Hey, I am Supriya Khadka!

Hello, I am Supriya!


I am a Computer Engineering Graduate, currently working as Conversational AI Engineer at Diyo AI. My work is an intersection of Natural Language Processing and Conversational Design. Currently, I am researching how to make large language models(LLMs) robust for low-resource languages like Nepali.

I love buying novels, reading novels and talking about novels in my free time. I also enjoy watching movies and series. If you want to talk about NLP, books or movies, hit me up!

Nepali Text-to-Speech System

Natural sounding Nepali Text-to-Speech system. Finetuned on our own data, available here.

Built using Tacotron-2 architecture (for spectrogram generation) and Hifi-GAN and WaveGlow (for vocoder), all of which implemented in PyTorch.

NepaliXlit

Adaptation of IndicXlit for Nepali systems. Prepared a parallel corpus of ~3500 romanized-nepali words, incorporating the nuances of Nepali conversational styles

Finetuned using fairseq with an incremental approach, finally obtaining Top@5 accuracy of 86% in the third iteration.
