[latexpage] Overview It's actually not a well-defined problem, as there are just so many different ways to define one's voice. So, it's not clear to develop a traditional codec in…

TL;DR: Modern neural audio codecs often reconstruct missing high-frequency content by guessing it with a generative decoder. HE-NAC instead combines this bitrate-free prediction with a small amount of explicitly coded residual information for…

Neural Speech and Audio Coding: A Research Thread Over the past several years, my group has been exploring a common question from multiple angles: how should we design neural speech…

[latexpage] Have you ever wondered about a speech codec that's dedicated to your speech trait? Why? Of course, it is to reduce the bitrate while maintaining the speech quality after…
