We’re presenting the material in a different order to the Wayland textbook. We’re focusing on digital signals this week, but you might also want to look at Chapter 6 “Basic Acoustics” this week (it’s also the module 4 essential reading, so if you read it this week you’ll be ahead for that. If you don’t get to it until next week, don’t worry!).
The background reading on digital signals is fairly high level. If you want to see more maths, you can look at the extension materials in the labs or the references mentioned there.
Reading
Wayland (Phonetics) – Chapter 7 – Digital Signal Processing
An intuitive introduction to acoustics digital signal processing
Wayland (Phonetics) – Chapter 6 – Basic Acoustics
A concise introduction to acoustics: sounds, resonance, and the source-filter theory
Schaedler – Seeing Circles, Sines and Signals
A very nice concise primer on the basic components of digital signal processing with great visual demonstrations.
Handbook of phonetic sciences – Ch 20 – Intro to Signal Processing for Speech (Sections 1-5)
Written for a non-technical audience, this gently introduces some key concepts in speech signal processing. Read sections 1-5 (up to and including 'Fourier Analysis').
