(This post has nothing to do with speech technologies or IVR applications. It’s merely a discussion on an implementation detail I described at the Erlang Montreal meetup and it’s rather technical.) In my previous post about my talk at the Erlang Montreal meetup, slide 15 briefly outlines how session timeouts are implemented in NuGram Hosted Server. […]

The Nu Echo team is pleased to announce the availability of NuGram IDE 2.3.0. This new release features full support for UTF-16 and UTF-8 with byte-order mark (BOM) and fixes a number of problems with non-European languages. The free Basic Edition is available at the usual location.
Last week at the first Erlang Montreal meetup, I gave a talk on what we’ve learned at Nu Echo developing the NuGram Hosted Server in Erlang. I just put the slides from the presentation on SlideShare. Here they are: Erlang at Nu Echo from Nu Echo Inc. View more presentations from Nu Echo Inc..
Ever wondered how to instrument an existing application for use with the NuBot IVR Testing Platform? My colleague Pascal wrote a helper function in Groovy for easy instrumentation of applications built using the Tropo Scripting API. The trick is to define a closure encapsulating the playing of DTMF sequences (these sequences are required in order […]
At Nu Echo, we’ve been developing and refining our own VoiceXML application framework for years now. As part of our nth rewrite (and I’ll talk more about that rewrite and why we did it in another post), we decided to experiment with CouchDB. (For those new to CouchDB, it’s a schema-less document-oriented database. A so-called NoSQL […]
Lately, I have been involved in the development of a new reusable VoiceXML dialog module. The module is invoked via a <subdialog> call with a number of parameters, one of which having an impact on the order of the questions asked by the module. Writing automated test scripts for such parameterized applications or modules […]
Loquendo and Nu Echo are proud to announce today the launch of a new partnership to provide a complete offering for the North American market, from speech technologies to professional services. This new partnership enables the companies to offer North American customers speech application development, dialog design, porting and tuning services to complement Loquendo’s existing […]
In my post on NuGram and CouchDB, I neglected to mention how the dynamic grammar was authored and, most importantly, tested. Having a repeatable process for testing grammars is very important when developing a speech application, as most grammars change and get more complex over time. Of course, the grammar was authored with NuGram IDE. […]
Just after hitting the “Publish” button last week for my previous post on NuGram and CouchDB, I realized the code I wrote had a serious flaw. Remember it? Here’s an excerpt: There are basically two problems with this code: On line 3, the application creates a new session on NuGram Hosted Server and the unique […]
Mark Headd, a new member of the Voxeo family, published a blog post last week on how to build speech recognition applications with Tropo. Since his post covered things like SRGS grammars and dynamic grammars, I couldn’t resist. I had to enter the fray and show how the dynamic SRGS grammar could be built using […]
