    Remus - 2011-01-28

    Hello everyone,

    I am using Sphinx3Align because I need a phone segmentation of my input data.
    For exemple, I need for a 'hello' to have h e l l o indicated in time
    intervals.

    This worked for now and I obtain files like phseg or lab.
    Problem is Sphinx is poorly documented. So, I would have 2 questions :

    1. phseg files

    I have an output like

    SFrm EFrm SegAScr Phone
    0 3 -8237 SIL
    4 16 -18026 SIL
    17 22 -21172 n SIL aeA b
    23 26 -13050 aeA n m e

    Is it normal to have multiple suggestions for some phonems? I noticed the
    first one is also the good one.

    1. .lab files

    What is this xlab format? Here is an example:

    0.030000 125 SIL
    0.160000 125 SIL
    0.220000 125 n

    The first value seems the end period for a phoneme. But what 125 represents?
    Also, I have noticed the chosen phoneme is the good one.

    Also, if some of you kno where I can generally find help about parameters and
    so on, please tell me. Sphinx seems rather undocumented.

    Thank you

    Is it normal to have multiple suggestions for some phonems? I noticed the
    first one is also the good one.

    They are not multiple suggestions but a context used to match this segment. If
    you use context-dependent senone model for alignment (it's better to use
    context-independent one) it will output the context in the following format

    central phone, left phone, right phone, senone type (b = begin, s = single, i
    = middle, e = end)

    1. .lab files What is this xlab format? Here is an example: 0.030000 125 SIL
      0.160000 125 SIL 0.220000 125 n The first value seems the end period for a
      phoneme. But what 125 represents?

    125 tells that it's phone label. In xlab there can be labels of multiple types
    - word labels, phone labels, intonation labels. 125 encodes phone label. You
    can ignore it if you don't need it

    Also, if some of you kno where I can generally find help about parameters
    and so on, please tell me.

    Extensive documentation is available on the wiki, in forum archive and in
    sources. You probably want read more. If you have some specific queries you
    are welcome to ask. We are also grateful for documentation improvement
    contributions.
