Values

Description

scrubaudio

false (default),

true

Supply the scrubaudio=true tag to apply the redaction feature to audio. When this option is specified, a zip file containing the redacted audio will return along with the transcript. Sections of audio where sensitive numbers are spoken are replaced with silence. See scrubtext for more information on what constitutes a sensitive number. Refer to scrubaudio for more information on this parameter.

scrubconf

scrubconf=</path/to/file

Used to specify JSON-formatted redaction scrubbing rules to override the default rules. See the scrubtext section for information about default scrubbing rules. Refer to scrubconf for more information on this parameter.

scruboutfmt

mp3 (default), mp3-8...mp3-64, wav

Used to specify the format and bit rate of returned scrubbed audio. When mp3 is specified the default bitrate of 16 kbps is used. Supported mp3 bitrates are 8, 16, 24, 32, and 64 kbps. When wav is specified the returned audio encoding matches that provided as input (aLaw, µ-law, or Linear PCM in WAV format). If wav is specified and transcode=true, the returned audio is LPCM WAV.

scrubsil

false (default), true

Pass the scrubsil=true tag to make redaction remove audio from regions where speech was not detected. This parameter only applies when scrubaudio is set to true. This setting increases security by blanking out audio that could contain sensitive information at a very low signal level, below the Voice Activity Detection (VAD) threshold.

scrubtext

false (default), true

Specify the scrubtext=true tag to apply Voci 's redaction feature to transcript text. Redaction recognizes and removes sensitive numeric values from results. By default, sensitive numbers are any string of numeric digits (as produced when numtrans=true) that do not fit into a “whitelisted” pattern. Refer to scrubtext for more information on this parameter.
