Signal Processing
SCOOT: Sound and Signal Processing
Sound
- · Lecture 2 in Roger Moore’s course on Speech Processing is an introduction to the physics of sound [Slides Audio].
- In Edinburgh's SpeechZone, speech signals are covered here.
- This Introduction to Speech Acoustics from Listen Lab is a series of Youtube videos covering some aspects of acoustics, signal processing and phonetics.
Signal Processing
Speech Signal processing transforms speech acoustics to features which represent speech information (for instance the distribution of energy over time and frequency), and vice versa.
- · Lectures 11-20 in Roger Moore’s course on Speech Processing cover speech signal processing. They are written for Computer Science students and assume some mathematical knowledge. They make use of the visual programming language Pure Data.
