no, this cannot be done. Specially for long sound files, we have the 
option "Open long sound file...", so that you would never have to 
perform the very error-prone sequence of dividing sounds up and 
putting them back again.

Re: Praat Skript: Duration of pauses

At 11:55 +0000 31/1/10, Michelle Porter wrote:
>you missed out the plural s!

some other problems in the script are:

>>  name$ = selected$("TextGrid w1_alt_Phon")

should just be

    name$ = selected$ ("TextGrid")

>>  printline 'tab$'number 'tab$'label 'tab$'duration

this creates column names that contain a space at the end, which is 
probably not what you want. There's also an extra tab after the last 
column. You should fix that if you want to read the contents of the 
Info window into a Table.

>>  Additionally, I would like a command which creates this table in a

to store the contents of the Info window in a file, you do

    filedelete yourFileName.txt
    fappendinfo yourFileName.txt
    Read Table from tab-separated file... yourFileName.txt

this also reads it into a Table.

Normalisation LTAS

Hello,

I would like to normalize the values in a LTAS-object,
in order to compare LTAS from different
speakers. Is there any way to do this in Praat? I have never done a normalisation before so some helpful hints
would be great!
Thanks in advance!

Greets, Susann

Unvoiced intensity showing 'undefined'...

Hi, 

I have the following script which takes in a folder of sound files, creates VUV textgrids and prints average
Voiced and Unvoiced intensities:

clearinfo
# set parameters
vuvTier = 1
sumOfDbValuesV = 0.0
sumOfDbValuesUV = 0.0
numberOfV = 0
numberOfUV = 0
numberOfS = 0
vuvTier = 1 
voiced_totaldB = 0
unvoiced_totaldB = 0

directory$ = "C:\Documents and Settings\SXP231\Desktop\test"

filelist = Create Strings as file list... list 'directory$'/*.wav
numberOfFiles = Get number of strings

for ifile to numberOfFiles
select Strings list
fileName$ = Get string... ifile
sound = Read from file... 'directory$'/'fileName$'
intensity = To Intensity... 80 0 yes

# re-initialise totals
unvoiced_total = 0

LTAS : Find right measurement

Hello Praat-Users,

I am new to Praat and I need some urgent help with choosing and operating the right Queries for an LTAS object.
I would like to compare the LTAS object of one person recorded two different times, one expecting a lower
loudness and the other a higher loudness (lower vocal effort/higher vocal effort)
What queries would be best to analyse and compare these two LTAS objects? 

With "Get slope" I can get the spectral tilt of the LTAS object chosen. A lower value would indicate a
hyperfunctional voice and a higher a hypofunctional voice. Is there anything else I can say about the
given values showing spectral distribution? Must I choose db, sone or energy? What would be best for comparing?

I would like to show that one LTAS object is spoken with higher vocal effort. So there must be more high
frequency energy in the long term spectrum. Which "Query" is best to illustrate this fact?
My ideas: "Get frequency..." and then choose any high frequency value (f.ex. 3.4 kHz) which should have a
higher value compared to the one which has a lower vocal effort? 

The bin width is 125Hz and the frequency range 0-6000 Hz

How can I get a spectrum that clearly shows the peaks in this range? Then a list of these peaks with the energy
distribution would be great so that I can compare the lists of two LTAS objects. For example show that the
one with lower vocal effort has lower energy values in the higher frequencies.

How can the relation to loudness be shown and measured in the best way? 
Is it possible to get information about the fundamental frequency from the LTAS object?

I hope you have some ideas about these points...Thank you very much!

Greets,
Ellen

no, only the *mean* intensity over all those intervals comes out as 
"undefined". This is because one of the intensity measurements is 
undefined, namely the one at the very beginning or end of the sound. 
Apparently the first or last interval falls entirely inside the white 
areas at the edges.

>The only way the script will get an UV intensity if is I set the

yes, this makes the white areas smaller.

>Can anyone help as to why there are some discrepencies between my

There are no discrepancies. You will get "undefined" if you do "Get 
intensity" in the sound window either for the first or for the last 
interval.

Here is how you repair your script (I corrected several more 
mistakes, such as unmatching endifs, unmatched endfors, wrong 
location of zeroing):

clearinfo
# set parameters
vuvTier = 1
numberOfS = 0

though you don't say *what* didn't work, I can see several things:

1. to put the pitch in a variable, you do

    pitch = Get pitch

so that later you can use things like

    printline 'pitch:3'

2. Select... All 0 10

the Select command doesn't have a field that you can give the value 
All. Please read the scripting tutorial.

3. select Pitch untitled

this is a command from the Objects window. You'll have to change the 
context away from the editor, i.e. you should do

    endeditor

just before your first Objects window command.

Praat Picture change to log

Hej everybody,

does anybody know how to change the horizontal axis in Praat Picture to log frequency (Hz)?
I need a praat picture showing LTAS in db (left) and log frequency (bottom).

sound not converted to LTAS

Hej,

I have a problem converting a normal sound to a LTAS object. It takes really long and then occurs a window
saying that it is "out of memory and that there is not enough room for it an its 8 bytes each". What can I do? I
need this LTAS object...

Thanks in advance!

Greets,
Susan
