to the technology of making computers smaller, more powerful and cheaper, the ubiquitous and wearable computing era is expected to come into being in the initial years of the 21st century. In such an environment, speech recognition will be widely used as one of the principal methods of human-computer interaction.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

The estimation of the power loss and junction temperature of semiconductor devices has become the major issue with the increase of the current density and high switching frequency of advanced power devices. The paper presents a partially coupled approach to evaluate the power loss and predict working temperature of switching devices. As an example IGBT PWM (pulse-width modulation) inverter is given to demonstrate the application of this approach. Based on the measurement of IGBTs dynamic characteristics, the estimation of power loss considering the junction temperature is introduced. Then the finite element analysis is used to accurate peak junction temperature prediction needed during dynamic operating conditions. In addition, the effect of switching frequencies during transient thermal response is investigated. The new approach developed can be used for accurate rating semiconductor devices or heat sink systems in power circuit design. Results comparison between proposed approach and commercial simulator shows that this approach is effective as a design step.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.

In this paper we propose a new model for stream ciphers which does not make use of LFSRs. Instead, our stream ciphers are based on a cascade of small substitution boxes (s-boxes). Like the RC4 stream cipher designed by Ron Rivest, the cascade stream cipher makes use of evolving s-boxes and pointers. However, instead of using one large s-box we employ a cascade of several small s-boxes. Two parameters of this family of stream ciphers are the size of the individual s-boxes and the length of the cascade. If we use n-bit s-boxes, then each output of the stream cipher is an n-bit block. By way of example, a cascade consisting of 16 2-bit s-boxes would have an effective key length which is adequate for most practical applications. The number of s-boxes in the cascade can be increased if we desire more security. Our studies to date indicate that the cascade cipher has good statistical properties. The new cascade stream cipher requires relatively little storage and executes efficiently in both hardware and software.","PeriodicalId":184523,"journal":{"name":"Canadian Conference on Electrical and Computer Engineering 2001.
