This tutorial is about the evolution of speech technology from research to a mature industry. Today, spoken language communication with computers is becoming part of everyday life. Thousands of interactive applications using spoken language technology— known also as “conversational machines”—are only phone calls away, allowing millions of users each day to access information, perform transactions, and get help. Speech recognition, language understanding, text-to-speech synthesis, machine learning, and dialog management enabled this revolution after more than 50 years of research. . | Speech Technology from Research to the Industry of Human-Machine Communication Roberto Pieraccini SpeechCycle 26 Broadway 11th Floor New York NY 10004 roberto@ 1 Introduction This tutorial is about the evolution of speech technology from research to a mature industry. Today spoken language communication with computers is becoming part of everyday life. Thousands of interactive applications using spoken language technology known also as conversational machines are only phone calls away allowing millions of users each day to access information perform transactions and get help. Speech recognition language understanding text-to-speech synthesis machine learning and dialog management enabled this revolution after more than 50 years of research. The industry of speech continues to mature with its evolving standards platforms architectures and business models within different sectors of the market. 2 Content Overview In this tutorial I will briefly trace the history of speech technology with a special focus on speech recognition and spoken language understanding from the early attempts to today s commercial deployments. I will summarily describe the most successful ideas and algorithms that brought to today s technology. I will discuss the struggle for ever increasing performance the importance of data for training and evaluation and the role played by government funded projects in creating effective evaluation benchmarks. I will then describe the birth of the speech industry in the mid 1990s with the role played by the Voice User Interface and dialog engineering disciplines in bringing speech recognition from a laboratory accuracy challenge to an enabler of usable interfaces. I will describe the rising of standards such as VoiceXML SRGS SSML etc. and their importance in the growth of the market. I will proceed with an overview of the current architectures and processes utilized for creating commercial spoken dialog systems and will provide several case .
