What type of sound is represented by the letter combination 'wh'?

The letter combination 'wh' represents a sound that can be characterized as unvoiced, particularly in words like "what" or "where." The sound produced is a voiceless labio-velar fricative, which means that it's made without the vocal cords vibrating. This places it in the category of unvoiced sounds rather than continuous ones, which are produced with a consistent airflow. Continuous sounds, like 's' or 'z,' involve longer durations of airflow, often accompanied by vocal cord vibration, which does not occur with 'wh'. Hence, identifying 'wh' as a continuous sound is not accurate. The proper categorization emphasizes its unvoiced nature and the specific articulation required to produce the sound correctly.
