Quality and Usability

Sai Sirisha Rallabandi



I am Sai Sirisha Rallabandi, a Ph.D. student working with Professor Sebastian Möller at Technische Universität Berlin. Prior to this I did my Masters by Research at International Institute of Information Technology Hyderabad (IIITH), India. My research interests are: Text-to-Speech Synthesis, Voice Conversion and Cross-Lingual tasks. During my Ph.D. I will be working on "Social perceptions of Synthetic speakers". Here, I will mainly focus on understanding the speech features contributing to personality of a person. Furthermore, I will be modeling the speech features or the synthesis procedure itself for rendering more appealing and confident synthetic voices.
