During the six months of conducting this project, I mainly achieved two goals: 1) Developed a prototype system to allow users to generate and customize the agent through simple text editing. The system takes a text file containing the transcript of the template speech and the user's feedback mode, then creates the tutoring agent accordingly for adaptive and personalized tutoring. It is part of a paper published in EICS 2021 now.2) Developed a novel way to allow users to awake the device by changing the prosody when speaking the keyword (e.g., Alexa) for accurate device activations. Evaluation studies show significant advantages of this method compared to Keyword Spotting based method. The results are summarized into a top-conference paper which is under review.
