Yes, there is no reason computer voices should not be programmed to sound like women. Male voices are deeper, and some people read men as more authoritative; however, there is nothing inherently wrong with the sound of a woman's voice. Women's voices have been used in devices like GPS for years without controversy. As long as users have different voices of various genders to select from, there is no reason the practice should not continue.
There is nothing wrong with programming computer voices to sound like women. Many computer voices sound like men as well. This decision is entirely up to the developer. Our society has become too politically correct - worrying about the gender of a computer voice. Anyone offended by the gender of the computer voice has lived a charmed life.
No, computer voices should be programmed to best suit the consumer. Whoever buys a product should be able to choose which voice he or she hears. There should be many different options to choose from. Different accents should also be available. Leave this decision up to the individual with the device.
Some people prefer having a computerized voice that sounds female, while others like a computer voice to sound more male. The early computerized voices were female, and that is what a lot of people are accustomed to, but modern computers should be programmed to sound like both sexes and people should have a choice.
