JVoiceXML vs Mobilus Visual IVR

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 or DTMF input. Dialog functions also include recording, telephony, and mixed-initiative conversations. The architecture allows custom extensions, and demo implementation platforms support Java APIs such as JSAPI and JTAPI. The repository includes modules for Mary, MRCPv2, JSAPI 2.0, JTAPI, and text implementations. The project names platform independence as a major goal. Its repository identifies the license as LGPL-2.1 and provides release downloads. The latest listed version is 0.7.8, which added an SRGS grammar processor with SISR support, Microsoft LUIS as a grammar processor, bug fixes, and a move to Gradle. JVoiceXML is listed for API, Linux, and self-hosted use.

Mobilus Visual IVR is a web service that routes customer inquiries to support destinations based on customer needs and call-center conditions. Destinations can include FAQs, web chat, LINE, chatbots, voicebots, and telephone support. A button or QR code can open the menu, which may also appear as a popup or small window without changing an existing page structure. Teams edit scenario flows in a graphical interface and use drag-and-drop controls to change IVR button destinations. Visual IVR offers simple and HTML/CSS design modes, with up to 50 registered templates. Each scenario flow can contain up to 100 contents, with smartphone and PC previews. Analytics cover access totals, referral sources, and user journeys, with reporting windows and ranking limits specified by the product page. A voicebot can send an SMS after a call with a link to the Visual IVR menu. Mobilus presents it for improving inquiry routing, self-service, and call-center load. Pricing is available by inquiry.
