NLU Engine Overview

The Vestec NLU (natural language understanding) Engine is designed to significantly reduce the cost of building and maintaining natural-speech call-routing applications in Enterprise contact centers as well as significantly increasing their routing accuracy and call-completion rates. Our NLU engine integrates with third-party speech recognition engines – such as those of Nuance – and supports all major spoken languages.

Vestec NLU engine significantly boosts the ROI of Enterprise natural speech call-routing applications. It provides the following specific benefits compared to conventional call-routing speech application development approaches: (a) smaller training data set requirement; (b) full grammar transparency and manipulability; (c) rapid automated grammar tuning; (d) robust processing of out-of-grammar utterances; (e) better handling of accented speakers; and (f) sophisticated contextual interpretation of utterances.

Our NLU engine is priced at a fraction of the cost of conventional natural-speech, large-vocabulary speech recognition engines. It can be integrated with all Enterprise Nuance speech recognition engines – ASR, OSR, and v9 – and supports all major spoken languages. Vestec is currently working with leading Enterprise contact center platform vendors for marketing and deployment of its NLU engine.
