METHOD OF OPERATING A BARGE-IN DIALOGUE SYSTEM

摘要

A method is described for multi-user operation of a barge-in dialogue system (1). The dialogue system comprises a front-end computer unit (2) with a plurality of access channels (6) for the users and a plurality of servers (18, 19, 20, 21) having each a number of speech processing units (22). Each of the speech processing units (22) comprises a speech activity detector (23) and a speech recognition unit (24). During a dialogue between the system and a user, a new speech processing unit (22) is repeatedly assigned at various specific times to the user-deployed access channel (6) so as to achieve as uniform a utilization of the servers (18, 19, 20, 21) as possible. The speech activity detector (23) detects an incoming speech signal on the access channel (6) to which channel the speech processing unit (22) is assigned at this time, and activates the speech recognition unit (24). In addition, a corresponding barge-in dialogue system (1) is described.
