Pronounce "ts"?

Question

I would like to get help with pronouncing "ts", words and phases such as, "eaTS", "LeT'S", "rats" etc.

Before, when I pronounce "ts", I usually push my tongue to the teeth(tip touching teeth fully), and the sound aspire almost right between the gap of the teeth with the tongue touching it.

But now, when I think of it carefully, I think its incorrect. Because if I pronounce t followed by s slowly, I realise my old way was wrong.
Should the sound aspire on the "front meat of the upper jaw", rather than at the front where the teeth are? In other words, the "ts" sound should be aspired a little bit behind the teeth, and the tongue shouldn't touch the front teeth when pronouncing "ts"?

Can native speakers tell me which one is correct(first/second), or neither? Thank you very much.

Answer 1

I push my tongue forward from the front meat part, to the top front teeth, and then down toward the bottom teeth, aspiring to create the 's' sound when my tongue touches the back of my lower teeth, almost letting a little saliva create a bridge between the roof of my mouth and my tongue as I bring it to my lower teeth. To pronounce the 's' sound, your tongue should should be drawn downward toward the bony part of your lower jaw beneath your tongue, but lifted in the back. The tip of your tongue should not touch anywhere on the top portion of your mouth to pronounce 's' in 'ts'.

Answer 2

I just put the tip of my tounge on the top of my mouth close to my front teeth to pronounce it.

Answer 3

you would just pronounce the word and then add sa like eat- sa. after you pronounce the word your tongue would go down to the back of your lower teeth. She pet-sa her cat-sa often.

Answer 4

Say the T and then the S.
