Modulate

Modulate is a voice AI company based in Cambridge, Massachusetts, building audio-native voice intelligence for trust, safety, and conversation understanding. Its Velma-2 platform exposes a suite of REST (batch) and WebSocket (streaming) model APIs — multilingual and English speech-to-text transcription with speaker diarization, deepfake (synthetic voice) detection, emotion and accent detection, PII/PHI tagging and redaction, language detection, and music/speech and AI-music detection — alongside Velma conversation analysis (behaviors, topics, sentiment, participant roles) and the ToxMod voice-safety product for gaming and social platforms. Authentication is via an X-API-Key header (an api_key query parameter for WebSocket streams), billed per hour of audio processed. Backed by Sierra Ventures.

Modulate publishes 11 APIs on the APIs.io network, including Velma 2 Accent Batch API, Velma 2 Ai Music Detection Batch API, Velma 2 Batch API, and 8 more. Tagged areas include Company, Artificial Intelligence, Voice AI, Speech-to-Text, and Transcription.

The Modulate catalog on APIs.io includes 7 event-driven AsyncAPI specifications.

Modulate’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 22 more developer resources.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate — a tool list derived
    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
