Speech & Dialog Research Group

Research in speech recognition, language modeling, language understanding, spoken language systems and dialog systems


Our goal is to fundamentally advance the state-of-the-art in speech and dialog technology. To achieve this, we are working in all aspects of machine learning, neural network modeling, signal processing, and dialog modeling. Recently, to support our work, we have developed the Computational Network Toolkit (CNTK), which makes it easy to define complex neural network structures, and train them across multiple GPUs with unprecedented efficiency. You can find out more about this work by exploring the projects and individual home pages listed below.

In addition to advancing our basic scientific understanding of natural language processing, our work finds an outlet in Microsoft products such as Cortana, Xbox, and the Project Oxford web services suite. We have developed two of the key services. LUIS (Language Understanding Intelligent Service) makes it very easy for a developer to add language understanding to applications. From a small number of examples, LUIS is able to determine a user's intent when they talk or type. CRIS (Custom Recognition Intelligent Service) provides companies with the ability to deploy customized speech recognition. The developer uploads sample audio files and transcriptions, and the recognizer is customized to the specific circumstances. This can make recognition far better in unusual circumstances, such as recognition on a factory floor, or outdoors. At runtime, both LUIS and CRIS are accessed via web APIs.

The Speech & Dialog Group is managed by Geoffrey Zweig.



In the past, the speech technology group has worked on other projects, including:
