| Abstract | [Introduction]
The relationship of speech to language has yet to be fully understood. In hope of elucidating this relationship we present a framework which considers speech and language as separate entities in a symbiotic partnership, performing similar functions towards similar ends but a different levels. Intuitive and logical support is given for their separation, and we consider the possible gains in the understanding of language by taking into account that it is usually spoken. Three approaches to the understanding of the role of speech in language are then pursued. The first is to compare the rules of speech (phonology) with those of language (syntac and semantics taken together), the second is to compare the development of speech in man and in the child, and the third is to compare sign language with speech. Given the power of these approaches, we must also remember the holism of the speech-language system. |
