Deepgram Speech AI - Phrase Detector

The Deepgram Phrase detector uses AI to spot times of keywords in speech.

The Deepgram Phrase Detector Add-on locates spoken phrases in recorded calls with high accuracy. Make your app conversation-aware using Deepgram's accurate fuzzy speech search.

  • The Most Accurate Phrase Search

    Deepgram's proprietary fuzzy search uses deep learning algorithms to locate phrases even in noisy, low-quality audio. Unlike transcript-based search, Deepgram's search accuracy improves with longer search phrases and works with specialized vocabulary such as names and other proper nouns.

  • Compliance Monitoring

    Deepgram can help enforce regulatory compliance and check that standards of behavior are being followed by matching a call against a rubric of what should and should not be said.

  • Real-time Notifications

    Escalate an issue or notify a supervisor when red flags show up in a call. You can configure your app to send a notification when Deepgram Phrase Detector finds something amiss.

  • Understand Your Customers

    What's making your customers happy? What are your options for improvement? Discover these trends by searching for competitor mentions, product names, 'I love', or 'cancel my subscription'.
