In readtextgrid: Read in a 'Praat' 'TextGrid' File
readtextgrid 
readtextgrid parses Praat textgrids into R dataframes.
Installation
Install from CRAN:
install.packages("readtextgrid")
Install the development version from Github:
install.packages("remotes")
remotes::install_github("tjmahr/readtextgrid")
Basic example
Here is the example textgrid created by Praat. It was created using New
-> Create TextGrid... with default settings in Praat.
This textgrid is bundled with this R package. We can locate the file
with example_textgrid(). We read in the textgrid with
read_textgrid().
library(readtextgrid)
# Locates path to an example textgrid bundled with this package
tg <- example_textgrid()
read_textgrid(path = tg)
#> # A tibble: 3 x 10
#> file tier_num tier_name tier_type tier_xmin tier_xmax
#> <chr> <dbl> <chr> <chr> <dbl> <dbl>
#> 1 Mary_John_bell.TextGrid 1 Mary IntervalTier 0 1
#> 2 Mary_John_bell.TextGrid 2 John IntervalTier 0 1
#> 3 Mary_John_bell.TextGrid 3 bell TextTier 0 1
#> xmin xmax text annotation_num
#> <dbl> <dbl> <chr> <int>
#> 1 0 1 "" 1
#> 2 0 1 "" 1
#> 3 NA NA <NA> NA
The dataframe contains one row per annotation: one row for each interval
on an interval tier and one row for each point on a point tier. If a
point tier has no points, it is represented with single row with NA
values.
The columns encode the following information:
file filename of the textgrid. By default this column uses the
filename in path. A user can override this value by setting the
file argument in read_textgrid(path, file), which can be useful
if textgrids are stored in speaker-specific folders.tier_num the number of the tier (as in the left margin of the
textgrid editor)tier_name the name of the tier (as in the right margin of the
textgrid editor)tier_type the type of the tier. "IntervalTier" for interval
tiers and "TextTier" for point tiers (this is the terminology used
inside of the textgrid file format).tier_xmin, tier_xmax start and end times of the tier in secondsxmin, xmax start and end times of the textgrid interval or point
tier annotation in secondstext the text in the annotationannotation_num the number of the annotation in that tier (1 for
the first annotation, etc.)
Reading in a directory of textgrids
Suppose you have data on multiple speakers with one folder of textgrids
per speaker. As an example, this package has a folder called
speaker_data bundled with it representing 5 five textgrids from 2
speakers.
speaker-data
+-- speaker001
| +-- s2T01.TextGrid
| +-- s2T02.TextGrid
| +-- s2T03.TextGrid
| +-- s2T04.TextGrid
| \-- s2T05.TextGrid
\-- speaker002
+-- s2T01.TextGrid
+-- s2T02.TextGrid
+-- s2T03.TextGrid
+-- s2T04.TextGrid
\-- s2T05.TextGrid
First, we create a set of paths to read into R.
# Get the path of the folder bundled with the package
data_dir <- system.file(package = "readtextgrid", "speaker-data")
# Get the full paths to all the textgrids
paths <- list.files(
path = data_dir,
pattern = "TextGrid$",
full.names = TRUE,
recursive = TRUE
)
We can use purrr::map_dfr() to read all these textgrids into R, but
note that this way loses the speaker information.
library(purrr)
map_dfr(paths, read_textgrid)

We can use purrr::map2_dfr() and some dataframe manipulation to add

Launching Praat
This tip is written from the perspective of a Windows user who uses git
bash for a terminal. To open textgrids in Praat, you can tell R to call
Praat from the command line. You have to know where the location of the
Praat binary is though. I like to keep a copy in my project directories.
So, assuming that Praat.exe in my working folder, the following would
open the 10 textgrids in paths in Praat.
system2(
command = "./Praat.exe",
args = c("--open", paths),
wait = FALSE
)
Limitations
readtextgrid supports textgrids created by Praat by using Save as text
file.... It uses a parsing strategy based on regular expressions
targeting indentation patterns and text flags in the file format. The
formal specification of the textgrid
format,
however, is much more flexible. As a result, not every textgrid that
Praat can open—especially the minimal “short text” files—is compatible
with this package.

Launching Praat
This tip is written from the perspective of a Windows user who uses git
bash for a terminal. To open textgrids in Praat, you can tell R to call
Praat from the command line. You have to know where the location of the
Praat binary is though. I like to keep a copy in my project directories.
So, assuming that Praat.exe in my working folder, the following would
open the 10 textgrids in paths in Praat.
system2(
command = "./Praat.exe",
args = c("--open", paths),
wait = FALSE
)
Limitations
readtextgrid supports textgrids created by Praat by using Save as text
file.... It uses a parsing strategy based on regular expressions
targeting indentation patterns and text flags in the file format. The
formal specification of the textgrid
format,
however, is much more flexible. As a result, not every textgrid that
Praat can open—especially the minimal “short text” files—is compatible
with this package.
