Abstract
An apparatus for controling a device by sound commands includes a microphone for receiving the sound command, and a processor for analysing the received sound commands and for determining the number of space-separated words or other interrupted sounds in a received sound command. The processor measures the time of interruption between the received sounds and determines that the end of a word has occurred if the interruption is above a first predetermined time period, and that the end of a command has occurred if the interruption is above a second, higher, predetermined time period. A control system controls the device in accordance with the number of space-separated words in the received sound command.
