Methods, systems, and products measure health data related to a user. A spoken phrase is received and time-stamped. The user is identified from the spoken phrase. A window of time is determined from a semantic content of the spoken phrase. A sensor measurement is received and time-stamped. A difference in time between the time-stamped spoken phrase and the time-stamped sensor measurement is determined and compared to the window of time. When the difference in time is within the window of time, then the sensor measurement is associated with the user.
