AssemblyAI has announced significant upgrades to its PII Redaction and Entity Detection features, aimed at enhancing data security and extracting key insights from audio transcripts. According to AssemblyAI, the latest updates include support for PII Text Redaction across 47 languages and the addition of 16 new entity types to its Entity Detection model, bringing the total to 44.

Enhanced PII Redaction Capabilities

The updated PII Text Redaction feature now supports 47 languages, ensuring comprehensive protection of personally identifiable information (PII) across diverse regions. This upgrade allows users to identify and remove sensitive data such as addresses, phone numbers, and credit card details from their transcripts. Additionally, users can generate transcripts with PII removed or use the tool to “beep out” sensitive information in audio files.

An example of how to use the API for PII redaction is provided by AssemblyAI:

import assemblyai as aai

aai.settings.api_key = "YOUR API KEY"

audio_url = "https://github.com/AssemblyAI-Community/audio-examples/raw/main/20230607_me_canadian_wildfires.mp3"

config = aai.TranscriptionConfig(speaker_labels=True).set_redact_pii(
  policies=[
    aai.PIIRedactionPolicy.person_name,
    aai.PIIRedactionPolicy.organization,
    aai.PIIRedactionPolicy.occupation,
  ],
  substitution=aai.PIISubstitutionPolicy.hash,
)

transcript = aai.Transcriber().transcribe(audio_url, config)

for utterance in transcript.utterances:
  print(f"Speaker {utterance.speaker}: {utterance.text}")
  
print(transcript.text)

Users can refer to AssemblyAI’s documentation for more detailed examples and an in-depth dive into the updates.

Expanded Entity Detection

The Entity Detection model has been upgraded with 16 new entity types, allowing for the automatic identification and categorization of critical information in transcripts. This brings the total number of supported entity types to 44, which includes names, organizations, addresses, and more. The model ensures 99% accuracy in major languages, making it a robust tool for extracting valuable insights from audio data.

An example of how to use the API for Entity Detection is also provided:

import assemblyai as aai

aai.settings.api_key = "YOUR API KEY"

audio_url = "https://github.com/AssemblyAI-Community/audio-examples/raw/main/20230607_me_canadian_wildfires.mp3"

config = aai.TranscriptionConfig(entity_detection=True)

transcript = aai.Transcriber().transcribe(audio_url, config)

for entity in transcript.entities:
  print(entity.text)
  print(entity.entity_type)
  print(f"Timestamp: {entity.start} - {entity.end}\n")
