On Thursday, November 2nd 2006 will be held the Drupal Meetup in Washington, DC. The plan include a presentation on Drupal and VoiceXML podcasting solutions in action by Mike from Trellon, and over the Washington, DC Drupalers group you can find a post titled Podcasting with some issues regarding podcasting with VoiceXML, like recording wav files which are not ready to use for podcasting and require a conversion.

VoiceXML services generally give you back WAV files at the conclusion of a call. To get a podcast running, you usually need to provide audio in an mp3 format. To get this to happen, expect to do some audio conversion. Lame is a safe bet for converting wav files to mp3, but also look at the ffmpeg wrapper for conversion as it handles errors a lot better and actually uses less memory than other services.

The second issue will be certainly the cost of such solution, especially if you want to use a paid service to run your VoiceXML software. Otherwise open source solution are available but it won’t be easy to install asterix, configure it, create mp3 and run everything on a webserver. Add always the cost of phone call ! I’ve been working with VoiceXML since many years and such implementation isn’t difficult to do, but most important will be certainly to make it easy to adopt.
