weak ɪ

Giuseppe Macario wrote
Although /'pɜ:fɪkt/ and /'ba:skɪt/ is what I have found in my British
dictionaries, I get the impression that the vowel pronounced by most
native speakers of English, no matter where they live, is not the /ɪ/.
The first vowel in /ɪk'spres/ confuses me, too. Are my doubts
justified?

I think the point here is that English has two separate vowel systems, the strong system and the weak system. The weak vowels are much less tightly defined than the stressed ones. Although people equate the weak vowel of 'perfect' and 'basket' with /ɪ/, it may vary towards [ə] more than a stressed /ɪ/ would.

The Longman Dictionary of Contemporary English uses a special double-decker symbol to represent a weak vowel that may be [ɪ] or [ə] or something intermediate between them (see picture).
The word perfect is a special case, because in this word some speakers do not weaken the unstressed vowel, but keep it as /e/ (as in the corresponding verb, /pəˈfekt/, where the vowel in question is stressed and therefore strong).
Nevertheless, my advice to Giuseppe is that he can safely treat the unstressed vowels in perfect (noun), basket, and similar words as being just like /ɪ/ (as in KIT). That’s how I believe I pronounce that vowel myself, and that’s what I hear millions of other people say.
A note of warning: Italian learners often have trouble perceiving and making the difference between English /iː/ (FLEECE) and /ɪ/ (KIT). The unstressed vowel we are discussing is certainly not like English /iː/.

  1. Speaking from an American perspective, I agree entirely with Professor Wells. I would add only that you would be unlikely to encounter [ˈpɜ˞fɛkt] in the US, at least in my experience. [ˈpɜ˞fɪkt] would be the norm.

  2. Dear friends, what should I do in order to see your phonetic symbols in my computer? Thanks.

  4. I'd identify the unstressed vowels in both "perfect" and "express" with the DRESS vowel, but that in "basket" with /ɪ/ (but with a different first vowel from the dictionary pronunciation given: /'baskɪt/).

  5. There are definitely many people who use a strong DRESS vowel at the start of "express".

  7. It might be worth remembering schwa [ə], schwi [ᵻ], and schwu [ᵿ]; these symbols are used by the OED's editors, and in my own work on Cornish; they're not sanctioned (is that the word?) by the IPA.

  8. Schwa and its allophones are shadow-vowels, apperaing only in unstressed syllable next to a stressed one as a shadow next to a lighted object.
