9. Summary
</SectionTitle>
    <Paragraph position="0"> We have described a novel method for speaker independent recognition of fluent speech from a large vocabulary. The system is a clear and simple implementation of well known linguistic theories of speech perception. The two most striking features of the system are that phonetic decoding is accomplished by a simple optimal search algorithm operating on a stochastic model of the acoustic-to-phonetic mapping and that, after phonetic transcription, processing is entirely symbolic and makes no reference to the acoustic signal.</Paragraph>
    <Paragraph position="1"> The performance obtained is not competitive with those obtained from traditional techniques but offers several advantages deriving from the fact that phonetic transcription is independent of lexical or syntactic considerations.</Paragraph>
    <Paragraph position="2"> The method described here is in its very earliest stage of development. We are optimistic that further experimentation will soon yield performance at least as good as that displayed by conventional methods.</Paragraph>
