Readings

There are some extra readings on signal processing in this module, if you’d like to revisit that material from another author’s perspective. There is actually a large amount of further signal processing material in Taylor’s book, which is worth exploring.

Reading

Jurafsky & Martin – Section 8.4 – Diphone Waveform Synthesis

A simple way to generate a waveform is by concatenating speech units from a pre-recorded database. The database contains one recording of each required speech unit.

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.

Taylor – Section 12.7 – Pitch and epoch detection

Only an outline of the main approaches, with little technical detail. Useful as a summary of why these tasks are harder than you might think.

Ladefoged (Elements) – Chapter 10 – Fourier analysis

An attempt to explain Fourier analysis. Although chapters 1-9 are great, I actually do not recommend chapter 10.

Ladefoged (Elements) – Chapter 11 – Digital filters and LPC analysis

A brave attempt to use 'long hand' to spell out how LPC analysis works, but not a recommended reading.
