Shahab Jalalvand - PhD

Senior research scientist

Interactions Corp.

New Providence, NJ

Bio:

Shahab is a senior researcher in automatic speech recognition (ASR) and natural language processing (NLP) at Interactions Corp, US, where he joined in 2017. Prior to joining Interactions, he was a researcher and developer at PerVoice Inc, Italy in 2016. Prior to PerVoice, he was a PhD student researcher at FBK, Italy in 2012-2015. He holds a PhD degree in computer science from ICT Doctoral school at the University of Trento, Italy (2017). He obtained his MSc degree in artificial intelligence from Iran University of Science and Technology, Iran (2012) and BSc degree in computer engineering from the same university (2009).

His research has been focused on ASR, NLP and spoken language understanding (SLU) systems and the applications of machine learning algorithms to improve these systems. He has published over 15 journal and conference papers on these topics. He has been an active member of ISCA group from 2012.

Shahab has developed several techniques to automatically predict the quality of ASR transcriptions when no human reference is available, "TranscRater". He has developed techniques to rapidly adapt the ASR and SLU systems and improve their robustness towards speaker/accent variation and domain variation.

Currently, Shahab is conducting his research on spoken language understanding for customer service in different domains, specially when limited in-domain data is available. Moreover, he is developing techniques to improve the language models in the SLU systems for customer service applications.
