  The language competition model of Viviane de Oliveira et al is modified by
associating with each language a string of 32 bits. Whenever a language changes
in this Viviane model, also one randomly selected bit is flipped. If then only
languages with different bit-strings are counted as different, the resulting
size distribution of languages agrees with the empirically observed slightly
asymmetric log-normal distribution. Several other modifications were also tried
but either had more free parameters or agreed less well with reality.
