Es - interactive device-independent data display
(-i item) (-a item) (-s start) (-e end) (-f item lo hi)
(-l labelname) (-12|-0) (-g spectitem) (-t) (-m) file
is a program to display portions of data sets in a file using device-independent graphics.
Mouse interaction allows selective expansion of regions of the display, and replay of speech items.
Options allow for the selection of items and the initial display of part of the timescale.
Default operation is to display all
items in file.
may also be used to add/edit annotations using the '-l' option.
and their meanings are:
Identify program and exit.
Select first item matching item specification.
Select all items matching item specification.
Select a speech item for display as a spectrogram using on-line FFT.
Control of spectrogram display. Argument is made from these letters:
'S' = display speech signal, 'W' = display wideband, 'N' = display narrowband.
This applies to all speech items displayed.
Start up with file processing tree display for item selection.
Specify a start time (in seconds) other than 0.0.
Specify an end time (in seconds) other than the length of the first speech
item in the file. If no speech item found, default timescale is 1 second.
-f "item lo hi"
Fix all displays of a given type to the y-range lo..hi.
Select labelling mode: an annotation editing facility.
The annotations to be edited must be given a name (labelname)
that is stored in the history for the annotation data set. If any
existing annotation items in the file
have the same name (i.e. with "type=<name>" in the history field),
the last is used as the initial contents of the
annotation data set.
Specify that all SP items otherwise 'unmarked' will be treated as
12-bits (-2048..2047). The marking is shown by a parameter field
entry of "bits=12" or "bits=16". Default: all unmarked items are treated as
containing 16-bit data.
Select measurement mode. Cursor position is displayed in time and frequency
in area normally used for bottom timescale.
Set "start" marker. For accurate placement, use '<' and '>' keys in
combination with mouse.
Set "stop" marker.
Replay selected segment. Appropriate speech item chosen automatically. In labelling mode, the
region to be replayed depends on the mouse location; normally the region between cursors is
replayed wherever the mouse is positioned. SY items are replayed through hardware
synthesizer or by software emulation of the SRU synthesizer (see hwsynth(3)). To move an annotation in labelling mode, click the middle button
over the annotation in the annotation edit window and then the annotation will jump to
the position indicated by the next click of the left or right buttons (or on hit of RETURN key).
To deselect, click the middle button outside the annotation edit window.
(Any button, 'q', 'x', ESCAPE) Quit program.
(Any button, 'f') Display file sub-menu.
(Any button, 'p') Play region of signal between cursors. Or 'o' plays region to left
cursor, and '[' plays region from right cursor. The speech item selected for replay is
the one under the last known mouse position - note that this means that the 'play'
button cannot be selected by the mouse!
(Left button, 'l') Scroll left. "stop" marker sets new right margin if present.
(Right button, 'r') Scroll right. "start" marker sets new left margin if present.
(Middle button, 'u') Undo previous "zoom".
('t') Go to top level of zoom.
(Any button, 'z') Zoom in to selected region. Or 'g' to goto a particular time
in the file; you are prompted to enter the time.
(Any button, 'a'. Labelling mode only) Add an
annotation at the current position of the left cursor. Type the name of the annotation
and press [RETURN]. To replace an existing annotation, position the cursor on top of it, key 'a', the
new annotation label and [RETURN]. To delete an existing annotation,
position the cursor on top of it, key 'a' and type [RETURN] only. Or 'b' to
input an annotation at the right cursor.
(Any button, 'q', 'x', 'm', ESCAPE or RETURN) Return to Main menu.
(Any button, 'h' or 'p') Print screen ("Hardcopy").
(Any button, 't') Display file history tree to reselect items for display.
(Any button, 'c') Copy displayed section of displayed items to a new file.
(Currently only some items types may be copied).
(Any button, 'l') Link displayed section of displayed items to a new file.
(Currently only some items types may be linked).
(Any button, 'q', 'x', 'o', ESCAPE, RETURN) Accept selections and return to Es display.
(Any button, 'p', 'h') Print hard copy of file history tree. Not yet implemented.
(Any button, 'a') Select all items.
(Any button, 'z') Clear selection of items.
Any speech item. Displayed as waveform with '-a' or '-i' switches, as
spectrogram with '-g' switch.
Any excitation item. Displayed as waveform.
Any period data item. Displayed at period markers.
Any fundamental frequency item. Displayed as fx trace on linear scale.
Any annotation item. Displayed as markers.
Any synthesizer control data item. Displayed in graphical form.
Fixed frame Display data in SFS format. Displayed as grey scale.
Voice/Unvoiced markers. Voicing displayed as "V" annotations.
Any coefficient data item. Displayed as spectra.
Any raw formant estimates item. Displayed as numbered points.
Any parameter track item. Displayed as trace.
Other items are merely noted in the display.
The terminal type is determined from the environment variable GTERM
if present, which is used to configure the graphics using the
information in $SFSBASE/data/digmap. If GTERM is not set, then the
TERM variable is used. The default printer is selected from the
environment variable GPRINT, which is used to configure the printed
graphics using $SFSBASE/data/digmap. If GPRINT is not set, it is
assumed to have the value 'printer'. The replay device type is
determined from the environment variable DAC, which is used to
configure the replay according to a table built in to the software
(sfsdac.c). If DAC is not set, no replay is available.
