Introduction
Research
Center for Speech Technology

Dr. P. Vijayalakshmi, a distinguished academic and researcher, is a Professor and Head of the Department of Electronics and Communication Engineering. She has 28 years of experience in teaching and research, with four years dedicated exclusively to speech signal processing.

She is a Senior Member of IEEE (since 2016) and a member of the IEEE Signal Processing Society. Additionally, she is a Fellow of the Institution of Electronics and Telecommunication Engineers (IETE), reflecting her extensive contributions to the field.

Dr. Vijayalakshmi earned her Bachelor of Engineering (B.E.) degree in Electronics and Communication Engineering with First Class and Distinction from Bharathidasan University.

She has published over 120 research publications in refereed international journals and in proceedings of international conferences. As a principal investigator she is currently involved in MeiTy funded project titled “Speech Assistive Technologies” – NLTM- BHASHINI.and a DST IMPRINT IIC project on “Development of Speech-to-speech translation systems for Hindi, Tamil and English” and “Development of bidirectional Hand-gesture recognition system” funded by DST-TIDE. As co-PI she is currently involved in MeiTy, TVA, DST-CRG funded projects. Further she has completed several other projects as PI and Co-PI that are funded by MeiTy, New Delhi, AICTE, DST-TIDE, and Tamil Virtual Academy, a Government of Tamil Nadu organization, and two projects funded by SSN Trust as well. She is a recognized supervisor of Anna University and currently guiding Five fulltime Ph.D scholars in the field of Speech Technology.

Her areas of research include Speech Signal Processing, Speech Enabled Assistive technology, Speech synthesis, and Speech recognition.

She was instrumental in establishing the “Speech and language technologies lab” to carry out research in the field of speech technology. (website link – speech.ssn.edu.in)
