Labio-dental

Speech sounds formed between the lower lip and the upper central incisors, as in the fricatives /f/ and /v/, but rarely with the upper lip touching the lower front teeth.  The former is a voiceless labio-dental fricative (e.g., fan) and the latter a voiced labio-dental fricative  (e.g., van).  A labio-dental approximant is type of consonant, with similarities to the English double-u, pronounced with teeth and lips maintained in a position so as to articulate the letter vee.  It is relatively frequent in Dutch, an example being wang (cheek) and pronounced ‘vang’.  As with lingua-dental sounds, the ability to master it must await the appearance of the first teeth.
