History of voice recognitionNew Electronics reports that voice recognition technology surfaced in the 1950s with the development of "Audrey" by Bell Laboratories. The software could recognize digits from a single voice. In 1982, Kurzwell Applied Intelligence unveiled a commercial speech recognition system. Dragon Dictate was released in 1990 and its newer, faster and easier-to-operate model is used in PCs and Macs today.
How does voice recognition work?When you speak a dictated text message to your smartphone, it sends the data to a central server. From there it accesses its voice recognition software and database. The software analyzes your speech and breaks it down into small parts called phonemes. Next, the audio software in your smartphone can analyze its order and even context of how its used to figure out what you want.
As you may have noticed, Siri and other voice recognition programs don't always work perfectly, but when you speak clearly and slowly enough, it responds accurately. Your smartphone or computer is probably the most common way you’ve used voice recognition software, but other devices are already using the technology (or slated to soon).
