1a) Jim: Hullo, Margaret. Had a good holiday?
1b) `hᴧˏləʊ, mɑgrət. ˈhad ə gʊd ˏhɒlədɪ
On we go with the second line:
2a) Margaret: Hullo, Jim. Yes. Very nice, thanks.
2b) `haləʊ, ˏʤɪm. `jes. `veri naɪs ˏθaŋks.
Listen to the audio snippet:
My impression of 2a) is this:
2c) `hæləʊ, ˏʤɪm. `jes. `veri naɪs ˌθæŋks.
The speaker's TRAP vowel is closer to CV3 than to CV4, which justifies the use of the ash symbol. I agree with all the tonemarks but one: "thanks" is said with a BASS tone. Here's the pitch contour of the whole line:
(There are some artefacts in the pitch contours; some of the pitch movements do not correspond with the auditory impression etc. See also Jack Windsor Lewis's blog no. 479.)
