HelloWorld: Synthesized voice saying "hello world", plus accompanying...

In usagi5886/intonation: Linguistic analysis of speech fundamental frequency

Description

• The WAV file was created using the Flite English Synthesis Demo by selecting cmu_us_rms.flitevox under "Choose voice", entering the text Hello, world!, and hitting "Download!".

• The Pitch object was created in Praat with the "To Pitch..." command with a time step of 1 millisecond (0.001 seconds) and a F0 range of 69-135 Hertz.

• The TextGrid was also created in Praat and has one interval tier named "words".

Details

The sole tier ("word") of the TextGrid contains the labels "<SIL>", "hello", "world", and "<SIL>". The boundaries occur at roughly 0.000, 0.132, 0.648, 1.257, and 1.355 seconds.

Source

The synthesis used to create the WAV file was created by Flite using a demo built with GoFlite.

Examples

# Create paths to all three files
WavePath = paste(R.home("library"),"intonation","HelloWorld.wav",sep="/")
PitchPath = sub(WavePath,pattern=".wav",replacement=".Pitch",fixed=TRUE)
TextGridPath = sub(WavePath,pattern=".wav",replacement=".TextGrid",fixed=TRUE)

# Read the WAV file into R using load.wave() (from the 'audio' package)
SoundObject = load.wave(WavePath)

# Read the Pitch object into R using ToPitch() (another function in this package)
Frames = ReadPitch( PitchPath )
head(ReadPitch) # Inspect the results

# Import the TextGrid (in unaltered form) with the base-R function 'readLines()'
readLines(TextGridPath)
