The '''sense of speech''', also called '''word sense''' or '''sense of words''', is one of the twelve physical [[sense]]s [[Rudolf Steiner]] spoke of in his teaching of the senses. Through the sense of speech we perceive spoken or written [[speech sound]]s and the [[word]]s formed from them as [[language]]. This distinguishes it from the [[sense of hearing]], through which we perceive sounds but not directly words.

Rudolf Steiner has repeatedly pointed out that the so-called [[motor nerve]]s are in reality also [[sensory nerve]]s. By not making certain gestures with my locomotor organism, but by holding them back, I understand what is expressed in words. One's own speech, on the other hand, relies only on a part of the locomotor organism, namely the larynx and the adjacent organs.

This is not the physical organism of life, it is the physical organism of the ability to move. This is also the organ of perception for language, for the words that the other sends to us.

The sense of speech, also called word sense or sense of words, is one of the twelve physical senses Rudolf Steiner spoke of in his teaching of the senses. Through the sense of speech we perceive speech sounds and the words formed from them as language. This distinguishes it from the sense of hearing, through which we perceive sounds but not directly words. In addition, language can also be perceived through writing, gestures, facial expressions, physiognomies and so on.

„The sense of speech: this again has nothing to do with the formation of our own language, nothing to do first of all with the ability that underlies our own speech, but it is the sense for understanding what is spoken to us by the other person.“ (Lit.:GA 170, p. 240)

The sense of speech as an independent sense

„Likewise, when we listen to words and hear a meaning in the words, it is based on something quite different than when we hear the mere tone, the mere sound. Even if it is more difficult at first to prove a human organ for the sense of words than it is to prove the organ of hearing for the sense of sound, he who can now really analyse our whole field of experience must nevertheless realise that within this field of experience we must limit on the one side the sense of sound and tone, the sense of sound, and on the other side the sense of words.“ (Lit.:GA 206, p. 10)

„It is certainly self-evident that in the perception of a spoken word a complicated activity of judgement, that in the process extensive processes of the soul come into consideration, which cannot by any means be assigned the word 'sense'. But in this sphere there is also something simple and immediate which, before all judgement, is a sensation, just as a colour or a degree of warmth is such a sensation. A sound is not merely felt according to its tonal value, but something much more inner than the tone is perceived with it. If one says that the soul of a body lives in sound, one can also say that this soul is revealed in sound in such a way that it is detached, freed from the physical, and appears with a certain independence. Because the sensation of sound is prior to judgement, the child learns to feel the phonetic meanings of words earlier than it comes to the use of judgement. The child learns to judge from language. It is quite justified to speak of a special sense of sound or language. The recognition of this sense is difficult only because the immediate sensation of what is revealed in the sound is usually accompanied by the most varied activity of judgement. But an exact introspection shows that all hearing of what is given in sounds is nevertheless based on an equally direct, non-judgemental relationship to the being from which the sound emanates, as is the case when an impression of colour is perceived. It is easier to understand this fact if one realises how the sound of pain allows us to experience the pain of a being directly, without any consideration or the like interfering with the perception. - It must be taken into consideration that the audible sound is not the only means by which such inwardness is revealed to man as is the case with the speech sound. Gestures, facial expressions, physiognomies, too, ultimately lead to something simple and immediate, which must be counted as much in the domain of the linguistic sense as the content of the audible sound.“ (Lit.:GA 45, p. 27f)

The organ of the sense of speech

The sense of speech is based on our resting organism of movement, insofar as the nerves for the locomotor system emanate from our central nervous system. Rudolf Steiner has repeatedly pointed out that the so-called motor nerves are in reality also sensory nerves. By not making certain gestures with my locomotor organism, but by holding them back, I understand what is expressed in words. One's own speech, on the other hand, relies only on a part of the locomotor organism, namely the larynx and the adjacent organs.

„And insofar as we have the strength to move, to be able to carry out all the movements we have through our inner being, for example when we move our hands, when we turn our head or move it from top to bottom, we carry out movements from within. So in so far as we have these powers to set the body in motion, there is a physical organism underlying this movability within us. This is not the physical organism of life, it is the physical organism of the ability to move. This is also the organ of perception for language, for the words that the other sends to us. We could not understand words if we did not have a physical organism of movement within us. Truly, inasmuch as the nerves to our whole process of movement proceed from our central nervous system, therein lies also the sensory apparatus for the words that are spoken to us.“ (Lit.:GA 170, p. 243)

„If we want to look at what actually underlies speech, we can first go back to the human soul life, in which the origin of speech undeniably lies for everyone who is sensible. Speech originates in the soul, is kindled by the will in the soul. Without wanting, that is, without developing an impulse of will, no spoken word can come into being. If one observes the human being from a spiritual-scientific point of view when he speaks, something similar happens in him as happens when he understands what is spoken.

In fact, the human body reacts to heard speech with characteristic holistic micro-movements of the whole muscle system, first discovered by the American researcher William S. Condon[1].

„Condon came across a hitherto unknown process that was lawfully linked to speech, but could only be uncovered with modern technology: During the process of speaking, he discovered, the speaker's entire body performs tiny movements that escape ordinary observation.

Various diseases such as Parkinson's disease, autism or a cerebral movement disorder ("spasticity") lead to an asynchrony between speech and these micro-movements.

The shape-forming forces of articulated spoken language form characteristic shapes in the exhaled breath, which can be made visible by suitable methods, such as Toepler's schlieren optics. Johanna F.

The specialisation of the sense of words by Ahriman

In Lemurian times we were predisposed to understand words but not to speak words. This sounds paradoxical at first, but it is not.
