A voice-interactive docking station is provided for use with a portable computing device. The portable computing device includes at least one information management application and a corresponding database for storing the data associated with the information management application. The docking station generally includes a speech input device for receiving speech input, a speech recognizer for translating the speech input into voice command data, and an interface application for interacting with the applications residing on the portable computing device. In particular, the interface application, in response to voice command data, accesses the data associated with the information management application residing on the portable computing device. The docking station may further include a text-to-speech synthesizer for converting output data from the interface application into speech output data, and an audio system for generating audio output from the speech output data.
