<p>A distributed speech recognition system (300) includes at least one client station (330) and a server station (310) connected via the public Internet (350). The client station (330) includes means (331) for receiving the speech input signal from a user. A speech controller (335) directs at least part of the speech input signal to a local speech recognizer (334). The, preferably limited, speech recognizer (334) is capable of recognizing at least part of the speech input, for instance a spoken command for starting full recognition. In dependence on the outcome of the recognition, the speech controller (335) selectively directs a part of the speech input signal via the public Internet (350) to the server station (310). The server station (310) includes means (312) for receiving the speech equivalent signal from the public Internet and a large/huge vocabulary speech recognizer (314) for recognizing the received speech equivalent signal.</p> |
