Scientists have pursued voice recognition for almost as long as they have been building computers.
![]() The Automatic Call Identification system enabled engineers anywhere in the US to talk to and receive spoken answers from a computer in Raleigh, NC. It was IBMs first speech recognition system to operate over telephone lines and respond to a range of different voices and accents. ![]() After all, if a machine has to move, it does it with wheelsnot by walking. If a machine has to fly, it does so as an airplane doesnot by flapping its wings. Rather than exhaustively studying how people listen to and understand speech, we wanted to find the natural way for the machine to do it. The community criticized the techniques as completely impractical for actual implementation. Jelinek took this as a challenge and embarked upon an ambitious plan resulting in the development of a voice-activated typewriter in the 1980s. ![]() Each speaker had to individually train the typewriter to recognize his or her voice, and pause briefly between each word. By the mid 1980s, Tangora boasted a 20,000-word vocabulary demonstrating the validity of the statistical approach. The journey would require leaps in processing power and reduced cost of computing. Nahamoo and many other IBMers paved the way for products such as the first packaged speech recognition product, the IBM Speech Server Series (1992), and the first large vocabulary continuous speech recognition product, the IBM MedSpeak product (1996) which would become more widely available as IBM. By the late 1990s, IBM had decided to focus on telephony and embedded offerings, such as IBM. These range from transcribing lectures and meetings to automatic closed-captioning of TV broadcasts. Watson read the written clues rather than heard them spoken, but drew on many of the same advancements in statistics and linguistics to make sense of the questions. In addition, Watson also spoke the answers, using speech synthesis technology developed by the IBM speech team that heavily leveraged statistical methodologies. He was not a pioneer of speech recognition, noted Steve Young, chair of the IEEE Speech and Language Processing Technical Committee.
