How to redact audio in the watcher instantly


The Automatic Audio Redaction feature identifies 32 categories of Personally Identifiable Information (PII) which can be redacted within a few clicks. Applying AI Audio within the Watcher effectively streamlines the redaction workflow for users interested in detecting and redacting the same PII from hundreds of audio files.

For example, a call center with thousands of hours of recorded customer service calls that need to be used for training purposes. Once the Watcher is set up to redact the specific PII (names, emails, phone numbers etc.), the recordings can be added to the input folder and they will be automatically processed.  The fully redacted audio will be added to a new folder, free of any manual work or revision!

For those who prefer visual learning this YouTube video will guide you through how to redact PII from audio files in The Watcher.
