Hemant A. Patil received Ph.D. degree from the Indian Institute of Technology (IIT), Kharagpur, India, in July 2006. Since 2007, he has been a faculty member at DA-IICT Gandhinagar, India and developed Speech Research Lab at DA-IICT, which is recognized as ISCA speech labs. Dr. Patil is member of IEEE, IEEE Signal Processing Society, IEEE Circuits and Systems Society, International Speech Communication Association (ISCA), EURASIP and an affiliate member of IEEE SLTC. He is regular reviewer for ICASSP and INTERSPEECH, Speech Communication, Elsevier, Computer Speech and Language, Elsevier and Int. J. Speech Tech, Springer, Circuits, Systems and Signal Processing, Springer. He has published around 226 research publications in national and international conferences/journals/book chapters. He visited department of ECE, University of Minnesota, Minneapolis, USA (May-July, 2009) as short term scholar. He has been associated (as PI) with three MeitY sponsored projects in ASR, TTS and QbE-STD. He was co-PI for DST sponsored project on India-Digital Heritage (IDH)-Hampi. His research interests include speech and speaker recognition, TTS, infant cry analysis. He has received DST Fast Track Award for Young Scientists for infant cry analysis. He has coedited a book on Forensic Speaker Recognition with Dr. Amy Neustein (EIC, IJST Springer). Presently, he is coediting two books in speech technology for medical-domain. Dr. Patil has taken a lead role in organizing several ISCA supported events, such as summer/winter schools/CEP workshops (such as speaker and language recognition, speech source modeling, text-to-speech synthesis, speech production-perception link, advances in speech processing) and progress review meetings for two MeitY consortia project all at DA-IICT Gandhingagar. Dr. Patil has supervised 04 doctoral (including doctoral thesis supervision in spoofing attacks) and 42 M.Tech. theses. Presently, he is supervising 03 doctoral students. Recently, he offered a joint tutorial with Prof. Haizhou Li during Asia Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC) 2017 and also during INTERSPEECH 2018. He will be offfering joint tutorial with Prof. H. Kawahar during APSIPA ASC 2018, Honolulu, USA, Nov. 12-15, 2018. He has been selected as APSIPA Distinguished Lecturer (DL) for 2018-2019. He has delivered 11 APSIPA DLs in three countries, India, China and Canada.
