There are fundamentally two voices in English which are the active and the passive voice. To identify each voice, it is highly recommended to look at the subject in each sentence. If the subject does the action then it is obviously the active voice. For instance, my mom waters the flowers every morning. In this sentence the subject mom does the action of watering the flowers. So the statement is in active voice. On the other hand, in passive voice the subject receives the action. For example, flowers are watered every morning by my. As we can see the subject which is the flowers do not initiate/cause any action but receives the action hence it is in passive voice.
Here are the forms to use when
changing sentences from active to passive voice.
