FIND_PHONE(1S)

NAME
find_phone - searches the contextual data bases for a specified phoneme, in context of other required phonemes.

SYNOPSIS
findphone [options] {dbname} {search pattern}

DESCRIPTION
find_phone searches the contextual database created from the listing of lola and waveform files. {dbname} indicates the basename of the database to use for the search procedure, and must match the basename used when creating the database. The {search pattern} is used to describe the set of phoneme searches to perform. The search pattern must conform to the following format: {pre context list}, {main phoneme list}, {post context list} with phonemes in each list separated with spaces. Thus for examples to search for all examples of "iy" and "ah" with pre contextual phoneme either "s" or "t" and post contextual phoneme either "th" or "g", the search pattern will be: s t,iy ah,th g

OPTIONS

-f [log filename] Sets the search log file name
    [dbname.log]

-l [lola filename] Sets the lola output file name
    [dbname.lola]

-w [waveform filename] Sets the waveform output file
    [dbname.wav]

-s [spectrogram filename] Sets the spectrogram filename
    [dbname.dft]

-W Create waveform file
    [Do Not Create]

-S Create Spectrogram file
    [Do Not Create]

-c [number] Saves the number of phonemes found
    [Save all]

-p [number] Sets the pause in milliseconds between phonemes
    [60]

-t Saves the phoneme occuring after target phoneme
    [don't save]

-e Saves the phoneme occuring before target phoneme
    [don't save]

-q [number] Counter number of phonemes before saving
    [0]

-h Help

OUTPUT
The output of the search process depend mostly on the options given. With all required options set find_phone generates the following files

{dbname.lola}
    The lola label file which matches the search criterion

{dbname.wav}
    The waveform file containing the extracted speech data

{dbname.dft}
    The corresponding spectrogram for the extracted speech

{dbname.log}
    A log file containing information for future merging

EXAMPLES
The following example will search for all occurrences of "ah" in context of "t" and "s" find_phone -t -e -S -W english "t,ah,s"
