V 43*50+* Zigital speech processing is a maCor field in current research all oAer the world. -n particular for automatic speech recognition [8?O\, Aery significant achieAements haAe been made since the first attempts of digit recogni]ers in the YU^G_s and YUXG_s when spectral resonances were determined by analogue filters and logical circuits. 8s "rof. Kurui pointed out in his reAiew on ^G years of automatic speech recognition at the WFnd -111 -nternational Monference on 8coustics, ?peech, and ?ignal "rocessing [-M8??"\, FGGH, we may now see speech recogni. tion systems in their W.^th generation. 8lthough there are many excellent systems for con. tinuous speech recognition, speech translation and information extraction, 8?O systems need to be improAed for spontaneous speech. Kurthermore, robustness under noisy condi. tions is still a goal that has not been achieAed entirely if distant microphones are used for speech input. The automated recognition of emotion is another aspect in Aoice.driAen sys. tems that has gained much importance in recent years. Kor natural language understanding in general, and for the correct interpretation of a speaDer_s recogni]ed words, such paralin. guistic information may be used to improAe future speech systems. This booD on Oobust ?peech Oecognition and Pnderstanding brings together many different aspects of the current research on automatic speech recognition and language understand. ing. The first four chapters address the tasD of Aoice actiAity detection which is considered an important issue for all speech recognition systems. The next chapters giAe seAeral exten. sions to state.of.the.art ‘QQ methods. Kurthermore, a number of chapters particularly ad. dress the tasD of robust 8?O under noisy conditions. Two chapters on the automatic recog. nition of a speaDer_s emotional state highlight the importance of natural speech understanding and interpretation in Aoice.driAen systems. The last chapters of the booD ad. dress the application of conAersational systems on robots, as well as the autonomous acaui. sition of Aocali]ation sDills. be want to express our thanDs to all authors who haAe contributed to this booD by the best of their scientific worD. be hope you enCoy reading this booD and get many helpful ideas for your own research or application of speech technology.
