Modulate product offering
Product offeringCore offering
Modulate builds voice-native AI models and platforms that analyze audio conversations in real time to detect fraud, deepfakes, toxic behavior, churn risk, and compliance violations. Its flagship Velma enterprise platform is powered by a proprietary Ensemble Listening Model (ELM) architecture coordinating 100+ specialized audio-native sub-models, and is complemented by ToxMod voice moderation for gaming/social platforms plus a suite of self-serve developer APIs for transcription, deepfake detection, PII/PHI redaction, and AI music detection.
Product overview
Modulate offers a unified voice AI platform-and-modules architecture centered on its proprietary Ensemble Listening Model (ELM), branded as Velma. The Velma enterprise platform serves as the core product, exposing conversation intelligence for fraud prevention, AI agent guardrails, compliance, customer retention, and trust & safety use cases through dashboards, APIs, and webhooks. Alongside the platform, Modulate offers ToxMod as a dedicated voice moderation product for gaming and online communities, with a spin-out called VoiceVault for voice-based fraud detection. Velma is also exposed as a self-serve developer API, with five productized model families: Velma Conversation Understanding (the ELM API), Velma Transcribe (speech-to-text), Velma Deepfake Detect, Velma PII/PHI Redaction, and the AI Music Detection API and Music & Speech Detection API for synthetic content identification. These products share the same audio-native ELM architecture but are consumed differently—enterprise platform for configured deployments with SLAs, and APIs for developer integration.
