Modulate

Modulate is an enterprise voice AI platform and API for gaming, contact centers, fintech, and communications teams that need real-time understanding of voice conversations.

Key capabilities include:

• Velma (Ensemble Listening Model) for voice-native analysis of sentiment, emotion, nuance, intent, and high-accuracy transcription, designed to recognize behaviors like aggression, complaints, deception, and policy violations.
• Real-time audio intake and insights via integrations with CCaaS, VoIP, and telephony providers, enabling teams to monitor conversations, analyze performance, and generate structured insights.
• Risk and safety detection for use cases such as fraud prevention, harassment and toxic behavior detection (ToxMod), and AI voice agent guardrails.
• Deepfake Detection API for detecting synthetic or manipulated voice.

Pricing: Deepfake Detection API starts at $0.25/hour; other pricing is not listed.

What makes it notable is its voice-native ensemble architecture focused on understanding real conversations (not only transcribed text) and its production scale, including 20+ million minutes of audio analyzed daily and reported impact across hundreds of millions of conversations.
