In usagi5886/intonation: Linguistic analysis of speech fundamental frequency

Description Details Note Author(s) References See Also Examples

This package consists of the functions used in Albin (2015) for various tasks relating to speech fundamental frequency, including

manipulating Pitch objects from the phonetics software Praat,
visualizing F0 data in a way that retains rich information from the acoustic signal, and
creating and plotting a schematic quantitative representation ('stylization') of an F0 track.

Package:	intonation
Type:	Package
Version:	1.1
Date:	2016-07-12
License:	GNU General Public License (Version 3 or later)
Imports:	audio, PraatR

This package has two dependencies: audio and PraatR. To install the latter, follow the steps under "Installation" on the PraatR homepage. (Note, however, that that only functions in this package relying on PraatR are ToPitch and F0RangeFinder.)

In addition to some sample data (HelloWorld), the package includes the following functions:

`Spectrogram`	Create a spectrogram of an audio file
`F0RangeFinder`	Cycle through each soundfile in a folder and determine F0 range for each
`ToPitch`	Use Praat to generate a Pitch object
`ReadPitch`	Read a Pitch object into R
`RichVisualization`	Visualize the F0 data in a Pitch object
`Stylize`	Create a 'stylization' (i.e., a schematic representation) of F0 an track
`PlotStylization`	Draw a stylization on an open plot of an F0 track

# Create paths to the WAV file and Pitch object textfile included in the package
WavePath = paste(R.home("library"),"intonation","HelloWorld.wav",sep="/")
PitchPath = sub(WavePath,pattern=".wav",replacement=".Pitch",fixed=TRUE)

# Draw a spectrogram of the audio data in a soundfile
Spectrogram(WavePath)

## Not run: 
# Create a Pitch object from this soundfile
ToPitch( Input=WavePath, Output=PitchPath, Range=c(69,135) )
## End(Not run)

# Read this Pitch object into R
head( ReadPitch( PitchPath ) )

# Plot the F0 data contained therein as a 'rich visualization'
RichVisualization( PitchPath=PitchPath, WavePath=WavePath, 
                   Labels = c("hello","world"), Divisions_ms = c(132,648,1257) )

# Create a stylization of the F0 track
Stylization = Stylize( PitchPath, VertexIndices=c(211,489,1123) )

# Superimpose this stylization on the rich visualization
PlotStylization(Stylization)
