While I was working on my pronunciation drills about star signs - Elementary WS2-08, I put pronunciation practice into different layers - a slide with weak form, liaison and assimilation, another one for sentence stress and the third one for intonation and rhythms. But assimilation/elision tricked me as in the phrases - "bad points" and "a favo(u)rite day of the week".
Though assimilation differs from elision by modifying the end consonant in the proceeding word instead of omitting it, it is hard to tell the difference between the two when it modified consonant is the same with the beginning one in the following word, e.g. "good boy" - /ɡʊb bɔɪ/ or "good girl" - /ɡʊɡ ɡɜːl/. Adrian Underhill's examples in this Sound Foundation didn't bring me any questions in understanding it as he explains that most of the examples are listed in the book, until "bad points" and "favorite day" came to me. First of all, they are not listed there as /~~~d p~~~/ and /~~~t d~~~/. Scott Thornbury has a brief definition about the two terms, as elision "is common when two plosive sounds occur together". But exceptions are all over the place in Sound Foundation.
So, I am writing to ask for your opinions.
"bad points" 1./bæp pɔɪnts/; 2./bæ pɔɪnts/
"favorite day" 1./ˈfeɪvərɪd deɪ/; 2./ˈfeɪvərɪ deɪ/
Which ones do you think they are if we have to tear assimilation apart from elision?
