[Index | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11]

Preparation: Use the sound file snd4wsman10.wav for your practice. Open the file with the Transcription configuration.

  1. Click the transcription pane
  2. Move the cursor at the point you want to label and type the label. For example, to label [s], select the starting point of [s], move the cursor to the selected point and type 'w' (since this is the word initial). Then, select the end point of [s]. Move the cursor to the end point of [s] and type 's'.
  3. When the label doesn't lined up with the target point, you can move the label by dragging the label.
  4. If you want to delete the label, right-click on the lable while pressing the Shift key. Select "Delete Label" from the options.
  5. To save the transcription, right-click to select 'Save Transcription As'. Select the location to save the label file and click 'Save'. The file will be saved as a text file, but the extension for a label file is *.lab. In this example, stored filename is 'snd4wsman10.lab'. Stored file looks like this:

    0.0000000 0.0762946 w
    0.0762946 0.1645570 s

    1st column: Time at the previous label (e.g. 0.0762946)
    2nd column: Time point at the label (e.g. 0.1645570)
    3rd column: Label (e.g. s)

    In this example, total duration of [s] is also calculated by column2 - column1. See the data saving in the next page.
