# 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.

    [WavToFmd]
    0 = a ← wav(MONO, input)
    1 = f ← frontend(_, a)
    2 = nf ← normalizer(_, f)
    3 = output ← phraseprematch(WRITE, nf)

`0` | The `wav` 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 normalized frame data from `2` (`nf`) is written to an .fmd file for phonetic phrase search.
