Explanation:
In grammar, the term <em>voice</em><em> </em>refers to the relationship between the action or state expressed by the verb and the participants expressed by the subject, object, and other elements of the sentence. There are two voices in English:
The active voice - the sentence has a subject that acts upon its verb (e.g <em>John is reading a book</em>).
The passive voice - the subject is the recipient of a verb's action (e.g. <em>The book is being read by John</em>).
