Go back to WinPitchLTL:

  • On the toolbar select display mode:      means that you want to record a short segment (shorter or up to one screen display). The screen duration (figure 1) can be set between 1 and 10 seconds. The default duration is 2 seconds. If you want to record a longer segment  (exceeding one screen display), click on the display Mode button. It will change to As you record, you will see a continuous screen display until the end of your speech. You can record speeches for up to 12 minutes.
  • You can also determine the duration of the recording. On the toolbar select: ® Options ® Record Buffer ® Record-Duplex. A Record Set-up box opens (figure: record set-up). The recording duration by default is 300 seconds (5 minutes).
  • You are now ready to start your recording. Click      to record and     to stop. You can also use the keyboard by pressing “E” to record and “Esc” to stop.

It is also possible to record via other sources: audiotapes, CDs, sound track of video tapes, Internet sound files, etc.  Select line in in the recording properties box (figure 3).

4. To listen to parts of your recording

Specific parts of the signal can be defined with a block.

  • To define a block, click on the left mouse button (make sure the cursor has an arrow shape at that time). This defines the starting corner of the block.
  • Drag the mouse with the left button down and release it to define the opposite corner of the block (figure 6). When you release the left mouse button, the sound defined by the block will be played back.
  • To hear it again, position the cursor inside the block: the cursor shape is changed into a hand; press the left mouse  button.
  • To change the block dimensions, position the cursor near the block edges, and drag the block edge. The block can be moved without changing its dimensions by positioning the cursor inside the block and dragging the block, keeping the left mouse button down. Again, when the mouse button is released, the corresponding sound will be played back.

5. To playback items at a selected speed

You can playback the entire recording at a slower speed (to better identify phonemic or prosodic phenomena) or at a faster speed.

  • Select the Playback at a selected speed button:  . By default it is slower by 50%. To change the playback speed, select on the toolbar: Options ® Set Playback rate, enter the speed you chose and click OK. Then click again the Playback at a selected speed button. Alternatively, you can press the ‘A’ key on the keyboard to get the same result.
  • To playback selected segments of your recording at a slower or faster speed, define a block with the mouse (figure 6), position the cursor inside the block (the cursor shape is changed into a hand), press and hold the "shift" key on your keyboard at te same time you are pressing the left mouse button.

 

6. To save a sound file.

  • On the toolbar select: ® File ® Save audio file. A Save Sound File box opens (figure7).
  • In the left column, replace the * by the name you want to give to your file (up to 8 characters).
  • In the right column, determine where you want to keep this file (drive a, c, d…? directory? file? etc.)

9. To compare your production to a model production

  • Load the model production (step 7: To open a sound file). Once the model phrase is displayed on the screen, click on the Student Mode button  . When it becomes red it means that you are ready to record your own phrase.
  • Click on the record button and start recording. Your production (blue melodic curve by default) is automatically displayed above the model phrase (in white by default). Click on   to listen to your production or on  to erase your production and display the model phrase. You can repeat this operation as often as you wish. You can save your production in a specific file or in your portfolio (step 6: to save a sound file)

 

 

10. To open a new screen

  • On the toolbar select: File ® New document. A new screen opens. Click on to have a full screen and start your recording (step 2).

15. To add and place text on the screen

Text (with any font available on your computer, including phonetic fonts) can be placed, moved and edited.

  • To enter text, click on the Text button    . A text box will appear (figure 12).
  • Select the appropriate height, width, pitch and font, and enter your text. Click OK. The cursor will move with your text characters place holders.
  • To place text, press the left mouse  button. You have the option to move the text by block or by character (to align it on the curve for teaching purposes, for instance). To move a character, click on it and drag it to its new location, then release the left mouse button. (figure 13). To delete a character, select it by clicking on it, then press the keyboard delete key (‘Del’). To edit a character, double click on it. You can then change the character attributes (color, size, font). To select a group of characters, use the block function (define a block around the characters you want to edit). You can move them around, or edit them globally by pressing the keyboard’s ‘F3’ key. Furthermore, a group of selected characters can be aligned horizontally on the first character selected with the ‘L’ keyboard key.

16. To save files with text

Once you have added text to a sound file (*.wav), you can save the file as a WinPitch file (*.wpc).

  • On the toolbar select: ® File ® Save WinPitch file. A Save WinPitch File box opens.
  • In the left column, replace the * by the name you want to give to your file.

NB. WinPitch files contain all the written and graphic elements of a sound file, therefore every  *.wpc file must have the same name as its *.wav equivalent.

  • In the right column, determine where you want to keep this file (drive a, c, d…? directory? folder?).

NB.  A *.wpc file and its *.wav equivalent have to be saved in the same folder/directory (figure 14).

18. To add Bookmarks and comments via a Comments box

To enhance interactivity between students and teachers Bookmarks attached to Comments boxes can be placed anywhere along the signal to allow for easy retrieval of reference points.

  • To create and place a bookmark, click on the Dialog Box button of the toolbar  . A bookmark dialog box opens (figure 16) to allow you to specify a bookmark name, write comments, choose the color of your bookmark, etc. Create the bookmark by clicking on the Create button.
  • You can also retrieve former bookmarks by selecting their name in the list and clicking on the Find button. You can delete them the same way.
  • New bookmarks are placed by dragging the bookmark and pressing the left mouse button to position them. You can move the bookmark by selecting it and dragging it, and delete it by selecting it and pressing the keyboard delete key ‘Del’. To read the comments written in the dialog box, put the cursor on the bookmark placed along the signal. The box will open automatically. You can also put the cursor on the bookmark and press the ‘F2’ key (figure 17).
  • To modify the content of a Comments box, click twice on the bookmark and the Bookmark dialog box will open.
  • Bookmarks and their attached comments can be automatically copied and positioned anywhere along the signal using the Flag Bar buttons (figure 16).

