And he adds that you do not get that more emphatic sound in, for
instance, the conjunction _nec_.

Si autem _nec_ conjunctionem aspiciamus, licet eadem littera finitam,
diversum tamen sonabit.

And again:

Ut dixi, in pronominibus C littera sonum efficit crassiorem.

Pompeius, commenting upon certain vices of speech, says that some
persons bring out the final C in certain words too heavily, pronouncing
_sic ludit_ as _sic cludit_; while others, on the contrary, touch it so
lightly that when the following word begins with C you hear but a single
C:

[Keil. v. V. p. 394.] Item litteram C quidam in quibusdam dictionibus
non latine ecferunt, sed ita crasse, ut non discernas quid dicant: ut
puta siquis dicat _sic ludit_, ita hoc loquitur ut putes eum in secunda
parte orationis _cludere_ dixisse, non _ludere_: et item si contra dicat
illud contrarium putabis. Alii contra ita subtiliter hoc ecferunt, ut
cum duo C habeant, desinentis prioris partis orationis et incipientis
alterius, sic loquantur quasi uno C utrumque explicent, ut dicunt multi
_sic custodit_.

D, in general, is pronounced as in English, except that the tongue
