1. A method of correlating symbols with sounds, wherein at least some of the symbols can correspond to a plurality of sounds and at least some of the sounds can correspond to a plurality of symbols, comprising: providing a dictionary comprising a dendroid hierarchy of branches and nodes, wherein each node represents no more than one of the symbols and wherein each such symbol as is represented at a node has only one corresponding sound associated with that symbol at that node, and each branch includes a plurality of nodes representing a string of the symbols in a particular sequence; automatically using the dictionary to translate an input comprising a given integral sequence of the symbols into a corresponding integral sequence of sounds.
