Disorders of speech, language and communication involve some degree of dysfunction of auditory perception, auditory decoding, or auditory memory. When there is no auditory pathology or pathology of the speaking apparatus, the Tomatis method of sound therapy, together with speech therapy, can contribute to the faster development or improvement of speech and language.
Communication difficulties may include a difficulty to perceive speech or prosody. Some people find themselves unable to use their voices effectively, due to a lack of control over the various components of the intonation, inflection, or volume of speech. Lacking control, the voice will be perceived as aggressive, cold, or flat by the person being addressed.
