# Cluster Speech

The following schema describes how to segment an audio file into speaker clusters labelled `Cluster_0`, `Cluster_1,` and so on.

    [clusterSpeech]
    0 = a <- wav3(MONO, input)
    1 = w1 <- audiopreproc3(A, a)
    2 = f <- frontend3(_, a)
    3 = nf <- normalizer3(_, f, w1)
    4 = w2 <- segment3(_, nf)
    5 = w3 <- splitspeech3(_, ws:w2, wc:w1, nf)
    6 = output <- wout3(_, w3)

`0` | The `wav` module processes wav audio data.
`1` | The `audiopreproc` module processes the audio `(a)` into Music, Speech, or Silence
`2` | The `frontend` module converts audio data `(a)` into speech front-end frame data.
`3` | The `normalizer` module normalizes frame data from 2 `(f)`.
`4` | The `segment` module finds short homogeneous acoustic segments.
`5` | The `splitspeech` modules forms these into speaker clusters.
`6` | The `wout` module writes the audio speaker clusters.
