A Solutions Architect at LumenVox, a leading provider of speech recognition and text-to-speech software, Stephen specializes in the design and development of complex voice user interfaces (VUIs) as part of their client services team, working to improve the user experience for anyone interfacing with speech technologies.

He has worked on dozens of speech applications, ranging from simple yes/no-style interactions to complex, multi-slot natural language interfaces. His role at LumenVox encompasses a variety of functions, including pure design/consultation work and also development and training.

Speech-recognition apps require specialized testing methods that can be applied to other interfaces as well.
