Academic interests and background

Here, my research work is to examine the acoustic properties of Norwegian Infant Directed Speech (IDS) and its role in speech sound discrimination, word comprehension, and word production in 6 to 18-month-old Norwegian-learning infants. In addition, infants' language skills will be tested, in an eye-tracking paradigm, at the ages of 6, 9, 12, and 18 months.

Before that, I worked as a Senior Project Scientist in the Acoustic Lab at the Indian Institute of Technology (IIT), Kanpur (INDIA). In addition, I have finished my PhD from the Acoustic lab at IIT Kanpur, India, where research work was based on speech acoustics and multi-microphone signal processing. My PhD thesis topic was "Source localization strategies for audible frequencies". I have completed my university and master's degree in Electronics and Communication Engineering

I have understanding of frequentist and Bayesian statistics for data analysis. Further, I also have experience working on tools like Praat and Audacity. 

I have hands-on experience with machine and deep learning models (Regression, Classification, Fully connected, CNN, LSTM, and GRU). I am also familiar with linear algebra, optimization, and estimation techniques. I have also worked on deep learning toolkits like TensorFlow.

In summary I am not a linguist but a speech engineer and my academic intrests are:

  • Speech Acoustics
  • Early Language Developent
  • Automatic speech recognition
  • Audio/Speech Signal Processing
  • Frequentist and Bayesian statistics
  • Machine/Deep Learning
  • Bilingualism/multilingualism

Work Experience (after PhD: 13 Months)

2022- till date – Postdoc – MultiLing – University of Oslo, Norway.

2020-2022 – Senior Research Scientist - Indian Institute of Technology (IIT), Kanpur, India
