In turn 1 it's completely normal for a speaker to omit the final plural /s/ of a word ending -st.
In turn 3 there's only one /s/ which can't necessarily be said to belong more to the end of seems than the beginning of so.
In turn 4 the final consonant of ask
seems unclear. If we think it's /k/ there's been an elision of
final /t/; if it's /t/ then it's quite normal for the past of ask to be /ɑːst/ with elision of /k/.
In turn 10 the omission of the first personal pronoun 'I' before
a verb (here 'tell') is common in very colloquial speech.
In turn 11 the weakform of there's produced
by shortening of the vowel to /e/ isn't very unusual despite the fact
that none of the dictionaries etc recognise it as a weakform. Very usually heard in the
sentence "They're off ", exclaimed when a horse race starts, is another such unlisted weakform.
