Thai numbers are written in base ten and left to right (i.e. the same way that western numbers are written), it's just the glyphs that are different. Most of the time you will see western numerals even where everything else is in Thai.
The initial ‘S’ sound is halfway to a ‘Z’ sound.
This leads to ‘Bier sing song cup’ (two Singha Beers please).
This is ‘psalm’ with a silent ‘P’.
It’s a long ‘ha’, like ‘h-ahh’.
The ‘P’ is very nearly a ‘B’ sound. Imagine saying the first half of ‘better’.
Like the word ‘gown’ without the ‘N’.
