Paradigms:
In the future voice recognition could make other forms of identification obsolete. It will surpass other forms of biometrics, such as fingerprinting and iris scans, as the technology is simpler.
Increased use of computers and internet will speed up the development of voice-recognition software.
Voice-recognition could make the keyboard and mouse obsolete.
Voice-recognition can be very helpful to various services in regions where there is a high illiteracy rate, as users do not have to type to activate the services. This could be used in banking, healthcare, public administrations etc.
Experts:
William S. Meisel, Ph.D., president of TMA Associates
Karen Livescu Ph.D., assistant professor Toyota Technical Institute Chicago
James R. Glass Ph.D., Principal Research Scientist at CSAIL
Timing:
1870 This technology really began with Alexander Graham Bell's inventions in the 1870s.
1952 Bell Communications Research started to investigate speech recognition with zero crossing
1959 Kyoto University, Japan, developed “speech-recognition typewriter” utilizing the technology Bell Communication research developed.
1964 IBM presents an early Speech recognition device, the IBM Shoebox, at the New York's World Fair
1970s Russia and Japan simultaneously developed DP matching method, which normalizes utterance time length by using dynamic programming
1980s Two distinct types of commercial products were available. The first offered speaker-independent recognition of small vocabularies. It was most useful for telephone transaction processing. The second, offered by Kurzweil Applied Intelligence, Dragon Systems, and IBM, focused on the development of large-vocabulary voice recognition systems so that text documents could be created by voice dictation.
1990s Defense Advanced Research Projects Agency, U.S, started dictation program for speech recognition, which realized Q&A voice recognition system by n-Gram method
