Redact Words in the Audio

You can configure Media Server to redact words that appear in an audio track, replacing them with either a beep or with silence. The Media Server installation includes an example session configuration that demonstrates how to configure audio redaction (configurations/examples/SpeechToText/AudioRedaction.cfg).

The example configuration includes the following steps:

Words are redacted only if they are recognized correctly by speech-to-text. Sometimes the recognized word might be incorrect but the correct word was one of the alternatives considered by Media Server. In this case you could consider setting the parameter MatchWordsThreshold in the speech-to-text task, so that alternative words can be considered as matches to the list of MatchWords. However, be aware that reducing the threshold might result in some words being redacted unnecessarily. If you want to see alternative words in the speech-to-text results, set the configuration parameter AlternativeWordsThreshold.
