Figure 1.1 on p. 3 of Rethinking Reduction (Introduction) was incorrectly transcribed and cited in the original publication of the book.

The example comes from a recording made by Natasha Warner, and should be referenced with the following citation:

Ernestus, M., & Warner, N. (2011). An introduction to reduced pronunciation variants [Editorial]. Journal of Phonetics, 39(SI), 253-260. Full text

The corrected figure is as follows:

Figure 1.1: yesterday, realized as ['jεʃeɪ], from a recording made by Natasha Warner (Ernestus & Warner, 2011)

This realization of 'yesterday' is taken from the utterance "We were supposed to see it yesterday, but I felt really bad."
