Hi Suman, IMO it is no problem that those libs do have an incompatible license. This GSoC project is about Speech2Text and not about transcoding some audio files. Having an EnhancementEngine that transcodes audio files (and Audio Tracks of Video Files) to a format that can be processed by Sphinx is nice to have but not a requirement.
You can still implement two engines 1. Audio Transcoding Engine 2. Speech2Text Engine (1) would stay in your repository. Make a release and publish on maven central (2) would be contributed to Apache Stanbol and provides Text2Speech functionality. LGPL is fine for nearly every commercial use case. So users need just to add the Bundles required for the use of (1) to to their launcher to use the functionality of (2) with any audio/video format. The only thing we can not do is to provide an launcher that already includes (1) in Stanbol. best Rupert On Thu, May 15, 2014 at 11:13 AM, Suman Saurabh <ss.sumansaurab...@gmail.com> wrote: > Hi Rupert, > > On Wed, May 14, 2014 at 5:11 PM, Rupert Westenthaler < > rupert.westentha...@gmail.com> wrote: > >> Please Note that Xuggler is LGPL.
