But what about privacy when speaking to your devices?
One of the things that I have found using wearable computers and various devices is that there are times that you want privacy. Using voice recognition is difficult in a loud place filled with other conversations and most of the current systems are not the best at discriminating a voice, unless it is by the loudness. There are, in addition, times that I want to be able to interact with my computer privately without others being aware. For example, I might be working on business applications, wanting to call someone and keep the name private, or I might want to be making “notes” to my computer while interacting with another person.

All of these, IMHO, indicate that computer interaction can be by voice, but only for a small segment of the interaction that I want to have.

Speaking of Voice Recognition. Intel, Microsoft and other top technology companies form a group to develop speech-enabled software that will allow communication without pushing buttons. Elisa Batista reports from Mountain View, California. [Wired News]
