textgrid_editor

textgrid_editor is yet another python module for modifying with Praat TextGrid files. Also provides APIs for editing TextGrids and converting between TextGrids and pandas DataFrames.

Features:

1. Regex Parsing: It uses regular expressions (re) to identify the specific structure of a Praat file (headers, item classes etc.).

2. Pandas Integration: It stores the annotation data in a Pandas DataFrame. This makes it very powerful for analyzing, filtering, or modifying large amounts of phonetic data.

3. Gap Filling: It includes a utility function fill_interval_df_gaps to "repair" TextGrids by filling in silent/empty spaces between defined intervals, ensuring the timeline is continuous.

4. Serialization: It can convert the Python object back into the text string format required by Praat files. Dict and DataFrame are also supported.

5. Support TextGrid editing, that is, cropping/extending and concatenating TextGrids.
