# Preprocess Audio Files for Phonetic Phrase Search

The following schema describes the preprocessing of an audio file to create a phoneme time track file required for phonetic phrase search.

    [createFmd]
    0 = a, ts <- audio(MONO, input)
    1 = f <- frontend(_, a)
    2 = nf <- normalizer(_, f)
    3 = output <- phraseprematch(WRITE, nf, ts)

`0` | The `audio` module processes the mono audio.
`1` | The `frontend` module converts the audio data into speech front-end frame data.
`2` | The `normalizer` module normalizes the frame data from `1` (`f`).
`3` | The `phraseprematch` module processes the normalized frame data from `2` (`nf`) to generate phone-track information, which is written to the .fmd file for phonetic phrase search.
