The voice of a verb in grammar describes the relationship between the action (or state) expressed by the verb and the participants identified by its arguments (subject, object, etc.). The verb is in the active voice when the subject is the agent or doer of the action. The verb is said to be in the passive voice when the subject is the patient, target, or undergoer of the action. The verb is in the middle voice when the subject both performs and receives the action expressed by the verb. Diathesis is another term for voice.
The subject and direct object switch grammatical roles when converting an active-voice clause to an equivalent passive-voice construction. The direct object is elevated to the status of subject, while the subject is demoted to the status of (optional) adjunct. The mouse is the direct object in the active-voice version of the first example above, but it becomes the subject in the passive version.
