Evaluation of a voice interface management system Tattegrain-Veste, H et al

By: Tattegrain-Veste, HPublication details: Transportation Research Record, 2001Description: nr 1759, s. 46-51Subject(s): USA | Driver information | Speech | Prototype | | | Efficiency | Driver | | 914Bibl.nr: VTI P8167:1759Location: Abstract: The final prototype of a centralized voice information system, developed under the framework of the European CeMVocAS (Centralised Management of Vocal Interfaces Aiming at a Better Automotive Safety) project, was evaluated. This system manages all types of voice messages to the driver (i.e., input and output voice flows to and from car telephone, radio, and driver assistance systems) to minimize their disruptive impact on the basic task of driving. Analysis of the results included evaluation of (a) the part of the system responsible for determining the driver's potential availability to receive voice messages [driving situation recognition unit (DSRU)] and (b) the complete system (DSRU plus centralized voice interface management system). Results indicate that the system is quite robust in terms of vehicle, driver, and route variability; in addition, levels of system effectiveness, system efficiency, and user satisfaction were high.
