Method and device for activating a voice-controlled function in a multi-station network through using both speaker-dependent and speaker-independent speech recognition

A method for activating a voice-controlled function in a multi-station network by using both speaker-dependent and speaker-independent speech recognition facilities, and conditionally to recognizing one or more items of an applicable vocabulary, driving one or more network parts to activate said function,

• characterized in that said method comprises the following steps:
• receiving a station-initiated call containing one or more speech items from the vocabulary;
• executing speaker-independent recognition on said speech items through one or more general templates, whilst in an improvement procedure, in case of successful ascertaining of what had been spoken actually, storing a particular template derived from the speech item so recognized and assigned to an origin of the call in question;
• following said improvement procedure, applying speaker-dependent recognition if feasible for speech received from the same origin, through one or more particular templates associated to that origin;
• whilst maintaining a fallback procedure to speaker-independent recognition for any particular origin in order to cater for inability of said speaker-dependent recognition, whilst allowing reverting to said improvement procedure.
