Using "it" as a direct object pronoun?

Here is a short exchange I've attempted to translate to Spanish

Q. "Do you know any English?"

A. "Yes, I can speak it."

My attempt at Spanish for the above:

P. "¿Sabes alguna del inglés?

C. "Sí, yo puedo hablarlo."

In particular, is the above response precisely correct? I'm unsure about using the direct object pronoun (lo) that way--hablarlo. Should it be something else?

Mil gracias.
