You can create a multiple language voice-enabled application using the default VoiceXML gateway and recorded prompts, as well as developing an application that uses several VoiceXML gateways for each language. The Voice Kit provides the means to add another language, or several languages, to an existing application, or to create a multiple language application model from scratch.
This feature includes:
● Multilingual alternative texts in Speak items
● Multiple input phrases for list-of-choices grammars
● Languages and componentization
