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’).
Johnson (Phonetics) – Chapter 2 – The Acoustic Theory of Speech Production: Deriving Schwa
Derives the acoustic features of the vocal tract in terms of the source-filter model
Johnson (Phonetics) – Chapter 6.1 – Tube models of vowel production
Deriving the resonances and formant structures of vowels using 2 and 3 tube models of the vocal tract.
Schaedler – Seeing Circles, Sines and Signals
A very nice concise primer on the basic components of digital signal processing with great visual demonstrations.
Taylor – Section 10.1 – Analogue signals
It’s easier to start by understanding physical signals – which are analogue – before we then approximate them digitally.
Taylor – Section 10.2 – Digital signals
Going digital involves approximations in the way an original analogue signal is represented.
Wayland (Phonetics) – Chapter 6 – Basic Acoustics
A concise introduction to acoustics: sounds, resonance, and the source-filter theory
Wayland (Phonetics) – Chapter 7 – Digital Signal Processing
An intuitive introduction to acoustics digital signal processing
