Designed for attendees new to the speech technology area, this tutorial overviews the speech technologies, user interface design principles, and the markets for this fast-evolving industry. We highlight the key speech technologies, including automatic speech recognition (ASR), text to speech (TTS), voice biometrics, and dialogue management. Learn how these technologies are used to develop interactive voice response (IVR) systems; voice-enabled personal assistants; and voice-enabled mobile applications, assistive applications, and voice applications for use in the car, TV, and other devices/appliances. Learn about the process of developing speech applications, principles, and best practices and the integration of speech with GUI and other UI modalities. Understand the players in the speech technology ecosystem.
