Bilingual Chinese/English voice browsing based on a VoiceXML platform

We report on the development of English-Chinese bilingual speech applications on a VXML platform. VXML supports displayless voice browsing of Web content. We have developed the CU voice browser based on OpenVXI 2.0. We have also integrated the voice browser with the OpenSpeech Recognizer (for English speech recognition), CU RSBB (for Chinese speech recognition), Speechify (for English speech synthesis) and CU VOCAL (for Chinese speech synthesis) in order to support bilingual voice browsing. The CU voice browser includes an attribute for identifying the appropriate language for speech input/output, thereby invoking the appropriate speech engine for recognition/synthesis. We have developed two bilingual sample applications $CU weather and CU news. This paper provides the associated VXML documents that specify these bilingual dialogs for browsing weather and news information respectively.
