Entries with more than one primary stress marker #2
Description
Maybe you are already aware of this, but there are a lot of words (about 1000 it seems) that have more than one primary stress marker. For example "duration":
DURATION D UH1 R EY1 SH AX N
For this word, other dictionaries like this: https://www.merriam-webster.com/dictionary/duration or this: https://en.wiktionary.org/wiki/duration only show the second syllable with primary stress. So it should be D UH0 R EY1 SH AX N.
On the other hand there are also words like "alongside":
ALONGSIDE AX L AO1 NG S AY1 D
where for example this dictionary: http://www.learnersdictionary.com/definition/alongside agrees that both the second and the third syllable should have primary stress. Presumably because in a sense it's actually two words that are written as one. So, it's not as simple as saying all double primary stress entries are wrong.
I actually started going through all those entries to de-duplicate the primary stress but when I saw how many there are, I gave up. What do you think about this? (Maybe the stress markers are not that important to you, which I could totally understand.)
