What are active voice and passive voice sentences?

• In English Grammar, the voice of a sentence is either the active voice or passive voice.
• The main difference between the voices is the subject-verb strategy.
• A sentence in which the subject is acting on the verb is said to be in active voice.
• A sentence in which the verb is acting on the subject is said to be in passive voice.
• Hence, when we change the voice of an active sentence into a passive one, the subject of the active voice sentence becomes the object of the passive voice sentence.
