Is any other name for vowels?

While "vowels" is the standard term for the sounds that are produced without any obstruction of airflow in the vocal tract, there aren't really any other common names for them.

However, you could refer to them using these less common terms:

* Open sounds: This emphasizes the lack of obstruction in their production.

* Voiced sounds: This highlights that they are always voiced (meaning the vocal cords vibrate).

* Sonorant sounds: This refers to their relatively open and resonant quality.

It's important to note that these alternative terms are less precise and might be used in specific linguistic contexts. In general, "vowels" remains the most common and easily understood term.
