NuGram (www.grammarserver.com) is a hosted platform used to host and share speech recognition grammars (both static and dynamic, i.e. grammar templates) for use by hosted IVR platforms (Tropo, Voxeo Prophecy, etc.) It's totally free, although it's not really meant for production use as of now. If you need it in production, please contact me at dominique DOT boucher AT nuecho DOT com.
From it's companion site, nugram.nuecho.com, you can also download a complete Eclipse-based grammar development environment (NuGram IDE) from which you can upload your grammars to NuGram Server.
Regarding the opacity of the site, maybe we could work on that... We are very open to constructive comments!
We don't provide a complete self-service setup process yet We are working on that. Just apply for the free trial and we'll help you bootstrap the whole thing.
