The SpeechDat project aims to produce speech databases for all official languages of the European Union and some major dialectal variants and minority languages resulting in 28 speech databases. They will be recorded over fixed and mobile telephone networks. This will provide a realistic basis for training and assessment of both isolated and continuous-speech utterances, em ploying whole-word or subword approaches, and thus can be used for developing voice driven teleservices in cluding speaker verification. The specification of the databases has been developed jointly, and is essentially the same for each language to facilitate dissemination and use. There will be a controlled variation among the speakers concerning sex, age, dialect, environment of call etc. The validation of all databases will be carried out centrally. The SpeechDat databases will be trans ferred to ELRA for distribution. Next databases to be recorded will cover East European languages.

In this research w e h a v e studied several human factors problems that are connected to the deployment o f speaker veri cation technology in telecommunication services. We i n v estigate the perception of the safety o f a calling card service when it is protected by speaker veri cation on the 14 digit card number, and compare it to the perceived safety of speaker veri cation and PIN. Moreover, we compare a voice based interface to the service with a DTMF based interface. The results are crucial for guiding the introduction and deployment of speaker veri cation technology in actual applications.
