<ul>
  This is the verifier utility, core component of the speaker verification
system.
</ul>

<a name="options">
<b>options:</b>
<br><br>

<ul>
  <li> -help: displays a help message
  <li> -algo_type: the varification algorithm (default=hmm)
  <li> -mode: the implementation mode
  <li> -param: set the parameter file for the verifier
  <li> -pos_example: positive example list file when doing svm/rvm training
  <li> -neg_example: negative example list file when doing svm/rvm training
  <li> -model_file: statistical model file(svm/rvm test)
  <li> -audio_db_file: audio database(identifier feature file mapping, svm/rvm test)
  <li> -output_file: contains verification results (svm/rvm test)
  <li> -decision_thresholds: the thresholds based on which a verification decision is made (default = \"-100.0,0.0\")
  <li> -list: an input list of utterance identifiers
  <li> -verbosity: log verbosity level
       <ul>
	 <li> NONE: output the number of files processed 
	 <li> BRIEF: output also names of the files processed
	 <li> DETAILED: output also hypotheses, scores and frames number 
       </ul>
       <br>
  <li> -debug_level: debugging information level (default NONE)
<ul>
	 <li> FILE: output hypotheses to single output file, specified by "-output_file" option
	 <li> LIST: output hypotheses to files, output file list is
specified by "-output_list" option
	 <li> TRANSFORM: output hypotheses to the existing directory specified by "-directory" while preserving N directories of the input file names (N is specified by "-preserve" option)
       </ul>
       <br>
  <li> -log_file: log file used instead of stdout
</ul>       

<a name="examples">
<b>examples:</b>
<br><br>

<ul>
  <li> This example shows how to verify utterances specified in the input list "id_list.sof", while output options are specified in the parameter file "param.sof":

<pre>
isip_verify -par <a href="/perl/ifc_document.pl?file=$isip/util/speech/isip_verify/param.sof">param.sof</a> -list <a href="/perl/ifc_document.pl?file=$isip/util/speech/isip_verify/id_list.sof">id_list.sof</a></pre>

  <li> This example shows how to train input utterances specified in the positive and negative example list using svm algorithm:

<pre>
isip_verify -algo_type svm -mode train -par param.sof -pos_example pos_examples_list -neg_example neg_examples_list</pre>
