The machine pronunciation is indeed somewhat questionable, but petrenko's point stands: there can be no mixing it with "дети" for grammatical reasons. Meantime, Forvo is your friend: https://tinyurl.com/y82dpejm (check all entries, as the first one -- just "дяди" -- is pronounced in a somewhat slower, southern manner).
May I ask for some help to correct my thought processes please? In a previous phrase, "я люблю своих дядю и тётю" the question was asked about case and it was said they were accusitive. OK so for accusative, I thought that masc. it stays the same and fem. goes from я --> ю. So that seems to imply that uncle is feminine. Now in this one, it seems to back this up because the (for want of a better term) negation means that it becomes genitive. So for genitive, again doesn't я -----> ю? And if so, again this is implying that uncle is feminine. I know I am not the sharpest chisel in the tool kit but this has me stumped and I would love some help if someone would like to do so. Thanks in advance to some helpful soul. ))))
Masculine nouns ending with "-я" or "-а" decline the same way feminine nouns with the same endings do. They are masculine in that the adjective, verbs and posessive pronouns applied to them decline by the masculine pattern (like "я люблю свою тётю", but "я люблю своего дядю").
In fact, when Russian kids study grammatical cases, we divide nouns into three types of declensions which are not the same as genders.
1st declension: feminine and masculine nouns ending with "-а" and "-я".
2nd declension: virtually all neuter nouns and masculine nouns with no ending or "-ь" ending.
3d declension: feminine nouns ending with "-ь", neuter nouns ending with "-мя" and some of masculine nouns ending with "-ь".
There are exceptions and special cases of course, but that's the overall pattern. You can see, how those three declensions interact with different cases, here, for example: http://masterrussian.com/aa052000a.shtml
Thank you for a fantastic answer ))) You have actually cleared up a couple of things here )))) With people like you and the other selfless helpers on here, there is no way a person can fail ))) Thank you to all (I won't name as I might offend if I forget one of you - but you know who you are). I hope (I guess in a couple of years) that I can repay this forward by also helping others
