>>51400320>>51400369>But yes, fwiw, I normally do not put my tongue right up against my teeth for the sounds. I put my tongue near the top of my teethThis right here is an admission that you are not pronouncing English "th" correctly (even in your second recording where you says "Matthew"), where I hear you pronounce the "th" as a plosive and not a fricative).
English "th" is pronounced by your putting your teeth on your tongue (not your tongue against the bottom or back of the teeth (like ट or त or English t), nor the ridge behind the teeth (like ठ or थ). You press your teeth down on the surface of your tongue, and then blow air (the tongue doesn't need to move or seperate from any surface, because it isn't pressing against anything).
When you pronounce any of ट, त, ठ, थ, you press your tongue against some surface (teeth or ridge behind teeth), right? That's also the case with English t (in that case, it's the teeth, not the ridge behind it), but NOT English "th". If you are pressing your tongue against any surface like the teeth or ridge, you are already' not pronouncing "th" correctly (as any English learning video will show you - they all show themselves placing their teeth on top of the surface of their tongue). And then, when you actually make the English Th sound, you only have to blow air through the teeth that are on top of your tongue. You don't move your tongue or teeth whatsoever, you you HAVE to do in other to pronounce ट, त, ठ, थ, and English t (since you are pressing your tongue against a surface, building pressure, and then you have to break the connection between your tongue and that surface to release the sound. Again, and English learning video will show you that when they pronounce the "th" in English, the tongue doesn't move - the teeth are in contact with the tongue for the entire duration of the sound, unlike English t or ट, त, ठ, थ
