I think that this reconstruction is better (and
correct):

Proto-Altaic *k'ele- 'tongue'

Proto-Turkic *kele- 'to speak, to talk'
Proto-Mongolian *kele- 'tongue'
Proto-Tungusic-Manchu *xiln-u- 'tongue'
Proto-Korean *ka-ro- 'to say'

(v. Starostin, Etimological Database and Altaiskaia
problema i proisxozhdenie iaponskogo iazyka)

PA PT PM PMT PK (PJ)
*k' *k *k *k/*x *k (*k)

PA PT PM PMT PK (PJ)
*e *e *e *e/*i *a (*i/*@)

The Starostin reconstruction *k'ia-li- are very odd,
and it breaks his own rules (for this I have written
these correspondences). Nevertheless, his resources
are very, very good.
