PII redaction
Redact personally identifiable information with redact=pii|pci|numbers
PII redaction automatically removes personally identifiable information from transcripts before the results reach your application. Sensitive data is replaced in the transcript text and word-level output.
Usage
Add one or more redact query parameters to a streaming WebSocket URL:
# Redact personal information
wss://api.aldea.ai/v1/listen?redact=pii&encoding=mp3
# Redact payment card data
wss://api.aldea.ai/v1/listen?redact=pci&encoding=mp3
# Combine multiple redaction types
wss://api.aldea.ai/v1/listen?redact=pii&redact=pci&encoding=mp3
# Redact all supported types
wss://api.aldea.ai/v1/listen?redact=true&encoding=mp3Redaction types
| Value | What it redacts |
|---|---|
pii | Person names, email addresses, phone numbers, physical addresses, Social Security numbers |
pci | Credit card numbers, bank account numbers |
numbers | Dates, phone numbers, Social Security numbers, credit card numbers |
true | All PII types combined |
The redact parameter is repeatable. You can combine multiple types in a single request (e.g., ?redact=pii&redact=pci).
Redaction mode
Control how redacted content appears in the transcript with the redact_mode parameter:
| Mode | Description | Example output |
|---|---|---|
mask | Replaces characters with asterisks | My SSN is ***-**-**** |
redact | Removes the content entirely | My SSN is |
replace | Substitutes with a type label | My SSN is [SSN] |
