Transcription Script

The 'Transcription' script is a tool in STx specifically written for transcribing signals. You will find it in the bottom left-hand corner of the Workspace where it is called Transcription.

When starting the Transcription script, you must select the sound file in the Workspace you wish to transcribe. This is unlike the analysis profiles, which analyse a segment. The following dialog will then appear.

Here you have the choice to choose which 'view' you would like.

wave overview & spg. section

A waveform overview of the whole sound file and a spectrogram graph of a section of the sound file.

wave only

Displays a waveform plot of a section of the sound file, with the possibility to 'scroll' through the sound file. The length of the displayed signal is defined the the 'scrollbar Length'.

wave & spg. section

Displays both a waveform and a spectrogram plot of a section of the selected sound file. As with the 'wave only' view, the section length is defined by the 'scrollbar Length'.

Views

wave overview & spg. section

This view displays a waveform of the whole file and a spectrogram of a section of that file. This means that you can see all the segments in the file in the waveform graph. Navigating around the file in the waveform, you can then view a section of it as a spectrogram (e.g. with the hotkey 'S').

wave only

The wave only view displays a section of the signal as a wave form. The length of signal displayed is specified by the Length value in the start-up dialog. You can then scroll through the sound file using, for example, the hotkeys 'M' (forwards) and 'N' (backwards).

wave & spg. section

This view also only displays a section of the sound file. The waveform and spectrogram are time-aligned.

F0 / Formant Extraction

You can display the F0 and formants in the spectrogram by pressing the button. The settings for extraction are in the F0 / Formant Extraction Settings dialog reached by pressing the 'f0/for' button .

Settings

There are many aspects of SPExL that you can change via the Settings dialog reached by the 'main' button, or the 'settings->setup dialog' context menu.

SPExL Hotkeys

Note that unless otherwise specified (e.g. with 'Shift'), all hotkeys are lowercase.

Analyze Hotkeys

Ctrl+N	Select a viewer and profile to analyze the signal between the cursors with (opens new window).
Ctrl+A	Analyze the signal between the cursors with the viewer/profile which was used last.

Cursor Hotkeys

Key	Description	W. Overview & Spg. Section	Wave only	W.&S. Section
B	Move the cursors to the selected segment.	X	X	X
D	Move left cursor to the left.
F	Move left cursor to the right.
E	Move left cursor to the left in large steps.
R	Move left cursor to the right in large steps.
J	Move right cursor to the left.
K	Move right cursor to the right.
U	Move right cursor to left in large steps.
I	Move right cursor to right in large steps.
L	Flip left cursor around right cursor.
Shift + L	Flip right cursor around left cursor.

Playback Hotkeys

Escape	Stops playback
Space	Play between the cursors
A	Play all of signal in waveform window
O	Play all of the signal from the right-hand cursor to end of waveform window
P	Play the selected segment
W	Play all of signal up to the left-hand cursor

Scrollbar Hotkeys

The length scrolled is defined when SPExL starts up (Scrollbar Step (%)).

Ctrl + G	Jump top a position specified in seconds
M	Scroll forward
N	Scroll backwards

Segment Hotkeys

Shift + B	Move the selected segment to the cursor positions.
Enter	Create new segment between the cursors.

Segment List Hotkeys

Ctrl + R	Open the segment list sort order dialog.
Ctrl + Numpad Plus	Resize all columns to fit their content

Spectrogram Hotkeys

Shift + Add	Increase amplitude floor.
Shift + Subtract	Decrease amplitude floor.

Zoom Hotkeys

Y	Zoom in on the x axis around the mid point between the cursors.
Q	Zoom out on the x axis around the mid point between the cursors.
Ctrl + Add	Zoom in on the y axis around the active cursor
Ctrl + Subtract	Zoom out on the y axis around the active cursor
V	Zoom between cursors on the x axis
Shift + V	Zoom between cursors on the y axis. Note that this only works if the cursor style allows y axis positioning.
G	Zoom in around the left-hand cursor.
T	Zoom out around the left-hand cursor.
H	Zoom in around the right-hand cursor.
Z	Zoom out around the right-hand cursor.
X	Reset the zoom

Misc Hotkeys

Key	Description	W. Overview & Spg. Section	Wave only	W.&S. Section
S	Redraw the spectragraph graph showing the signal between the cursors in the waveform graph.	X
