We're excited to announce that Entity Detection is now available for streaming (real-time) speech-to-text with Nova 3, Nova 2, Nova, and Enhanced models.

detect_entities=true

Previously available only for pre-recorded audio, you can now identify and extract over 50 unique entity types in real-time streaming transcriptions, including email addresses, names, locations, phone numbers, social security numbers, and more.

Key features for streaming Entity Detection:

• Model support: Nova 3, Nova 2, Nova, and Enhanced models only (not available for Base models or Flux)
• Real-time detection: Entities are included in final results (is_final: true messages)
• Enhanced formatting: Includes both value (formatted) and raw_value (original spoken text) fields when formatting is enabled
• Automatic inclusion: Empty entities array returned when no entities are detected

Example usage:

const connection = deepgram.listen.live({
  model: "nova-3",
  language: "en-US",
  smart_format: true,
  detect_entities: true,
});
