Oh yes! Sorry, forgot! Prepositions are very difficult in English, so don't worry, but it should be:
speak + to + somebody ('speak with' is when it's a serious talk)
e.g.
I spoke to him.
ask + (somebody) + infinitive with 'to' (no preposition)
e.g.
I asked him to help me.
translate + (something) + into + something (movement - like get into and out of a car)
e.g.
Can you translate this into Spanish?
Also, this is all
British English. American English is different in many ways. Both are acceptable, as are Australian, Canadian, Irish etc.
Sorry for the technical stuff
