Speech Recognition History
Speech recognition systems date as far as 1940, when the U.S department of defense sponsored the first academic pursuits in speech recognition, but the project was a failure.
In the late 1950's IBM started its research in this domain. The objective of this research was to arrive at a correlation between sounds and the words they represent.
At the 1964 world's Fair IBM demonstrated recognition of spoken digits.
In the late 1960's the department of defense funded again a new research initiative.
The research included Automatic Prototyping that allows computers to search out specific sounds and store them for comparison and analysis, and Dynamic Programming that recognizes conversational speech despite variation in rates of speech.
During this period, IBM pioneered a statistical approach to speech recognition that allows the system to improve its performance automatically, using powerful statistical logarithms adapted from information theory.
In 1984, IBM demonstrated the world's first 5000-word vocabulary speech recognition system with 95 percent accuracy, but it required a mainframe computer.
In 1987, due to intensive research efforts, the vocabulary was increased to 20,000 words and the hardware required is reduced to a single auxiliary card.
In 1989 customers began to test the technology, and in 1992 IBM introduced the first dictation system called IBM Speech Server Series.
IBM continued its efforts and in 1993 it launched the IBM Personal dictation system running on an IBM PC. The system takes a dictation at about 80 words per minute with 95 percent accuracy and it supported multiple languages.
The main achievement in 1993 is that the processing power needed to do speech recognition finally arrived in the form of personal computers that had that power.
In 1996 IBM introduced a new release of dictation system called VoiceType 3.0 which...
