Voiced Sounds:
* Vocal cords vibrate.
* Air is forced through the vocal cords, causing them to vibrate and produce sound.
* These sounds are often described as having a "buzzing" or "humming" quality.
* Examples: "b", "d", "g", "v", "z", "m", "n", "l", "r" (and vowels).
Voiceless Sounds:
* Vocal cords do not vibrate.
* Air is forced through the mouth and/or nose, creating a sound without vocal cord vibration.
* These sounds are often described as "harsh" or "aspirated."
* Examples: "p", "t", "k", "f", "s", "h", "th" (as in "thin"), "ch" (as in "chair").
Here's a simple way to think about it:
* Voiced: Think of the sound of a bee buzzing.
* Voiceless: Think of the sound of a hiss.
How to tell the difference:
* Place your fingers on your throat. You'll feel a vibration for voiced sounds but not for voiceless sounds.
* Try holding your nose while saying the sound. You'll be able to make a voiced sound with your nose blocked, but you won't be able to make a voiceless sound.
Importance of the distinction:
Understanding the difference between voiced and voiceless sounds is crucial for:
* Speech production: This knowledge helps people learn to pronounce sounds correctly.
* Speech therapy: Therapists use this understanding to help people with speech disorders.
* Phonetics: Studying the sound system of languages relies heavily on this distinction.
* Language learning: Knowing this helps learners understand the nuances of pronunciation in different languages.
