Description

Reads Pitch object from Praat. Supported formats: text file, short text file.

Usage

1
pitch.read(fileNamePitch, encoding = "UTF-8")

Arguments

fileNamePitch

file name of Pitch object

encoding

File encoding (default: "UTF-8"), "auto" for auto-detect of Unicode encoding

Value

A Pitch object represents periodicity candidates as a function of time.

[ref: Praat help, http://www.fon.hum.uva.nl/praat/manual/Pitch.html]

p$xmin ... start time (seconds)

p$xmax ... end time (seconds)

p$nx ... number of frames

p$dx ... time step = frame duration (seconds)

p$x1 ... time associated with the first frame (seconds)

p$t ... vector of time instances associated with all frames

p$ceiling ... a frequency above which a candidate is considered voiceless (Hz)

p$maxnCandidates ... maximum number of candidates in frame

p$frame[[1]] to p$frame[[p$nx]] ... frames

p$frame[[1]]$intensity ... intensity of the frame

p$frame[[1]]$nCandidates ... actual number of candidates in this frame

p$frame[[1]]$frequency ... vector of candidates' frequency (in Hz)

(for a voiced candidate), or 0 (for an unvoiced candidate)

p$frame[[1]]$strength ... vector of degrees of periodicity of candidates (between 0 and 1)
