As a teacher, it took me a long time to realise that though we teach connected speech as something students can say, the first step in learning it is awareness. You need to notice it, or be told it exists and then notice it before you can learn it.Then you can notice the common patterns so when you hear an utterance that somehow has become unintelligible, you have a few cues to help decode it. Even if students can't say it, and believe me they struggle to unlearn the "proper" forms of words when they speak, they do need to be able to listen and recognise it.
But there I was yabbering about something I k'n confidently deal with, my forte, English. When you're the teacher and master of your language you can smugly say how it is with a smile and if there is resistance, you k'n just say that that is what English is and that it has to be accepted. But after I knock off work, I remove my English right shoe and put on my Cantonese left shoe and suddenly begin yabbering in a less consistent, less assured way. In earlier blogs, I've mentioned that Qingyuan Cantonese has routine connected speech with particular words. I'd adjusted to this because they were particular high frequency words. They were set contractions just like English has "won't" "aren't/ain't" "can't" etc.
I knew that there were some mild features in Guangzhou Cantonese too, but not to the same creation of set contractions. Now, watching a HK crime drama I've scratched deeper by noticing the more garden variety connected speech which is more subtle, quick and insidious. And so the left foot has started kicking. The contractions I've only just gaining an ear for a quick. The Cantonese word for but is "daan6 hai6" (numbers denote tone) only now have I realised in the TV shows that it's mostly said as "Daa'ai6" unless said deliberately. Another 3-4 changes I noticed in about 20 minutes of watching all because my mind was switched on to inconsistencies and unintelligible sequences that the mandarin subtitles hinted as being intelligible phrases.
There are inherent difficulties in understanding connected speech: the phenomenon happens more with faster speech. That means that fast speech is not just more difficult because of the pace but comprehension is also obscured by these transformations of sound. And couple that with the tendencies of speakers to go from fast to slower in a turn at speaking (often this happens in language where the key information is later in the sentence so the first part which frames it is hastily rushed through). That means for a learner watching a TV series, when another person starts speaking they'll throw high speed sentence starters before saying their key information. That helps for understanding gist if you ignore the first few words they say, but often the initial burst hits me like a drawer of flying knives, causing me to duck the rush of meaning that quickly ceases by the time I get the composure to listen onward.
Learning language you don't just need patience but a degree of foolhardiness to stand strong in the rush of meaning and take it in.
