摘要
According to the invention, the type of transmission of signaling information, for a user-interaction with a speech dialogue system in a packet network, is determined with relation to a simplifying processing for DTMF signaling information. A speech dialogue system without special hardware for the processing of DTMF in-band signaling is provided and maintains, during the codec negotiation or the fixing of the coding method for application, that only services with DTMF out-of-band signaling, or signaling by means of dedicated data packets (for example RFC 2833) are carried out by the speech dialogue system. The above may be achieved whereby coding methods with in-band signaling are basically not permitted with relation to the codec negotiation or the control device, controlling the speech dialogue system, is embodied such that, independently of the coding method, out-of-band signaling is always stipulated by the control device. According to a further embodiment, an as a rule smaller-sized speech dialogue system is provided with hardware devices for the processing of DTMF in-band signaling for service requirements, for which out-of-band signaling or signaling by means of dedicated packets cannot be required. The efficiency of information output in packet networks and an economic resource application is thus achieved.
