Wobé is known for claims that it has the largest number of tones (fourteen) of any language in the world (Bearth & Link). However, this has not been confirmed by other researchers, many of whom believe that some of these will turn out to be sequences of tones or prosodic effects (Singler 1984, Newman 1986), though the Wèè languages in general do have extraordinarily large tone systems.

[Newman believes Singler is a valuable counterweight to Bearth & Link, but does not accept all his criticism; he accept the Wobe 43 toneme, for example, though believes it should be analyzed as /32/ (all tones being off by 1 compared to related dialects).]
