In humlab-speech/superassp: A speech signal processing using various framworks using a wrassp-like interface

Estimates aperiodicity of a speech signal

Description

Aperiodicity is estimated using function for assessing band-aperiodicities using the Definitive Decomposition Derived Dirt-Cheap (D4C) algorithm \insertCiteMorise.2016.10.1016/j.specom.2016.09.001superassp implemented in the WORLD vocoder \insertCiteMORISE.2016.10.1587/transinf.2015edp7457superassp. The the dio \insertCitemorise2010rapidsuperassp pitch algorithm is used to calculate the periodic component.

Usage

aperiodicities(
  listOfFiles,
  beginTime = 0,
  endTime = 0,
  windowShift = 5,
  minF = 70,
  maxF = 200,
  voiced_voiceless_threshold = 0.01,
  explicitExt = "wap",
  outputDirectory = NULL,
  toFile = TRUE
)

Arguments

listOfFiles	A vector of file paths to wav files.
beginTime	The start time of the section of the sound file that should be processed.
endTime	The end time of the section of the sound file that should be processed.
windowShift	The measurement interval (frame duration), in seconds.
minF	Candidate f0 frequencies below this frequency will not be considered.
maxF	Candidates above this frequency will be ignored.
explicitExt	the file extension that should be used.
outputDirectory	set an explicit directory for where the signal file will be written. If not defined, the file will be written to the same directory as the sound file.
toFile	write the output to a file? The file will be written in outputDirectory, if defined, or in the same directory as the soundfile.

Value

An SSFF track object containing two tracks (f0 and corr) that are either returned (toFile == FALSE) or stored on disk.
