Your Next Computer May Know How You Feel
Friends, loved ones and pets can sense your mood almost instantly – and one day your computer may be able to do so pretty quickly as well.

UT Dallas computer scientist Yang Liu has received a three-year, $350,000 grant from the highly competitive Air Force Office of Scientific Research's Young Investigator Research Program to explore emotion recognition and modeling in speech processing.
Can't Make it to a Meeting? Send a Computer Instead
If you’ve ever wished you had an assistant to attend meetings with you, take notes and produce a concise summary, then you’ll be pleased to know that UT Dallas computer scientist Yang Liu hopes to one-up you: She’s working on software that would automatically do the job of that assistant.

She recently received a prestigious career-development award from the National Science Foundation that will fund a five-year, $400,000 project designed to find a more intelligent way to address issues related to speech summarization of meetings.
