Modulate
What is Modulate?
Modulate is a voice intelligence platform that analyzes audio conversations for transcription, moderation, fraud prevention, and operational insights. Its Velma models combine spoken words with acoustic signals such as tone, emotion, accent, and synthetic-voice indicators. ToxMod focuses on real-time voice safety for gaming, social, and AI-companion communities, while VoiceVault addresses voice fraud and impersonation risks. Developers can access individual models or broader conversation analysis through REST and WebSocket APIs. Modulate offers free account access and limited credits for API evaluation, while larger platform and enterprise deployments use usage-based or tailored pricing.
