No, I didn't omit the i. I picked up the Scots Dictionary that Jo gave me, thinking I might find an interesting word for Miscellany, but stopped at the pronunciation guide and got jolted to a halt. It says:
ng in Scots, eg hunger, ingle, ingan, is almost always pronounced as in English sing, not as in English single . For the life of me, I cannot hear any difference between the two ng's. What is it that I'm not knowing? As far as I'm concerned, the first four letters of both are pronounced exactly the same way; it's just that a hard g gets added to form the second syllable of single.

Yup!

That is the difference. Compare singer and finger.

It sounds to me like I add an extra 'g' when saying
sing~gle and fing~ger.
But not when saying sing er!

Is that the hard G working?

And note that the common dialect feature, made famous by, but certainly not exclusive to, Sarah Palin, known as G dropping is not actually dropping a G but changing the NG sound (IPA ŋ) as in sing to an N sound. The G is dropped in written representations of this feature, e.g., "I'm lookin' at you," vs. "I'm looking at you."

Nga is the third letter in the Cook Island alphabet.
Try saying it like: singah

Got it, I think. But I've been told, by somebody who ought to know, that the Vietnamese Nguyen is pronounced win. [shrug] Quite a difference.

Interesting. I learned Nguyen as in downwind.

And I learned it as /ŋwɛn/ as in sing when. This can be hard for many Anglophones since we don't have the ng /ŋ/ phoneme in a word initial context.

Some Australian telephone message systems have introduced 'voice recognition computer software' this adds a different dimension to messages I receive when the spoken word is misinterpreted...sometimes I have no idea what the message was about!

I am thinking accents must make it difficult to understand some words.
