- Voiced sounds - your vocal folds vibrate
- Voiceless sounds - you push air out, but your vocal folds don't vibrate
You can test this by putting your fingers on your throat. If you feel your throat vibrate when you say the sound, it is voiced. If you don’t, it is voiceless.
Let’s try it. Put your fingers on your throat and say, “B, D, G.” If you feel your fingers vibrate, that means these sounds are voiced. Did you feel them vibrate?..Yes, these are voiced sounds!
ALL vowels are also voiced.
Now let’s try to feel the difference between that and voiceless sounds. Put your fingers on your throat and say, “P, T, K.” You can’t feel your fingers vibrate, can you? That means these sounds are voiceless.
