Should we reopen this (very old) question?

I can, but I want to see what the community thinks.

@M.A.R. I know all about SmokeDetector already. What I don't know about is this "you have made a lot of accounts" thing. Have I? :-)

Oh, do you mean how I have accounts on lots of SE sites?

Since they all share a login and session, I think of them as one account, and sometimes I forget they're displayed as though they're separate accounts.

So it took me a moment to figure out what you meant.

@DamkerngT. I don't see an /ɪ/ in your transcription. I only see /aɪ/, which is a single phoneme.

Well, phonemes don't exist acoustically.

Those are phones.

BrE /aɪ/ doesn't exactly contain the sound of /ɪ/, in any case.

/ɪ/ is slightly backer than the end of /aɪ/.

Phonemically, /aɪ/ is a single sound and cannot be split.

Not exactly, though.

/aɪ/ doesn't end up quite where /ɪ/ is.

So in a very real sense, /aɪ/ does not contain /ɪ/.

Right, there's a range of realizations.

> The diphthong [aɪ], as in high, buy, moves toward a high front vowel, but in most forms of English, it does not go much beyond a mid-front vowel. Say a word such as buy, making it end with the vowel [ɛ] as in bed (as if you were saying [baɛ]).

> A diphthong of this kind probably has a smaller change in quality than occurs in your normal pronunciation (unless you are one of the speakers from Texas or elsewhere in the South and Southwest who make such words as by, die into long monophthongs—[baː, daː]).

> Then say buy, deliberately making it end with the vowel [ɪ] as in bid. This vowel is usually slightly higher than the ending of this diphthong for many speakers of English. Finally, say buy with the vowel [i] as in heed at the end. This is a much larger change in quality than normally occurs in this word. But some speakers of Scottish English and Canadian English have a diphthong of this kind in words such as sight, which is different from the diphthong that they have in side.

(A Course in Phonetics, 6th ed. p.92)

They also write:

> In English, the first part of the diphthong is usually more prominent than the last. In fact, the last part is often so brief and transitory that it is difficult to determine its exact quality. Furthermore, the diphthongs often do not begin and end with any of the sounds that occur in simple vowels.

@DamkerngT. The passages I quoted, by the way, don't mention anything about phonemes.

They're about phonetics.

Ladefoged was one of the most prominent phoneticians in the history of linguistics, so I don't think he would make the mistake you suggest.

I'm not saying everything he wrote was perfect, but if anyone knew the difference between phonemes and phonetics, it was Peter Ladefoged :-) He was extraordinarily precise in his descriptions.

@Færd Right dislocation is only felicitous in certain contexts, and you haven't given any context.

Since in this case you're dislocating a proper name, without context to make sense of it, Fred looks like a vocative.

You can fix that by adding that: He doesn't have a chance, that Fred.

I think that sort of colloquial right dislocation is somewhat more characteristic of BrE than AmE.

Also, the second example seems like left-edge deletion following right dislocation, so it doesn't seem substantially different from the first to me.
