Speech Synthesis Module 6: Spectral Envelope

[Shijie Yao]

In the Speech Signal Modelling video of Module 6, there is a spectrum (fig 1) which could be decomposed as an addition of spectra of periodic and aperiodic components. I didn’t quite get what Simon was explaining at 10:35 (fig 2) about the lower spectrum and the video (videos in the whole module) seems to be caption-less and transcription-less…?

Thank you.

(This question doesn’t really belong to any existing topics under Speech Synthesis so I posted in General questions…)

The Speech Signal Modelling video now has subtitles and a transcript.

Let me know if this helps, and post follow-up questions here.
