I would like to add an item to Praat's dynamic menu, and use an
environment variable to specify the directory in which the item's
script resides. Is this possible, or could it be made so? This would
be helpful to our group, and to people to whom we deliver our scripts.

For example, say I have a bunch of scripts in the directory
C:\Scripts, and an environment variable SCRIPT_DIR set to
"C:\Scripts". I would like to be able to specify a script path like
'environment$("SCRIPT_DIR")'\myscript.praat in the "Add to dynamic
menu" dialog instead of C:\Scripts\myscript.praat. This would allow
people to put their scripts in whatever directory they like, but use
the same buttons.ini file.

Thanks,

     Harold Mills

I'd be grateful for anyone's tips on how to incorporate into a script a command
to regularly save the object being worked on.  I am using a TextGrid to
annotate velar stop duration, and have scripted the process such that when I
save through the script, Praat writes to TextGrid, then reads the TextGrid and
outputs the results to a .txt logfile.  (This is as opposed to saving the
TextGrid outside the script and directly through the operating system, in the
same way as you would save any other file;  in that case, of course, the
TextGrid is saved but the script commands to read and output are not followed.)
  I would like to script Praat:

- to save regularly for me
- after each save, to overwrite the logfile for that particular TextGrid with
the new data, as opposed to adding all the data again from the line after the
previous entry.

I've searched the group archives for likely terms, but not found any threads
that answer these questions.  If it would be helpful for me to just attach my
script, please say so;  this is my first post to the user group!

you may be looking for the variable defaultDirectory$ (see Scripting 5.1 for
this variable and four other directory variables), although then again, I see
that you may want to use it *outside* the script.

The nested expansion that you propose (like the backquote mechanism in some
shell languages) does not exist in Praat. However, if your menu command addition
is done in a script itself, one can do:

    scriptDirectory$ = environment$ ("SCRIPT_DIR")
    Add action command... 'scriptDirectory$'/xx.praat ...

That said, I don't understand very well what you are trying to achieve. You say
you are delivering scripts to other people, but also talk of installing these
scripts by adding them to menus via a dialog in the script editor (rather than
via a separate installation script, such as in plugins). But if these people
install the scripts themselves via such a dialog, why would they need the
environment variable? They could just specify the directory of their choice.

Hello, I just started working on my dissertation using PRAAT. The
problem I have is that I cannot open one table for pitch analysis with
average, maximum and minimum measurements and I have to press "get
pitch" and then "maximum" and "minimum" every time. I managed to get
the table once, but it happened randomly. Which is the right procedure
so as to get the measurements all together?
  Also, I cannot open my saved files from desktop because an error
occurs and I always have to open PRAAT and then the files. Isn't there
any shorter way to see my files? i do not understand why I cannot open
them from desktop. Thank you very much. Panagiota Gkolemi

Thank you to Jonas Lindh and Paul Boersma for their replies to my query
about dynamic menus. I'm sorry my message wasn't clearer. We have a bunch of
scripts to distribute both within our group and to others, and as part of
the installation process we want to add some buttons into the dynamic menu
in some automatic but flexible fashion. We did not know about the plug-in
facility, which sounds like it's just what we need.

Thanks,

     Harold Mills

I need to output pitch and intensity values of speech files in XML.
To do this, I create pitch and intensity objects and then iterate over
the number of values, get the pitch and intensity value and write them
to file.
In script language (without xml markup):

=== begin script ===
Read from file... blah.wav
To Intensity... 100 0.01
select Sound blah
To Pitch (ac)... 0.01 75 15 no 0.03 0.45 0.01 0.35 0.14 600

select Intensity blah
nrsamples = Get number of frames
fileappend 'output$' 'nrsamples' 'newline$'
for samplenr from 0 to nrsamples
   select Intensity blah
   intensityvalue = Get value in frame... samplenr
   select Pitch blah
   pitchvalue = Get value in frame... samplenr Hertz
   fileappend 'output$' 'intensityvalue' ,  'pitchvalue' 'newline$'
endfor
=== end script ===

This works fine, but is terribly slow. Is there a faster way to get
the individual sample points? Or a smarter way to get XML output?
(Reformatting the praat output afterwards is not an option)

The following is faster. By looking into the Intensity object it does not have
to do the back-and-forth selection, and it writes to the file just once:

select Pitch blah
nrsamples = Get number of frames
text$ = "'nrsamples' 'newline$'"
for samplenr from 1 to nrsamples
    intensityvalue = Intensity_blah [samplenr]
    pitchvalue = Get value in frame... samplenr Hertz
    text$ = text$ + "'intensityvalue' ,  'pitchvalue' 'newline$'"
endfor
text$ >> 'output$'

Hello,
Could pleae anybody remind me of how to pass a numeric and/or string
argument as variable to a script. I would like to do something like:

<execute myscript.praat 'filename$' 'path$' 'z'>

Sorry, I have the impression that this is already a FAQ, but I don't
find the post.

Many thanks in advance,

It is not a FAQ, because the answer is in the manual. The above is
about right, but if your variables can contain spaces, you should
enclose all but the last in double quotes:

execute myscript.praat "'filename$'" "'path$'" 'z'

I'm setting up a perception experiment in Praat and I'm wondering if it is
possible to have
some practice stimuli before the experiment starts properly. I can't see how I
could write that
into the ExperimentMFC file. Does anyone know if this is possible?
Thanks,
Ruth.

