Do you know, Jean’s Aunt Winifred just never goes
/də ˈjuː ˏnəʊ, ˈdʒiːnz | ɑːnt ˋˏwɪnɪfrɪd | dʒəst ˋnevə ɡəʊz ɒn
Simply because she can’t take her cat with her.
/ ˋ-sɪmpli bɪkəz ʃi ˏkɑːnt teɪk hə ˋkæt wɪð hɜː./ 
My old Uncle Ralph won’t come to England because he
won’t be parted from that great hound of his.
/ ˈmaɪ | əʊld ˋ-ʌŋkl ˋ-rælf ˏwəʊnt kʌm tu ˋɪŋɡlənd bɪkəz hi
ˏwəʊnt bi ˏpɑːtɪd | frm ˈðæt ɡreɪt ˋhaʊnd əv hɪz./ 
How terrible to live lives dominated by animals.
/ˈhaʊ ˎterəbl | tə ˈlɪv ˎlaɪvz ˋˏdɒmɪneɪtɪd | baɪ ˎænəmlz./ 
They seem to like it though.
/ðeɪ ˈsiːm | tə ˊˋlaɪk ˌɪt ˏðəʊ./ 
Notice that some of the medial vowels, eg in holiday,
Winifred, dominated and animals are so
short and/or “mumbled” we really can only guess at
It's very likely that the openness of the final vowel of holiday is due to a prosodic process (the
adoption of a fairly "clipped" style) rather than preference for /-i/.
If you listen to the same speaker say Many happy
at Remarks # 9 her final-y sounds are there much more /iː/-like.
Likewise her Germany at People Speaking # 22. The
weakest sounds like /i/ and /ə/ are particularly likely to vary
according to the style of delivery of the speaker so one shd never
decide on what a person's normal quality for such sounds is unless
one's listened to a fair number of instances.
It's often difficult to decide what tones constitute a head
are classifiable as climaxes (or "nuclear") tones. Prescriptive
textbooks tend to simplify recognition of them (tho Crystal 1969 pp 225
etc for all its complexity isnt very satisfying on the topic) and
hardly recognise ones with mixed or complex tones atall. There's
certainly much ambiguity: even so, a sequence like our second sentence
seems rhythmically and semantically to constitute a mixed head plus
Fall climax. Likewise with our “bɪkəz hi ˏwəʊnt bi ˏpɑːtɪd |
frm ˈðæt ɡreɪt ˋhaʊnd əv hɪz./ Fortunately we can
leave such problems to the theorists because they have little practical
relevance. Much the same goes for worrying whether our last sentence
has two climax tones or one: I favour “one” but I
havent actually notated it as the Climb-Fall-Bass-Rise tone I consider
it to be as a gesture towards ease of reading of the tones.
