JVoiceXML vs Voicent

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.

Voicent develops software for automated voice, email, and text communication, with point-and-click controls for sharing information and exchanging ideas. Its hosted service runs in a browser and can be accessed from computers, phones, and tablets. Cloud plans include call-center features such as agent dashboards, predictive dialing, and campaigns. Cloud calling covers the USA and Canada; on-premise software supports worldwide use with local phone and text services and requires Windows. Voicent says its cloud service has no contact limit and allows unlimited contact imports without extra fees. Calls are billed from pickup to hang-up, with a 30-second minimum followed by six-second increments. Features include call recording, voicemail drop, and dialing modes such as predictive, progressive, preview, click-to-call, and alternate phone dialing. CRM integrations include Salesforce, SugarCRM, Zoho CRM, MySQL, and Voicent CRM. The service lists a free plan, paid options from $19/mo, and a 30-day trial. Standard support is available weekdays from 8am to 5pm PST, excluding holidays or closures.
