What does r and b sound like?

The "r" sound is typically a voiced consonant that involves the vibration of the vocal cords. It is produced by slightly raising the back of the tongue towards the roof of the mouth.

The "b" sound is a voiced consonant that is produced by closing the lips together and then releasing them while simultaneously voicing or vibrating the vocal cords. It is similar to the "p" sound, but with the addition of voicing.
