Overview of Main page

TEVA is used by clicking buttons on the current page. Here is a list of the buttons on the Main page with a description of their use. English labels will be used here. The keyboard shortcuts are given between the []-brackets (might depend on language). See also the Overview of Configuration page.

The display

In the center of the page is the display area where a graph is drawn with the analysis. Below the time axis (if present), the voiced parts are indicated with blue-gray line segments. A green marker will indicate the point where the Harmonicity is maximal (which indicates a potential "best" part). These two additional markers will in general appear only after, respectively, the Pitch and Harmonicity contours have been displayed.

General functions

Quit: [Q] Stop TEVA. Will save the current preferences
Settings: [S] Go to Configuration page
Refresh: [h] Redraw the current page, hitting the space-bar always refreshes the screen
Help: [?] Press on the button you want information on, press Help again to continue

Recorded speech

Speaker: [k] Input speaker data. Speakers from a table can be selected by ID, row number, or by stepping to the next, >, or previous , <, speaker. Click Ready to complete
Nxt: [x|] Alternative to Speaker button in Serial mode, steps through a list of recordings one by one
Open: [O] Open sound file (or a list of sound files)
Record: [R] Record your speech. You have 4 seconds, watch the recording "light" on the top left
Play: [P] Play back of recording

The sound level of the sound will be indicated as a colored circle in the top left of the page. The diameter scales with the maximal amplitude and the color indicates whether the maximal amplitude is too high (red), good (green), or too low (darker green to black).

Selecting an interval of speech

The current time window will be indicated with vertical blue lines if it is smaller than the current display. Changing the display (eg, zoom in or out) will set the display window to the current time window.

Select: [e] Select a new start and an endtime with the cursor
To selection: [c] Go to selected start and endtime
Zoom out: [u-] Double the current time window
Zoom in: [n+] Halve the current time window
Previous: [<] Previous interval, or shift current time window to the left
Next: [>] Next interval, or shift the current time window to the right

A shortcut to the Select button is to click inside the display graph. The point where clicked will be marked as the first boundary and all will proceed as if the Select button was pressed. After selecting the first boundary, pressing the - or + keys will position a 1 or 2 second window around the (first) selection point, respectively. Pressing any other key or clicking the Select button again will cancel the selection.

Saving and printing a report

Print [#] Save recording and a report of the analysis in printer format

The current sound, and a report with all graphs and the analysis results can be saved into a seperate map (or directory). The analysis windows are calculated and pictures are stored. A web page (.html and .odt) is created for printing on Apple OSX and Microsoft Windows systems. On Apple OSX the pictures are saved as PDF graphics, on Microsoft Windows as WMF graphics. On these two systems, a web page (.html) is created with the report. On all systems, pictures are also saved as PostScript graphics (EPS) and a report with an .odt extension is created. This report can be opened with OpenOffice.org or LibreOffice word processors for inspection and printing. Both OpenOffice.org and LibreOffice.org are Free and Open Source word processing programs.

Analysis calculations and displays

Selected statistics about the analysis will be written below the display. This includes the Acoustic Signal Typing analysis related to the display.
