Speech Application Development & Tuning

Your speech application isn't delivering the caller experience or the task completion rate that you expect?

We can improve it. Significantly.

Many speech applications provide a worse user experience and task completion rate than they should, simply because they haven't been properly designed or tuned. Now would be a good time to get the return on investment you initially planned for.

Can’t say enough how awesome Nu Echo has been in this effort.

The most powerful integrated tuning workbench available.

Atelier is Nu Echo's proprietary speech application tuning environment, used by our speech scientists to enhance the performance of our customers' applications. It provides a complete suite of data analysis and diagnostic features that enable us to quickly and efficiently target problem areas, and to find and test solutions in a reliable iterative process. With complete multi-engine support in a single environment, Atelier can tune any application.

Tuning a speech application requires the ability to perform off-line speech recognition experiments iteratively, with the grammars – static or dynamic – used by the application, and to analyze the results in order to improve speech recognition accuracy, set confidence thresholds, test post-processing algorithms, etc.
