JVoiceXML is a free, open-source VoiceXML interpreter for Java, described by its project as implementing VoiceXML 2.1. It supports dialogs that combine synthesized speech or digitized audio with spoken input and DTMF recognition. Dialog capabilities also include recording, telephony, and mixed-initiative conversations. An open architecture allows custom extensions, and demo implementation platforms support Java APIs such as JSAPI and JTAPI. Repository modules include Mary, MRCPv2, JSAPI 2.0, JTAPI, and text implementations. The project identifies platform independence as a major goal. Its GitHub repository lists an LGPL-2.1 license and downloadable releases. The latest listed release is version 0.7.8; it added an SRGS grammar processor with SISR support, Microsoft LUIS as a grammar processor, bug fixes, and migration to Gradle. JVoiceXML is listed for API, Linux, and self-hosted use.
