The zany engineers at Google (GOOG) have been putting a lot of work into creating software that simulates connected human brain cells capable of independently communicating with one another and learning without human input, Technology Review reports. This “virtual brain” is now “being put to work making Google’s products smarter, with speech recognition being the first service to benefit,” Technology Review writes. Vincent Vanhoucke, a Google speech-recognition developer, tells the publication that the “virtual brain” technology has produced “between 20 and 25 percent improvement” in the speech software’s ability to correctly identify words. Technology Review speculates that products such as Google’s self-driving cars and its Glass augmented-reality visor will benefit from the virtual brain technology in the future.
