Abstract
VoiceXML applications are described by context free grammars. Then, recognized vocabulary is
limited. We show in this paper one possible approach in order to use VoiceXML applications and
speech web services, together. The idea is to use capabilities of speech-dictation systems when
the input value is not recognized in an active grammar. A prototype of VoiceXML application using
speech web services is presented. A user can speak a free sentence, in English for instance, and
receive a French translation, on the same modality (phone) or via another one (PC screen, for
example).
