TextGrid filename in csv?

[. PAL Anusuya]

Dear all, 

Thanks, Yannick, for making Parselmouth. It's really awesome. 

I need to find the duration of the sound files for each syllable according to the annotated textgrid. I find the initial time (in my script, it is xmin), the final time (in my script, it is xmax), and the syllable label (in my script, it is text) according to the python script gien below. And, finally, I save the output as a .csv file. 

The script is given below for your reference. Also, one of the sound files and the textgrids are attached. There is no problem, and it works absolutely fine. 

I was just wondering if there is any way to also add the respective file name of the Textgrid (for example, s1_ba1_chase_iso.TextGrid) as an output along with xmin, xmax, and text. 

Any suggestions would really be helpful. 

Thanks,

Anu

df = pd.DataFrame(np.column_stack([text_list, xmin_list, xmax_list]),columns=['text', 'xmin', 'xmax'])
df.to_csv("textgrid.csv", index=False)

Hi, 

The problem is solved :-) if I add two lines in the for loop: 

for textgrid_file in glob.glob(r"C:\Users\anusu\Maram_Tone\ba\ba_chase\*.TextGrid"):
    grid = textgrids.TextGrid(textgrid_file)
    # Assume "syllables" is the name of the tier
    # containing syllable information
    for syll in grid["Mary"]:

        # if syll.containsvowel():

        # Convert Praat to Unicode in the label
         label = syll.text.transcode()
         text_list.append(syll.text)
         xmin_list.append(syll.xmin)
         xmax_list.append(syll.xmax)

         filename = os.path.join(textgrid_file)
         filename_list.append(filename)

However, a new problem arises. In some of my files, the name of the tier (Mary) is the same; see the attached. In those files, I need only to select the first or second item (depending on the situation). Getting the "Mary" in the first item (item [1]) is problematic, as it does not stop and reads the second item in the list. 

Does anyone have any idea how to just read the first item of the textgrid? 

Thanks, 

Anu

Hi Anu

I'm not familiar with the textgrids library (I tend to use TextGridTools/tgt), and it's completely unrelated to Parselmouth, so I don't think I can help you more than the documentation for this textgrids library.

Do note that Python uses 0-based indexing, so [1] is the second item of a list.

Kind regards

Yannick

I see. Thanks. Yannick, for your prompt reply.

Hello, 

me too, i need to calculate the duration of all syllabes, mais, i don't konw how to read and write the script. So i want to consult your scripts, it is possible ? 

Thanks
