Applied Scientist Intern
Jun 2023 – Nov 2023 Cambridge, UK
Work as an applied scientist intern to develop large-scale TTS system based on large language models (LLM).
 
 
 
 
 
Xiaohongshu
Research Intern
Aug 2020 – May 2022 Beijing, China
Work as a researcher intern to investigate the application of speech representations in TTS.
 
 
 
 
 
Sogou
Researcher
Dec 2020 – Jul 2021 Beijing, China
Work as a researcher on singing voice conversion. We aim to develop a commercial singing conversion system which can convert arbitrary singing voice to the target timbre. High sound quality and accurate melody expression are both required.
 
 
 
 
 
Tencent AI Lab
Research Intern
May 2020 – Dec 2020 Beijing, China
Research topic is multi-singer singing voice conversion. We propose a MelGAN based end-to-end PPG-SVC model. It significantly improves the sound quality and singer similarity over the conventional PPG-SVC framework. The work is summarized to the paper, Phonetic Posteriorgrams based Many-to-Many Singing Voice Conversion via Adversarial Training.
 
 
 
 
 
Microsoft Research Asia & Microsoft STCA
Research Intern
May 2018 – Sep 2019 Beijing, China
Supervised by Frank K. Soong and Lei He. We aim to improve the robustness and naturalness of end-to-end TTS. Two main works are published to INTERSPEECH 2019, A New GAN-based End-to-End TTS Training Algorithm and Exploiting Syntactic Features in a Parsed Tree to Improve End-to-End TTS. We also investigate the conversational TTS using the end-to-end approach. The work is published to SLT 2021, Conversational End-to-End TTS for Voice Agents.
