Do you have a voice-command system in your car, like a system that let's you say "Play CD" and the CD starts - or you can speak a phone number and the car automatically dials it for you? Well guess what, ladies - it may not be able to understand you. That's because experts say the speech-recognition technology has a hard time understanding women's voices. Take, for example, one couple we read about. The husband loves the voice-command system. He says it's awesome, but his wife can't stand it. She compares the system to the wicked HAL 9000 computer in the movie, 2001: A Space Odyssey. That's because it doesn't do anything she asks. If she asks to make a phone call, it'll turn on the radio. Or it offers the telephone if she asks for directions. She ends up doing just about everything manually. So why doesn't it work? Because the female voice is higher pitched, and women often speak more quietly - both of which make it harder for the recognition software to understand commands. Also, most voice-recognition technology was designed around male drivers. Then later, it was tweaked to adjust for female drivers and those with heavy accents. So what's being done to fix this problem? Software developers are trying to make the process more natural, so that drivers feel like they're speaking to a passenger instead of shouting at their car. Ford Motor Company is at the forefront at correcting the accent and gender issues. For example, they collected 50 percent more female voice samples than male samples, which means their voice recognition computers almost always understand women.
