Please note: Lately, there have been many news articles alluding to my work with statements such as "From something as simple as the sound of your breath, Rita Singh, a researcher at Carnegie Mellon University's Language Technologies Institute, can pull information about what you look like and the room from where you are calling". This is absolutely not true. Breath can identify people, but deriving infomation about the environment is not possible (from breath alone) at the moment. Many news reports out there are not endorsed by me, and many statements that are claimed to be made by me, have indeed not been made by me. I am writing up papers on what can or cannot be done with voice. They will appear soon on this webpage.
