A call analytics solution must produce searchable transcripts with sensitive values removed. In what order should the steps run?

選択肢

1. Redact the audio before transcription by muting the segments where a speaker is likely to be reading out a number, then transcribe the muted recording
2. Translate the transcript into a common language and then index it, so that calls in different languages can be searched with a single set of query terms
3. Transcribe the audio, detect and redact the sensitive values, and only then index the redacted version of the text rather than the original wording of it
4. Index the transcript first so the calls become searchable as early as possible, then detect the sensitive values and redact them inside the index in a follow-up pass