There are basically two ways. One is to create a small additional
experiment and run that first; this would be appropriate if you don't
want to reveal your target stimuli to the participant before the
experiment starts. The other way is to simply start your experiment
until you are satisfied that the participant understands the task and
the sound intensity is right; you can then stop the experiment by
clicking the close button and Run again; there will be a new
randomization when the real experiment starts.

I have made a script that finds onsets from the slope of the energy
curve of the signal, and writes onset times to a text grid. I would
like to hear the extracted onset times as clicks, to test whether they
sound accurate or not: is there an easy way to do this in Praat?

I've also run into this ?bug? recently. It seems that whenever
replace_regex$() is used to replace something other than a literal
string (i.e. anything with regex voodoo in it) with nothing, the empty
string is returned.

A workaround is to replace what you want to have deleted with a dummy
string you know will not interfere (i.e. cause false positives) and
wrap the replace_regex$() function in a normal replace$() to delete
all instances of the dummy string.

For example, while:

replace_regex$("foo bar baz", " ba[rz]", "", 0)

erroneously returns the empty string,

replace$(replace_regex$("foo bar baz", " ba[rz]", "%", 0), "%", "", 0)

works as expected, returning "foo".

Dear Andy,

one simple approach I could suggest is to turn the TextGrid tier into
a PointProcess (or simply create a PointProcess in the first place),
then synthesize it as a pulse train. E.g.

# Assuming you have your onset times on tier 1:
Extract tier... 1
Down to TableOfReal (any)
To Matrix
Transpose
To PointProcess
To Sound (pulse train)... 44100 1 0.05 2000

(This is slightly more awkward than converting directly from tier to
PointProcess, but should work regardless of labels or tier type.)

Although I'm not sure whether the resulting pulses sound like you want
your clicks to sound...

Best wishes,

Hi,
I'm a new praat user, and have a couple of questions that I couldn't find
answers to in posts.

First, the data I'm using is a radio programme recorded into Praat from BBC
'listen again'
using Soundflower. Will there be any corruption of pitch data resulting from
this process? Or
any settings I should be aware of to optimize the data?

Second, my interest is pitch in interactions, rather than specifically in
production or
reception. As I understand it, in the pitch settings, the "voice" option is
optimized to reflect
vocal chords, and "intonation" for perception. Should I just choose one, or is
there a way to
optimize the readings?

Many thanks,

Alex.

Hi all,

I'm currently using Ltas to create power spectra for sounds we used in
the project.

Basically, we have sounds grouping into music, human voice and white
noise etc. I plan to create average power spectra graph for each sound
groups for comparing acoustic properties.

For each group of sounds (~50 samples)
Use Ltas with bins of 10 Hz for each sound, and then take "average"
over all of them to obtain the mean values for that sound group for
graph plotting.

However, there are a lot of negative values (in dB/Hz Pa, Ltas default
setting) at frequencies higher than 11 kHz. Am I doing the right things?
I thought they should be all positives as values indicating energy
levels across each frequency bins.

I'd like to know if I doing somethings wrong, using wrong parameters
or else.

Thanks a lot

Damon

Dear Damon.
dB is not is related to the smallest hearing level in Pa 0,00002 and therefore
some frequencies will have negative values as 0 is only related to this hearing
threshold.
Best regards
Jonas

We are three Linguistics' students from Barcelona. We have just
started using Praat for a speech analisys subject. We need to
calculate the values of the first and second formants of the vowels in
a recorded speech in catalan. We have been considering the option of
extracting this values with a script after labeling the file with a
TextGrid. We found on the Internet one that extracts the values of the
F0 and whe don't know how to manipulate it to make it extract the F1
and F2 values.

We've been reading the help files, but we're only beginners and we
would appreciate all the help you could give us.

Thanks a million!

I have uploaded a script called "analyse intervals.praat" to the
files section of this site

	 http://uk.groups.yahoo.com/group/praat-users/files/Daniel%20Hirst/

   you can place the script in a folder containing two other folders -
one containing sounds and the other containing textgrids

If you then run the script it will calculate various F0, intensity
and formant values for the first and second half of each labelled
interval in the tier which you specify when you run the script.

It will skip intervals labelled "#" or "_" or with no labels.
The output will go to the info window which you can then save to a
text file. The output format can be directly read into a statistics
program such as R. (see my following message)

let me know if you have any problems - it should be very easy to
adapt this script to what you are trying to do.

Harald Baayen, formerly at Max Planck Institute and now at the
University of Alberta, Edmonton, has written an excellent
introduction to statistics for linguists which I highly recommend
entitled:

	 Analyzing Linguistic Data. A Practical Introduction to Statistics
using R

It is aimed specifically at linguists with little or no mathematical
background and provides a hands on approach to statistics using the
very powerful (and free!) multiplatform statistics package from the R
project. He provides detailed instructions in the introduction how to
download and install the program.

The book is shortly to be published by Cambridge University Press but
in the meantime it can be downloaded as a pdf file from the following
link.

	 www.mpi.nl/world/persons/private/baayen/publications/baayenCUPstats.pdf

The initiative of making the book freely available prior to
publication is to be strongly encouraged and I hope many of you will
not only download your own free copy but will also encourage your
library to buy a hard copy of the book.

I'm piloting an experiment at the moment having written several Experiment MFC
files. I have
the same experiment for English, French and German listeners. The rectangle in
which they
click with their response contains an "a-umlaut" character in German, and an
"e-acute"
accent charcter in French. I have tried typing these into the script using the
commands I
found in the Praat manual, but they don't work as it tries to read them as part
of the "" marks
surrounding the text to be displayed.
Does anyone have any ideas on how I might get these characters to appear
properly on
screen?
Thanks, Ruth.
