What new engineering hurdles did the evolution toward Spoken Dialogue Systems (SDS) introduce?
Answer
Integrating robust speech recognition with NLU challenges
The development of Spoken Dialogue Systems (SDS) during the 1970s and 1980s introduced significant technical challenges that text-based systems inherently avoided. The primary hurdle was successfully integrating robust speech recognition—the accurate conversion of spoken audio into transcribed text—with the established complexities of natural language understanding and dialogue management. Furthermore, interaction dynamics shifted, necessitating research into how systems could provide appropriate assistance and information tailored specifically for auditory interfaces, such as developing context-sensitive help appropriate for a non-visual environment.
