      voiced th is like this, that, mother

      unvoiced th like thick, thimble, thirty

      notice how the voiced th has a buzzing vocalization during the th sound, you can feel your teeth buzzing as you say the th in this

      but when you pronounce thirty that buzzing is absent and the first buzzing starts with the i (the vowel is the first voiced part).
