sound-blending and sound-graphic

Out of the 'music brochure' by Ptaah and Billy:
Unfortunately, however, in their habitual linguistic form, many mothers and fathers try to draw the attention of their newborn and then of the growing child through sound-blending and sound-graphic representations and unclear exaggerations and produce a one-sided monologue which they erroneously consider to be communication, but therethrough, with their ‘baby language’, put more distance between themselves and the child, rather than a valueful relationship and connection.
