Everything you need to
manage risk—in one place

As with everything in Shield’s platform, Voice is natively built in, not bolted on, enabling enterprise-grade compliance across communication types.

  • No reconciling data points across different systems that don’t talk to each other. All relevant data is now at your fingertips.
  • Manage risk faster and more efficiently with one consistent user experience and interface for audio and written communications.
  • With a centralized source of truth, you can quickly scale coverage and complexity as needed.

Search, review, and analyze voice comms as easily as written comms

Compliance and eDiscovery teams can now investigate spoken conversations with the same precision and control as emails and text messages.

  • Easily spot critical points in conversations with in-line transcription, fully indexed, in the same environment as written communications.
  • Quickly understand who’s saying what, and when, even across low-quality audio, with fully synchronized playback and diarization.
  • Keep those who need to know, in the know, with multiple sharing options of full or trimmed comms with internal and external stakeholders.

Monitor and detect high-risk behavior faster than ever

Account for risk within audio, with the ability to spot early warning signs and investigate them immediately.

  • Ensures compliance across strict financial regulatory requirements including Dodd-Frank, MiFID II, and MAR.
  • Detect stress, deception, and other concerning patterns with robust risk taxonomy, combined with accurate financial and voice-sensitive detections.
  • Skip over false positives and quickly grasp the full picture of conversations with contextualized alerts that explain their reasoning.

Generate highly accurate transcriptions in 99+ languages

Access accurate transcriptions of audio communications, no matter the language or quality of the recording.

  • Immediate language recognition and transcription, with full cultural and linguistic context.
  • Automated, real-time language switching, even mid-conversation, to help you stay on top of what’s being said throughout.
  • Local context, different dialects, and accents all taken into account so that nothing gets lost in translation.
