It should actually be, "With whom would you like to speak?". Only a
compleat grammar and usage nutter would teach that form as "correct" to
a non-native speaker, however.
Corpora show that "Who would you like to speak with/to?" is far more
common in ordinary telephone conversations, both US and UK. I, and most
native speakers, would take "Whom would you like to speak with?" as
being redolent of the stink of the most pompous 17th cetury
prescriptive grammarians, who invented "whom" as a way of civilizing
the uncivilized tongue they were attempting to turn into a national
language. We might even find "Whom do you want to speak with?" funny.
"Who do you want to speak to?" is just fine, but I would still use the
more polite "Who would you like to speak with?" and teach it to
learners as a primary form.
luc.chantal.petitjean, are you asking us if the statement is correct or
if we could possibly teach you English? The statement is just fine, and
you should have some luck finding someone to help you.
