/o/ sound on the end

[Amigoo]

Hello.
I worked with /o/ last sound. But i don't know I got it. When I pronunce words with last o I often hear that sound clear, like first O in oficina for example. But Speakers pronunce it like short o. Check my work pls

The vowel 'o' is always pronounced the same, whether stressed or not.
If you hear native speakers saying anything else, it is either regional or habitual for them only.
ALL Spanish vowels are pure. They do NOT change based on whether they are stressed or not.

Do I pronunce it correct?

[Rusty]

You pronounced it correctly.

One thing I have found is when dealing with native Spanish speakers who have lived in a non-Spanish speaking area for many years, their pronunciation and word choices are often affected quite a bit by the dominant language of the region. And this goes for any language. So as you're learning, just be careful what you internalize as "correct". Verify things using a variety of sources.