19. To display multiple windows.

WinPitch is a Multi Document Interface program (MDI). As such, it allows you to open more than one window and to perform all the comparisons and all the sound/text editing commands independently on all the windows your computer memory would allow you to open.

  • Open a sound file (step 7) or a WinPitch file (step 17). Then open a second file the same way, but while you are selecting the name of the second file to open, press  ‘Shift’ on your keyboard. A second window will open. You can then align your two windows by using the Windows | Tile horizontally | Tile vertically | Cascade command found in the menu under Window (figure 18

 

Figure 18

 

 

 

 

20. To redesign pitch contours

For learning and correction purposes you can stylize melodic curves or redesign descending or ascending pitch contours (figure 19).

  • On the toolbar (figure 11) click on the Redesign Pitch Contour button   (or press ‘R‘ on the keyboard). The cursor becomes a horizontal white arrow with a small T above it.
  • Place the cursor on the screen where you want to start redesigning the melodic curve and press ‘B’ on the keyboard.
  • Trace the new shape with the cursor. Press ‘B’ each time you change direction.
  • Press ‘N’ to finish the track (alternatively, you can use the left mouse button and select the appropriate command on the pop up menu displayed).
  • To edit an existing melodic track, click on it to select it. The track changes aspects showing it can be edited. Move the cursor along the track: you will notice changes in the cursor shape: it takes a cross shape near the track vertices, a scissors shape along the segment, and a hand when at some distance from the track. When the cursor has a cross shape, vertices can be dragged by maintaining the left mouse button down. When the cursor has scissors shape, the segment can be cut by pressing the left mouse button, and the vertex created can be dragged to another position. To remove a vertex, select the track, position the cursor on the vertex until it becomes a cross, and click the right mouse button (or the delete key “Del” on the keyboard). The vertex will disappear and the track will change overall shape (note: end points cannot be deleted). You can select all redesigned segments with the keys ‘Ctrl A’.

22. To synthesize speech

 By repeating step 20, you can trace a new melodic contour on top of the original one and then synthesize it to listen to the new melody.

  • To synthesize speech according to signal stored and the prosodic parameters displayed on the screen, click on the synthesize button .
  • To listen to the synthesized speech again, either click on  (which starts on new synthesis process), or simply on the playback button  (or ‘Q’ key) if you are in synthesis mode. Indeed, two listening modes are available: recorded and synthesized. These modes define what buffer will be played back when the playback button is clicked.
  • To select the synthesis mode, press the ‘F’ key on the keyboard. The lower tool bar becomes yellow. To go back to recorded mode, press again the ‘F’ key. The toolbar regains its gray color. In recorded mode, all readouts pertain to the prosodic parameters of the recorded signal; in synthesis mode, all readings pertain to the prosodic values, whether copied (by default) or user defined, of the synthesized speech. This is also true for defined blocks (step 4) where recorded and synthesis modes can be toggled using the ‘F’ key on the keyboard to quickly compare recorded (i.e. original) and synthesized speech.

 

 

23. To redefine the duration of speech segments

As for pitch, duration is another prosodic parameter that the program allows you to modify for learning and corrective purposes. Duration changes are displayed in %, and are negative (i.e. speech slower) when the curve is below the zero line of the signal (yellow curve near the bottom of the screen), and positive (speech faster) when positioned above that zero line (figure 21).

  • On the toolbar (figure 20) click on the Redefinition of duration button  (or press ‘R‘ on the keyboard). The cursor becomes a horizontal white arrow with a small T above it. Then follow the same procedures as in step 20 although this time you are working on the signal to modify duration of speech segments.
  • You can then repeat step 22 to synthesize and hear the result.

 

Figure 21

 

 

24. To save a synthesis file

  • On the toolbar select: ® File ® Save Synthesis file. A Save Sound File box opens (figure7).
  • Repeat the procedures of step 6.
  • Synthesis files are *.wav files, but you can add text, bookmarks, comments on the synthesis file, the same way you do for a recorded sound file. You can then repeat step 16 to save the file as a *.wpc file.


 

Level 4: Professor

 

 

25. To select level “professor”

  • Click on the toolbar: Options ® Select Version ® Professor ® OK

The program displays a toolbar with new functions of WinPitchLTL (figure 22)

 

 

Figure 22

 

 

 

 

26. To load a document

  • On the toolbar click on the Load a Document button   . When the Load File box opens (figure 15), search for your file in the right column, choose if you want to open a *.wav file or a *.wpc file at the bottom left corner of the Load File box, select the specific file in the left column and open it.

 

 

27. To cut, copy and/or paste a sound block

In the same way we can cut/copy/paste parts of text in a word processor program, WinPitchLTL has sound Cut ,Copy    and Paste  capability, activated when a block is defined  (step 4). Cut will copy the sound block to a buffer and play back the resulting recorded sound. Paste will paste the cut or copy sound block into the current recorded sound and play it back. The undo button   will cancel the last operation. (This button will undo the last action for prosodic track placement and editing as well).
