TextGrid

Reading, writing, modifying Praat TextGrid files in Python. Handles three different TextGrid formats: short, long and chronological. Robust against minor deviations from the standard Praat output, such as in the annotation files of the Corpus Gesproken Nederlands. This robustness comes at a price; parsing is slower than using the TextGrid parser included in the NLTK toolkit. This code, however, can handle more TextGrid formats than NLTK.

Usage

Reading a TextGrid file:

with open('/path/to/textgridfile', 'r') as f:
    my_textgrid = TextGrid.read(f)

Writing a TextGrid to a file:

with open('/path/to/outputfile', 'w') as f:
    my_textgrid.write(f)

Selecting a tier by name:

my_tier = my_textgrid['Words']

Selecting a tier by number:

my_tier = my_textgrid[0]

Deleting a tier:

del my_textgrid['Word']

Getting and setting a tier’s attributes:

print my_tier.name, my_tier.start, my_tier.end
my_tier.start = 0.0

Getting, modifying and deleting an interval in a tier:

print my_tier[0].mark, my_tier[0].start, my_tier[0].end
my_tier[0].mark = 'word'
del my_tier[0]

Iterating over the tiers:

for tier in my_textgrid:
    print tier.name

Iterating over tiers and intervals:

for tier in my_textgrid:
    print tier.name
    for interval in tier:
        print '\t' + interval.mark

Getting the transcription for a tier:

print my_tier.transcription

Convert a TextGrid to json for easy program interoperability:

print my_textgrid.to_json()

Read from json:

my_textgrid.from_json(json_string)

etc.
