The VoiceXML Forum's Certification Program certifies that implementation platforms conform to the W3C VoiceXML 2.0 specification. The goals include:

• interoperability of platforms, voice service providers, tools, and applications
• reduce customer confusion over language support and compatibility
• a common test suite available to the entire industry
• certified 3rd-party independent testing:

Platform vendors can test their platforms against the publicly available test suite. VoiceXML Forum members have access to a test harness to assist in local execution of the tests. Alternatively, members can also run the tests directly from the Forum�s website without having to install any software. When a vendor is ready to submit their platform for testing, they should contact the Forum at [email protected].

CT Labs, an independent testing laboratory, will run the conformance tests on behalf of VoiceXML Forum.
