A method and apparatus for determining the manner in which a processor-enabled device should produce sounds from data is described. The device ideally synthesizes sounds digitally, and reproduces pre-recorded sounds, together with an audible delivery thereof, a memory in which is stored a database of a plurality data at least some of which is in the form of text-based indicators, and one or more pre-recorded sounds. The device is further capable of repeatedly determining one or more physical conditions, e.g. current GPS location, which is compared with one or more reference values provided in memory such that a positive result of the comparison gives rise to an event requiring a sound to be produced by the device.
