Oralism is the education of deaf students through oral language by using lip reading, speech, and mimicking the mouth shapes and breathing patterns of speech. Oralism came into popular use in the United States around the late 1860s. In 1867, the Clarke School for the Deaf in Northampton, Massachusetts, was the first school to start teaching in this manner. Oralism and its contrast, manualism, manifest differently in deaf education and are a source of controversy for involved communities. Oralism should not be confused with Listening and Spoken Language, a technique for teaching deaf children that emphasizes the child's perception of auditory signals from hearing aids or cochlear implants. Fray Pedro Ponce de León (1520-1584) is often credited as the inventor of deaf people education. Later, Juan Pablo Bonet (c. 1579–1633) will publish Reducción de las letras y arte para enseñar a hablar a los mudos, which circulated widely as a foundation method for teaching. Bonet was an oralist that defended the use of words to communicate but he also favoured the use of certain hand sign language. Since the beginning of formal deaf education in the 18th century in the United States, manualism and oralism have been on opposing sides of a heated debate that continues to this day. Oralism as the systematic education of deaf people began in Spain in the mid-1500s and was the byproduct of socioeconomic motives. The church barred deaf people from Holy Communion because they could not confess aloud. Deaf people were also prohibited from inheriting their family's wealth; therefore, to preserve the family wealth, deaf heirs in Spain were sent to Pedro Ponce de Leon after hearing that he taught a deaf man to talk in San Salvador Monastery in Oña. Oralism provided members of the privileged classes with deaf children a way to channel their children's education and an opportunity to keep them away from the deaf community. Speaking has been associated with the higher classes and higher intellect, and the perception of signing has been the opposite.
