tblLVST_TranscriptsAligned_cScoreType
Table Description:
tblLVST_TranscriptsAligned_cScoreType maps the type of the score ("INSERTION",
"DELETION", "SUBSTITUTION"...) to a Constant value. INSERTION 1 A recognition
error. The ASR recognized a word, where there isn't a word in the transcript. DELETION 2 A recognition
error. The ASR failed to recognize a word in the transcript. SUBSTITUTION 3 A recognition error. The
ASR recognized a different word than the corresponding word in the transcript. OOV_INSERTION 4 A
recognition error. The ASR recognzied a word in the grammar, but the corresponding transcript word was
not actually in the grammar. This is really a kind of substitution error, and can help pinpoint when
noise is causing a recognition problem. NOISE_INSERTION 5 A recognition error. The ASR recognized a
word in the grammar, but the corresponding transcript word was not actually in the grammar. This is
really a kind of substitution error, and can help pinpoint when noise is causing a recognition problem.
MATCH 6 A recognition success. The ASR returned a word which corresponds to the correct word in the
transcript. OOV_MATCH 7 A recognition success. The ASR correctly rejected a word from the transcript
that is not in the grammar. NOISE_MATCH 8 A recognition success. The ASR correctly rejected a noise.
This is usually not included in measurements of word accuracy, because it makes the resulting score
highly optimistic. Most ASR's will reject noise correctly. For example, with a digits grammar (0-9,
"Oh"): Transcript: 6 2 code ++NOISE++ 7 dash ++LINE++ ASR Results: 1 4 8 oh 7 The score types:
