One of the types of objects in Praat.
An object of type Confusions represents a confusion matrix, with stimuli as row labels and responses as column labels. The entry at position [i][j] represents the number of times response j was given to the stimulus i.
Suppose you have two objects A and B. In one way or another, you have acquired the following confusions: δAA = 6, δAB = 2 , δBA = 1, and δBB = 7.
You can create a simple text file like the following:
"ooTextFile" ! to make Praat recognize your file
"Confusion" ! The line that tells Praat about the contents
2 "A" "B" ! Number of columns, and column labels
2 ! Number of rows
"A" 6 2 ! Row label A, A-A value, A-B value
"B" 1 7 ! Row label B, B-A value, B-B value
This text file can be read with the Read from file... command.
