I am now working as a Research Scientist with the Amazon Alexa team in Cambridge, Massachusetts.

 

I was awarded my B.Tech. and Ph.D. degrees in Electrical Engineering from the Indian Institute of Technology (IIT) Kanpur, India.

My Ph.D. thesis was entitled "Analysis of Pitched Polyphonic Music for Source Transcription", reflecting my research interests in acoustic signal analysis and music information retrieval.

 

 

 

 

Whilst working in the Language and Brain lab, University of Oxford, I helped to develop the FlexSR automatic speech recognition (ASR) technologies using phonological considerations within the framework of the Featurally Underspecified Lexicon (FUL) model:

- A phonological feature based transfer learning scheme for creating ASR systems for under-resourced languages

- A phonological feature based computer-aided pronunciation training system that detects mispronunciations and supplies corrective feedbacks to the learners of a second language
