Sound system Vowels MOUTH

For the current speaker, the diphthong in MOUTH appears to be [ɔʊ​]. Turner, however, cites the diphthong as [ɒʊ] , again with the nucleus advanced and raised to [ɐ] in pre-voiceless environments (1971: 125–126; 2002: 21). One might also note in the reading passage on the accompanying CD, that the speaker monophthongizes the vowel in around, transcribed as [əɹɔn] . So it appears that the production of this diphthong is variable.
