A speech sound that is produced as a stream of air that is not obstructed or blocked
in any way by the vocal organs, but only modulated by the position of the tongue, lips, etc.

littera vocalis, literally "vocal letter," from
→ vox "voice," cognate with Pers. âvâ,
→ phone, vâžé, → word.
Xodâvâ, literally "self-voice," as Ger. Selbstlaut, from xod-,
→ self-, + âvâ, → phone.
