1. A two-tier method of converting an audio input, comprising words maade up of various sounds in a spoken sequence, into a visible form, comprising a sequence of corresponding phonemes, said method comprising the steps of: (a) breaking down the spoken sequence of sounds into syllabits, each syllabit comprising a group of classes of sounds; (b) grouping the syllabits into syllabit groups, each syllabit group defining corresponding possible words; (c) providing, for each of said possible words corresponding to each syllabit group, a respective skeletal sequence of phonemes comprising a corresponding grouping of phonemes; (d) determining, for each distinctive syllabit group, the phonemes occurring therein so as to develop an input sequence of phonemes for each syllabit group; (e) comparing the input sequence of phonemes for each syllabit group with the respective skeletal sequence of phonemes of each of the corresponding possible words so as to determine, with reference to the phonemes in each grouping of phonemes, which possible word has a skeletal sequence of phonemes which contains, in a given sequence, phonemes all of which are found, in said given sequence, in the input sequence of phonemes, thereby identifying each of said words of said audio input; and (f) providing said identified words of said audio input in said visible form.
