Mouse help in the phoneme window

Use the mouse left button together with:

- the CONTROL key to add a boundary

- the CAPS key to move a boundary

- the CONTROL and CAPS keys to delete a boundary

- a double left click to add, modify or delete a phoneme.

- a double right click to add, modify or delete phoneme annotations with a dialog window. This NEW feature allows a very fast annotation as the user needs one click per phoneme. This dialog window offers two manners to annotate segments: either by means of the mouse by clicking the phoneme to be added or by entering the phoneme text with the keyboard. In the second case, characters entered by the user are filtered in order that only authorized phonetic symbols remain. Besides this basic facility, this dialog allows the user to edit existing annotations. The user

can delete an annotation with the “backspace” key provided that the editing window is empty, or move forwards or backwards with right or left arrow. By moving with arrows, the user can correct an annotation anywhere in the speech signal. In order to keep only one window for the user interaction the spectrogram window is not active during phonetic annotation. Nevertheless, the user can move in the speech signal with right and left arrow in the annotation window. The simpler way to annotate a speech file, is to insert boundaries in the whole file, and then to add phonetic symbols with this dialog window.
