Voiced consonants are sounds produced when the vocal cords vibrate during articulation. Examples include the sounds represented by the letters b, d, g, v, z, and m. These consonants are typically found in the middle or at the end of words, such as in dog or have. In contrast to voiced consonants, there are voiceless consonants, which do not involve vocal cord vibration. Examples of voiceless consonants include p, t, k, f, and s. Understanding the difference between voiced and voiceless consonants is essential for proper pronunciation and phonetics.
