Work Experience
Professional Experience
- Senior Research Scientist I currently work on natural language processing for clinical documentation.
- Machine Learning Engineer I worked in the speech team of Yaar Inc. Some of the applications that I worked on are speaker verification, keyword spotting and text-to-speech synthesis.
- Part-time Consultant Worked with a Toronto based start-up to enhance the speech recognition component for an iOS application. The application used CMU sphinx library for implementing the ASR.
Research
- Research Assistant, Computational Linguistics group @ University of Toronto, Toronto, Canada. My research area is statistical parametric speech synthesis with a focus on linear dynamical and autoregressive models, which are a class of continuous state space models. The project involves developing these statistical models and comparing their performance with deep neural network based models. research paper
- Research Assistant, Network Research Laboratory @ University of Toronto, Toronto, Canada. Added components to Lotos, a simulation software tool, developed in Java for building overlay networks. The work included implementing CSMA-CA protocol for wireless nodes and adding option for generating multiple tracks for simulating wireless nodes installed on trains.
- Bachelor’s Thesis Project, EEE department @ IIT Guwahati, Guwahati, India. Using a simple rateless encoding scheme, several opportunistic multicast algorithms were proposed and their performance studied in test networks using simulations. [thesis pdf] [publication]
- Summer Research Internship, Vodafone Chair Mobile Comm. Systems @ Technische Universität Dresden, Dresden, Germany. The project involved development of methods for generation and detection of finite length reconstructible ASK sequences to be used in a communication system employing single bit quantization at the receiver in order to enhance performance of the ADC in multi-gigabit-per-second communications.
