It’s on the download page, as usual.

The two significant changes in this version are:

1. Support for installs on Debian-based distros (e.g. Ubuntu)

2. Support for perl versions > 5.8 (e.g. Fedora 9)

I haven’t had time to do much testing, especially on Fedora, so please report any issues.

The script is available at http://www.voiceglue.org/vxml_tests/ex.vxml ; and feel free to point a voice browser at it and run it directly off our site if you like.

• One big focus over the last 5 months has been to clean up and fix various small issues in the 0. series of releases as well as supporting voiceglue users on the forum. We’re now at 0.6, which has been relatively stable. We try to answer all questions on the mailing list within a day or two.
• We’ve also been working on integrating and testing speech recognition functionality. We’ve been making use of Asterisk’s res_speech.so interface, which is the Digium-blessed approach to interfacing with speech engines. Right now we are only aware of support for Lumenvox under this interface which we are using as our test environment (and we should note that they have been helpful and supportive of our effort). As a future project goal we will probably build a Sphinx interface if no-one else is doing so. The res_speech interface was exposed to the AGI via a source-level patch in Asterisk 1.4, but this patch is now rolled into the 1.6 Beta; so we are now working with the 1.6 Beta. Our coding is complete for this effort, and we are in debug.
• We’ve been given a development key for Cepstral, and plan to integrate it as a commercial alternative to Flite.
• We’ve been keeping a list of feature requests, to plan into upcoming releases.

Our goal is to get speech recognition working at which point we will call it a 1.0 version. We will then take our feature request list, poll our user community to get your input, and schedule dot releases.

One last note, I (Steve) will be at Spring VON in San Jose if any voiceglue users would like to get together. Drop me a note.

Our panel was well attended, and we had a good discussion about what “sophisticated services” mean from both a carrier and an application perspective. Moderator Bryan Johns did a good job and made some thoughtful comments. Co-panelist Chris Gatch talked about the benefits of using a next gen carrier and how asterisk as a pbx can take full advantage of such services.

Our slides are attached here, short and sweet. We overviewed different areas of sophisticated services possible on asterisk, such as conferencing, outbound campaigns, ACD/CTI, etc., then we focused on IVR and gave a short 4-slide overview of VXML, openVXI, and Voiceglue (including the voiceglue architecture diagram below — you can click thru to flickr for a bigger version). Several people asked some insightful questions, and in the post-panel discussions we had some requests for future project directions such as call control.

On last item of note is that we had a good talk with Craig Campbell of Cepstral, who donated a SDK so that we can integrate his TTS into Asterisk — which we plan to do as soon as we finish with our ASR integration. We do have a bit a of a roadmap that we’ve been putting together, and we’ll get a post out on that in the near future.

It fixes a bug with the tag usage.

No simple update for this, best to uninstall the old and install the new.

I (Steve) will be on the panel along with a next gen service provider, and a very experienced Asterisk integrator. The title of the panel is Expanding to Sophisticated Services.

This is the inaugural year of the Asterisk World conference; which is the business-oriented counterpart to Astricon.

You can sign up for the full asterisk world conference, which gets you into all the keynotes and panels, or you can come to the expo only. As of today, you can still get a free expo pass if you go to the main VON site.

If you’re interested in Voiceglue, come talk to us at VON. Doug and I will be there all day Tuesday, and I’ll be back for Wednesday and part of Thursday as well.

This version fixes a bug with validation of identifiers in VXML files.

If you’re getting errors like these:

      Datatype error: Type:InvalidDatatypeValueException, Message:Value 'caller' does not match regular expression facet '([a-zA-Z]|[a-zA-Z$][a-zA-Z0-9_$]*[a-zA-Z0-9_])'

      Failed to parse the URI's content. Make sure that this document consists of valid VXML.

then you should definitely upgrade.

This version turns off Xerces XML validation, which reports valid
VXML documents (confirmed valid by XSV) as errors.

This version fixes a bug with cached grammars.

Thanks to those that are submitting bug reports, so they can get fixed!
