This book, said to be written for native speakers of English as well as second and foreign language learners, is about the differences between the pronunciation of words in careful and casual speech, despite identity of spelling. It presents as models written-language texts and their phonetically written equivalents in the prestige British Received Pronunciation (RP) variety, and then provides more texts as exercise to be transcribed both ways. Almost all of the exercises are anonymously authored texts of 40 or more lines, on a variety of topics. Answers are given in an appendix. The idea is that learning to write English phonetically will improve nonnative speakers' pronunciation and, one supposes, promote the more accepting attitude of native speakers toward casual speech reductions.
