About
I am currently working as a Senior AI Researcher at Kaliber.ai. I joined Kaliber Labs in August 2018 after completing my Masters. At Kaliber Labs, I work in the ML Researchers team who are involved in developing Computer Vision based AI Solutions for Endoscopic video feeds. Prior to that I was associated with the Speech Processing Group at the department of Electronics and Electrical Engineering, Indian Institute of Technology (IIT) Guwahati in the capacity of Assistant Project Engineer. I was mostly involved in developing Automatic Speech Recognition (ASR) systems in native Indian languages like Assamese, Mizo etc in Ministry of Electronics & Information Technology (MEITY), Govt. of India sponsored R&D projects. I was also involved in developing IVR systems as a front end for interacting with end users and speech data collection. During my stay at IIT Guwahati, I was fortunate to work under the supervision of Prof. Rohit Sinha , Prof. S R M Prasanna , Prof. Priyankoo Sarmah and Prof. Samudravijaya K . I shall always be grateful to them for their support and guidance in shaping my career as an AI Researcher.

Banriskhem K. Khonglah
Senior Research Scientist at Cerence
I have worked with Abhishek Dey during the early struggling period of our careers. He is a person who can dedicate and work extensively for hours until and unless the target is met. During his worst personnel time also, this guy has the strength and power to stay calm, focus and work on the target work to get it done, not just because he has to satisfy his boss or seniors, but because self satisfaction and contribution to his team gives him immense happiness, which one can see in his face. He loves working with this team and take them as family. Anyone who worked with him and who knows him, including myself will recommend him for any team or firm.
Senjam S D
Software Engineer
Abhishek was an extraordinary student. He was totally dedicated and passionate towards his works. He likes working in pressure and fulfill the tasks within the time limit and he is also a very good team player with great leadership skills. I wish him very best of luck for his future endeavors.
