Upton

ʌɪ

price /prʌɪs/

Strict IPA

aɪ̯

price /praɪ̯s/

Standard

price /praɪs/

In English, both in Received Pronunciation and in General American, the IPA phonetic symbol /aɪ/ corresponds to the vowel sound in words like "price", "fly" and "time". This diphthong is informally called long I and a bit more formally "the long sound of the letter I".

In strict IPA diphthongs need an inverted breve under their less prominent vowel: /aɪ̯/. However the notation we are using does not have the symbol /a/ by itself, and therefore we know that a vowel after /a/ has an implied inverted breve.

This vowel can be pronounced as [aɪ̯], [ʌɪ̯] or (in Australian English) [ɑe̯]. In Southern American English this phoneme can be the monophthong [aː].

At the advice of Clive Upton the Concise Oxford Dictionary altered the British tradition and now uses /ʌɪ/ instead of /aɪ/; later Oxford Dictionaries Online followed the same convention.[1] The phonetician Jack Windsor Lewis says "the verdict on /ʌɪ/ alongside /aʊ/ must be that it is a very regrettable departure from EPD14b [Daniel Jones English Pronouncing Dictionary] that would be better abandoned in future."[2]
