They created a phonetic dictionary with the sounds of different word groups and then set to work on an algorithm to decipher a string of spoken words based on phonetic sound matches and the probability that someone would speak the words in that order. The Bakers' approach was based purely on statistical relationships, such as the probability that any two or three words would appear one after another in spoken English. Their approach differed from that of other speech researchers, most of whom were attempting to recognize spoken language by providing contextual information, such as the speaker's identity, what the speaker knew, and what the speaker might be trying to say, in addition to rules of English. There they began to work on natural speech recognition capabilities. Rockefeller had neither experts in speech understanding nor suitable computing power, and so the Bakers moved to Carnegie Mellon University (CMU), a prime contractor for DARPA's Speech Understanding Research program. James Baker saw the waveforms-and the problem of natural speech recognition-as an interesting pattern-recognition problem. There were not yet techniques that could sort through naturally spoken sentences. At the time, systems were in place for recognizing a few hundred words of discrete speech, provided the system was trained on the speaker and the speaker paused between words. As graduate students at Rockefeller University in 1970, they became interested in speech recognition while observing waveforms of speech on an oscilloscope. now owns and manufactures this product, Dragon Naturally Speaking.ĭragon Systems was founded in 1982 by James and Janet Baker to commercialize speech recognition technology. Along with (or bundled with) this introduction of sound to computers came an early form of speech recognition.Īnother company that was founded in 1982 and whose eventual product has become the overwhelming leader in the speech recognition market was Dragon Systems.

Covox brought digital sound (via The Voice Master, Sound Master and The Speech Thing) to the Commodore 64, Atari 400/800, and finally to the IBM PC in the mid ‘80s. The first company to launch a commercial product was Covox in 1982.

Please view the Speech Recognition Timeline to get a full view of its development. Like most emerging technologies, there were several competing research "camps", each working independently to develop speech recognition. It was not until the early 1980's when the technology reached the commercial market. Government (primarily by the Military and DARPA - Defense Advanced Research Project Agency). At that time, most research was funded and performed by Universities and the U.S. With the average CPU now above a Pentium III and RAM levels at 500 MB and up, accuracy levels have reached 95% and better with transcription speeds at over 160 words per minute.Īs mentioned above, the study of automatic speech recognition and transcription began in the 1936 with AT&T's Bell Labs. Ever since research of this technology began in 1936, the largest barriers to the speed and accuracy of speech & voice recognition were computer speed and power (or the lack thereof). The technology of Automatic Speech Recognition (ASR) and Transcription has progressed greatly over the past few years.

Among the earliest applications for speech & voice recognition were automated telephone systems and medical dictation software (for transcription). Speech and voice recognition enables “hands-free” control of various electronic devices-a particular boon to many disabled persons-and the automatic creation of “print-ready” dictation. Speech and vocie recognition refers to the ability of machines to respond to spoken commands. Please also view the Speech Recognition Timeline.
