The final part of the theoretical background addresses initial consonants in Vietnamese and Vietnamese English. The methodological section provides information about the informants, the recording, and data processing prior to the analysis itself. I also present graphs and tables illustrating the statistical calculations - using ANOVA and Tukey's post-hoc tests - that identify the relations among the measured units.
