JVoiceXML
What it is
JVoiceXML is a free, open-source VoiceXML interpreter for Java, and the project describes its implementation as VoiceXML 2.1. It supports audio dialogs using synthesized speech, digitized audio, spoken input, and DTMF input. Dialog capabilities also include recording, telephony, and mixed-initiative conversations. Its open architecture allows custom extensions, while demo implementation platforms support Java APIs such as JSAPI and JTAPI.
The repository contains modules for 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 JVoiceXML 0.7.8, which added a more compliant SRGS grammar processor with SISR support, Microsoft LUIS as a grammar processor, bug fixes, and a migration to Gradle. JVoiceXML is listed for API, Linux, and self-hosted use, and is available at no cost.
