In our daily conversation, we use a set of words organized into phrases as a linguistic message. The utterance contains, however, additional information which is specified for a specific situation of verbal communication, to identify the speaker, convey the speaker's emotion, as well as intention and expectation. While such extra-linguistic information is crucial for effective conversation, speech technology has concentrated its effort on the capability of machines to produce and understand linguistic information, treating other phonetic information as both extraneous and disturbing factors. We need a new theory that can represent lively utterances as observed naturally. The Converter/Distributor (C/D) Model is a phonetic theory for representing realistic speech utterances. Words and phrases are represented abstractly as linear strings of syllables rather than consonants and vowels, and each syllable is specified as a set of features rather than a sequence of phonemic segments. Experimental observations of how conversational speech is produced as the articulatory processes of tongue and jaw movements have been interpreted by the Converter/Distributor (C/D) model, gradually revealing principles and strategies of speech organization. Widely variable utterance characteristics are now to be represented by an explicit computational process, making this abstract theory of speech experimentally testable. In order to achieve this goal, however, abstract representation theory of linguistic forms such as words and sentences also needs to be developed further, to elucidate basic characteristics of our cognitive process of speaking and hearing as well as writing and reading. Information technology cannot make a breakthrough for the new century without deeper understanding of language and speech.
