He joined Carnegie Mellon University in 1989 and worked with Raj Reddy and Kai-Fu Lee on speech recognition. At CMU, Huang directed Sphinx-II speech system research and achieved the best performance in every category of DARPA's 1992 benchmarking. He received the Allen Newell research excellence medal for his leadership in speech recognition in 1992, and IEEE Speech Processing Best Paper Award in 1993. He was elected to be a Fellow of IEEE in 2000, and a Fellow of ACM in 2017. Huang has co-authored over 100 papers and two books: Hidden Markov Models for Speech Recognition, and Spoken Language Processing, Prentice Hall]. In 2014 he coauthored a historical speech recognition review with Raj Reddy and James K. Baker for Communications of the ACM that reflected several generations of speech research. In 2016, he led his team reaching a historical human parity milestone in transcribing conversational speech on the Switchboard task. In 2018, he led his teams achieving more historical human parity milestones in Chinese to English Machine Translation on the WMT-2017 task. He was promoted to CTO to lead Azure AI Cognitive Services in 2020. He is best known for founding and leading Microsoft's speech and language initiatives as well as his pioneering work on Microsoft's multimodal interactive MiPad prototype as Bill Gates demonstrated at the Consumer Electronics Show in 2001.
