Lame is spoken in Benoue Department of Cameroon
along the Chad border. Non-high vowels have a rounded
schwa variant in initial syllables of some disyllables and
reduplicated forms. Vowels are nasalized before velar
nasal and the nasal is dropped in some forms. Sachnine
(1982) suggests positing a series of nasalized vowels.
There are 3 level tones, but strong dependence between
initial consonants and tone in verbal forms. Intervocalic
voicing of obstruents is strongly influenced by initial
voicing.
