Measure and analyze child and adult coarticulatory patterns via mel frequency spectra. Repo contains scripts and data necessary to replicate analyses in Cychosz (submitted). (https://psyarxiv.com/26uyb)
get_mel_spec_bythirds.py - option to compute coarticulation spectrally (spectral distance) by taking spectra from middle third of two adjacent phones and computing average spectrum from each phone; also computes phone and word duration; generates filename+mel_spectrum.csv which can be read into R for post-processing
To execute this script:
- In terminal, move inside of corpus directory that contains .wav and .TextGrid files with corresponding names
cd specify/directory/location/corpus_directory- Run script over entire directory
python3 specify/file/location/get_mel_spec_bythirds.py walk1_rename_participants.R - gives participants anonymous IDs; not included in repo as it contains deanonymized participant information; generates thirds_CV.anonymized.csv
2_map_words_modified.R - reads in thirds_CV.anonymized.csv; selects word environments; calculates Euclidean distance between spectral vectors; modified version that does not include deanonymized participant information is included in repo; generates mapped_words_anonymized.csv
3_ch3_results.Rmd - reads in mapped_words_anonymized.csv; generates Results section of paper
3_ch3_results.pdf - compiled results section from 3_ch3_results.Rmd
3_ch3_results.tex - tex source of results section from 3_ch3_results.Rmd
Quechua_coartic_manuscript.pdf - compiled paper, including Results section
Quechua_coartic_manuscript_source.tex - tex source of Quechua_coartic_manuscript.pdf
3_ch3_results_files/ - directory containing figures generated by 3_ch3_results.Rmd
thirds_CV.anonymized - dataframe generated by 1_rename_participants.R
mapped_words_anonymized.csv - dataframe generated 2_map_words_modified.R; required to compile 3_ch3_results.Rmd (Results)
coartic_as_transition.py - option to compute coarticulation temporally (more dynamic); one technique used to measure coarticulation in Cychosz et al. (2019)
get_mel_spec.py - option to compute coarticulation spectrally (spectral distance); one technique used to measure coarticulation in Cychosz et al. (2019)
