Prestudy and prototyping related to road safety aspects of novel speech & language interfaces in connected vehicles

Purpose and goal

The purpose was to investigate and demonstrate the possibilities with speech interfaces in heavy vehicles, and to form a consortium and formulate a collaborative project. A literature study including design recommendations was produced, and a prototype was developed, which have been used in workshops with Trafikverket, VTI och Scania. Veridict and Scania has as a result formed a common project proposal to FFI focused on development of demos and tests applying Veridict´s technology in connected vehicles.

Results and expected effects

A literature study gave a deep analysis and identification of required areas of technical development. The study also comprised design recommendations for speech interfaces, and hypotheses regarding system properties obtainable in three development stages. This should be tested in a follow-up project. A mobile, speech controlled prototype was developed containing relevant in-traffic example services. The prototype was used for dissemination and workshops s and has led to the formulation of a follow-up collaboration project for technical demonstrators and tests in vehicles.

Approach and implementation

The pre-study involved 3 WPs (AP1-AP3), one for each purpose with dedicated activity leaders. AP3 with dissemination, forming of a consortium and establishment of a collaboration was initiated early and resulted in several proposals, of which one technical collaboration between Scania and Veridict was realized into a submitted project proposal. The report in AP1 was used as a basis for the technical development in AP2. The development was performed iteratively using agile methods, which enabled the prototype to be used in various stages for dissemination and workshops in AP3.
