Description

Phoneme curves

Format

Elements of phoneme:
..$learn: learning sample of curves. fdata class object with: i.- "data": Matrix of class fdata with 250 curves (rows) discretized in 150 points or argvals (columns).
, ii.- "argvals", iii.- "rangeval": range("argvals"), iv.- "names" list with: main an overall title "Phoneme learn", xlab title for x axis "frequencies" and ylab title for y axis "log-periodograms".

..$test: testing sample of curves. fdata class object with: i.- "data": Matrix of class fdata with 250 curves (rows) discretized in 150 points or argvals (columns).
, ii.- "argvals", iii.- "rangeval": range("argvals"), iv.- "names" list with: main an overall title "Phoneme learn", xlab title for x axis "frequencies" and ylab title for y axis "log-periodograms".

..$classlearn:learning class numbers (as factor). Factor levels: "sh" 1, "iy" 2, "dcl" 3, "aa" 4 and "ao" 5.

..$classtest: testing class numbers (as factor). Factor levels: "sh" 1, "iy" 2, "dcl" 3, "aa" 4 and "ao" 5.
