Description copied from interface: KSService

This method starts the process of keyword spotting The audio data of the passed AudioStream is passed to the keyword spotting engine. The keyword spotting attempts to spot keyword as being spoken in the passed Locale. Spotted keyword is indicated by fired KSEvent events targeting the passed KSListener. The passed AudioStream must be of a supported AudioFormat. In other words an AudioFormat compatible with one returned from the getSupportedFormats() method. The passed Locale must be supported. That is to say it must be a Locale returned from the getSupportedLocales() method. The passed keyword is the keyword which should be spotted. The method is supposed to return fast, i.e. it should only start the spotting as a background process.
