What is Modulate?
Modulate is a voice intelligence platform built around Velma, an audio-native AI understanding engine that listens to audio conversations and surfaces fraud, customer churn, compliance violations, and toxic behavior before they become incidents. Unlike traditional transcription-plus-LLM pipelines that discard voice signals, Velma analyzes 7 layers of audio data including words, intent and behavior, tone and emotion (20+ emotions), prosody, speaker dynamics, deception and stress cues, and acoustic authenticity for deepfake detection.
The platform offers multiple products and APIs: ToxMod for real-time voice moderation in gaming and social platforms (detecting harassment, hate speech, grooming, toxicity), VoiceVault for AI-powered fraud prevention in finance and contact centers, Velma-2 for production-grade voice AI with multilingual transcription and synthetic voice detection, plus specialized APIs for Speech-to-Text ($0.03/hr), Deepfake Detection (98.9% accuracy, #1 on Hugging Face), PII/PHI Redaction, and Music Detection. Velma ships with 150+ key behaviors detected instantly including vishing, account impersonation, deepfake detection, social engineering, threats-based harassment, suicidal ideation, script adherence, halluncination detection, and renewal risk.
Modulate is designed for enterprise teams and developers building voice AI applications. Primary users include gaming studios and social platforms needing trust & safety solutions, contact centers and fintech companies requiring fraud detection, enterprises implementing AI agent guardrails, customer success teams focused on retention, and developers integrating voice intelligence APIs. The platform supports 20+ languages, operates with low latency for real-time monitoring, and processes over 20 million minutes of audio daily with 56+ million hours of conversations improved.

Frequently asked questions about Modulate
What is Velma and how is it different from transcription plus LLM?
Velma is an audio-native understanding engine that analyzes 7 layers of voice data including words, intent, behavior, tone, emotion, prosody, speaker dynamics, deception cues, and acoustic authenticity. Traditional transcription+LLM pipelines discard voice signals and only capture words, losing intent, emotion, sarcasm, stress cues, and deepfake detection. Velma leverages acoustic signals to understand conversations like a human, capturing 20+ emotions and detecting synthetic voices with 98.9% accuracy.
What is ToxMod used for?
ToxMod is Modulate's voice moderation product for gaming and social platforms that monitors live voice conversations in real time to detect harassment, hate speech, threats, grooming, toxicity, and other harmful behaviors. Unlike text-based moderation, ToxMod understands how something was said—not just what was said—making it far more effective at catching abuse while preserving authentic connection. It supports 20+ languages and scales for millions of concurrent users without latency.
How does Modulate detect deepfakes and synthetic voices?
Modulate's Deepfake Detection API is #1 on Hugging Face with 98.9% accuracy for detecting synthetic audio. Velma's acoustic authenticity layer analyzes voice signals to identify voice cloning, identity spoofing, synthetic voice attacks, and caller ID spoofing in real time. The model is trained on hundreds of millions of hours of real conversations and can distinguish authentic human voices from AI-generated or cloned audio.
What fraud behaviors does Velma detect?
Velma detects 150+ behaviors including vishing, account impersonation, deepfake detection, feigned ignorance, bargaining manipulation, coercion manipulation, AI agent manipulation, identity spoofing, synthetic voice attack, social engineering, caller ID spoofing, credential harvesting, payment diversion, insurance claim fabrications, warranty fraud, voice cloning, account takeover, unauthorized transfer, and phishing via voice. These work across contact centers and fintech for real-time fraud prevention.
Does Modulate support real-time voice analysis?
Yes, Modulate operates with low latency for real-time monitoring. Velma can analyze live or pre-recorded audio and produce near-instant results via API. The platform supports streaming over WebSocket for real-time captions and per-frame synthetic voice detection. ToxMod detects harmful behaviors as they happen, enabling warnings, interventions, or automated actions in real time without killing the conversation.
What languages does Modulate support?
Modulate supports 20+ languages with cultural context understanding. The platform includes multilingual speech-to-text capability through Velma-2, which delivers production-grade voice AI with accurate transcription across languages. This enables global gaming studios, contact centers, and social platforms to moderate and analyze voice conversations across diverse user bases.
Is Modulate compliant with data privacy regulations?
Yes, Modulate is built for enterprise compliance following ISO 27001 security processes and HIPAA-compliant practices. The platform is designed to operate within GDPR, CCPA, and EU AI Act requirements. Your data stays yours—Modulate never trains on your conversations, and you control how your voice AI audio is used. Every flag traces to a specific moment in the call with built-in bias controls for high-risk compliance requirements.
How customizable is Velma for specific business use cases?
Every business is different, and Velma supports infinite behavior customizations. You can describe what matters to your use case in natural language or upload documents, and Velma uses audio signals to surface those specific behaviors. The platform ships with 150+ key behaviors detected instantly but allows customization from natural language prompts or document uploads to detect problems specific to your product, users, and industry.
What APIs does Modulate offer for developers?
Modulate offers multiple APIs: Velma for voice intelligence and behavior detection, Speech-to-Text API ($0.03/hr) with multilingual transcription and speaker diarization, Deepfake Detection API (#1 on Hugging Face, 98.9% accuracy), PII/PHI Redaction API for detecting and redacting sensitive data from live voice streams, and Music Detection API to identify hold music and non-speech segments.
