HTK-HLEd

HLEd之用法

  The progeam is a simple editor for manupulating label files. Typical examples of its use might be to merge a sepquence of labels into a context sensitive set.
  HLEd works by reading in a list of editing commands from an edit script file and then makes an edited copy of one or more labels.The commends supported may be divided into two sets.Those in the first set are used to edit individual labels and they are as follows


For Example

EX
IS sil sil
DE sp

EX: Expand all labels either from words to phones using the first pronunciation from a dictionary when it is specified on the command line otherwise expand labels of the form which include a complete orthography for a sub-word based recogniser. When a label is wxpanded in this way the label duration is divided into enqual length segments

EX命令表示按照字典查询

IS A B  Insert label  A at the start of every transcription and B in the end

IS表示在每个话语前后插入sil

DE sp:delete any occuurrences pf lavels A or B etc.

DE:phones.mlf中的单词不用sp分开

$HLEd -A -D -T 1 -l '*' -d dict -i phones1.mlf mkphones1.led words.mlf

-d f:Read a dictionary from file s and use this for expanding labels when the EX command is used.

-i mlf:This specifies that the output transcriptions are written to the master label file mlf

作用： 把words.mlf里的孤立单词分解为单个音标
       dict里是词典，用来查询作用
       mkphones1.led里是所用到的单音节
