Eswin -- SFS/Windows general display program


Eswin (-I) (-i item) (-a type) (-g item) (-n item) (-G[SWN]) (-f item lo hi) (-l labeltype) (-s start-time) (-e end-time) file


Eswin is a program to display portions of multiple data sets from a single file. The display can be zoomed and scrolled. Speech items, Lx items and synthesizer control data can be replayed. 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 over the duration of the longest. Eswin may also be used to add/edit annotations using the '-l' option.


-I Identify program and exit.

-i item Select first item matching item specification.

-a type Select all items matching item specification.

-g spitem Select a speech item for display as a spectrogram using on-line FFT.

-G opt 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.

-s start Specify a start time (in seconds) other than 0.0.

-e end 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.

-l labelname 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.



Set "start" marker.


(In main area). Set "stop" marker. (In left hand axis boxes) Display context menu.


Space Play speech between cursors. To select which speech item, click in the left margin of the required item.

Tab Select next speech or Lx item for replay.

L Scroll left. "stop" marker sets new right margin if present.

R Scroll right. "start" marker sets new left margin if present.

U Zoom Out. Undo previous "zoom".

T Goto Top. Go to top level of zoom.

Z Zoom in to region between cursors.

A (annotation 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, and press [DELETE].

B (annotation mode only). Add an annotation at the right cursor.


1.xx Any speech item. Displayed as waveform with '-a' or '-i' switches, as spectrogram with '-g' switch.

2.xx Any excitation item. Displayed as waveform.

3.xx Any period data item. Displayed at period markers.

4.xx Any fundamental frequency item. Displayed as fx trace on linear scale.

5.xx Any annotation item. Displayed as markers.

7.xx Any synthesizer control data item. Displayed in graphical form.

Any word chart. Displayed with vertical axis as score. Only the best scoring words that fit on the screen are displayed.

9.xx Fixed frame Display data in SFS format. Displayed as grey scale.

10.xx Voice/Unvoiced markers. Voicing displayed as "V" annotations.

11.xx Any coefficient data item. Displayed as spectra.

12.xx Any raw formant estimates item. Displayed as numbered points.

16.xx Any parameter track item. Displayed as trace.

Other items are merely noted in the display.


5 Edited annotations.
