Wikipedia defines speech analytics as analyzing recorded calls to gather customer information.

That page says it includes automatic speech recognition and is known for setting the topic against the emotional character of the speech.

It says applications can spot keywords on live audio or as a later pass on a recording.

It says word error rate compares a transcription with a reference, and that word error rate is not always what a search user needs.

A transcript is text. It is not proof of the label someone adds afterward.

Keep the audio, the transcript, and the label in three boxes. A fluent transcript can still contain the wrong word.
