What do you mean voice?
In English grammar, voice doesn't mean the sound you make when you speak. It shows whether the subject of a sentence is doing the action, or having the action done to it.
If the subject is the agent or actor of the verb in a sentence, the verb is in the active voice. When the subject is the target of the action, it is said to be in the passive voice.
