voiceless c

Rule Core

Voiceless consonants are produced without vocal cord vibration, relying on airflow friction or release, such as /p t k f s/. In phonics, mastering voiceless sounds improves decoding accuracy and spelling awareness. Common letters include c, s, f, t, p, k in specific environments.

Articulation Guide

Keep the vocal cords relaxed and silent. The tongue approaches or touches the articulation point, while the mouth remains relatively tense. Airflow is strong and audible, especially for /s/ and /f/.

Pitfall Alert

Do not confuse weak stress with voicelessness. Also watch for letters that change voicing depending on position.
