This Common Lisp package takes a collection of .TextGrid files and
formant_data.txt files and parses them to produce a .csv file
suitable for import into a data processing environment such as R.
The file expects a set of TextGrid files and a set (potentially a set
of one) of files called formant_data.txt, which consist of lines
having the following format:
<name of .wav file> <timepoint of formant measurement> <F1> <F2>
The script parses the TextGrid files and finds the formant
measurements from the formant_data.txt files.
This is not a full parser for TextGrid files at this stage, but it
does support IntervalTiers. The mark-up scheme is obviously specific
to my project, but it shouldn't be too difficult to tweak it (look at
the parse-file function).
This package is free software, released under the Community Research and Academic Programming License (CRAPL).
