IPA transcription for project as a verb: /prəˈdʒɛkt/
while the standard pronunciation across different accents is heard as "pruh-ject", in practice I sometimes hear something more like "pro-ject" rather than "pruh-ject" and more of a əʊ sound as in /prəʊˈdʒɛkt/
it's the same sometimes for words with a ə
present where there is, or before the beginning of lexical stress:
/əbˈtruːd/ (ob-trude and uhb-trude)
/prəˈtruːsɪv/ (pro-trucive and pruh-trucive)
for words like these (or at least the ones in my question if it's too broad an ask) are the alternative pronunciations I've listed also valid and acceptable ways of pronouncing them?
