The organ of speech is an instrument of the physical mental or expressive externalising mind. <ref>http://incarnateword.in/cwsa/28/the-parts-of-the-body-and-the-centres#p7</ref>

Speech comes from the throat centre, but it is associated with whatever is the governing centre or level of the consciousness—wherever one thinks from. If one rises above the head, then thought takes place above the head and one can speak from there, that is to say, the direction of the speech is from there.

.. speech and the five senses of knowledge are the instruments of the mind. Prana, the life-force in the nervous system, is indeed the one main instrument of our mental consciousness; for it is that by which the mind receives the contacts of the physical world through the organs of knowledge, sight, hearing, smell, touch and taste, and reacts upon its object by speech and the other four organs of action; all these senses are dependent upon the nervous Life-force for their functioning. The Upanishad therefore begins by a query as to the final source or control of the activities of the Mind, Life-Force,Speech,Senses.
