Abstract: A voice interactive service system provides different speech-based services to a plurality of users. Using a communication terminal, the services are accessed via a telecommunication network through service-specific connectivity ports. The system comprises processing cores which have different configurations of speech processing resources for performing different services. For performing a requested service, a connection module establishes a connection between the respective connectivity port and a processing core having a configuration of speech processing resources suitable for performing the requested service. Because of the service-specific resourcing of cores, there is no need for requesting and allocating processing resources from external resource servers. Moreover, the port-dedicated resourcing of the cores ensures that a successful access to a connectivity port leads to a successful provision of the requested service.
