wer

systemds.operator.algorithm.wer(R: Frame, H: Frame)

This built-in function computes the word error rate (WER) defined as wer = (numSubst + numDel + numIns) / length(r)

Parameters:

• R – Input frame of reference strings, shape: [N x 1]

• H – Input frame of hypothesis strings, shape: [N x 1]

Returns:

Output matrix of word error rate per pair of strings, shape: [N x 1], where W[i,1] = wer(R[i,1], H[i,1])
