Is Speech the Same as Language?
Sometimes people talk about a child's speech, when they really mean language. Although speech is an integral part of language, the words are sometimes used interchangeably. Speech usually refers to the pronunciation of words (articulation), the easy flow of speech (fluency vs. stuttering), and the quality of the sound of one's voice (normal sounding vs. hoarse, harsh, or unusual in pitch or volume). Speaking requires us to translate our thoughts into sound sequences that are understood by others. The thoughts and the sentences to express them is language; the actual sounds are speech.
