I was wondering whether anyone could help me distinguish how to pronounce tone 4 (mostly low flat) and tone 3 (mid flat).
I read in tone 4, you should feel your throat vibrate. Honestly, I have my finger touch my adam's apple and try to feel the difference but I don't feel it between 3rd and 4th. Is there any way to better work out my tones alone? The only thing I do about my 4th tone is shorten my 3rd tone. Thus, 4th tone to me = 3rd tone, but in a shorter burst.
How can I distinguish them?
