Exercise 2.6.1: Word Boundaries
Here is the audio for the Exercise 2.6.1. Download the wave file (ilang.wav) and open it with a sound editing program such as Praat which is free to download. (Another sound editing program is Audacity, also free.)
The video below shows how it sounds and looks like when you open the file with Praat. The top part is the waveform and the bottom part is the spectrogram of the audio. You only need the waveform to do the exercise, it will be easier to work with.
