About company
Voice intelligence to identify underage users.
Velma is a frontier model for real conversation — used by enterprises to fight fraud, ensure compliance, and protect users, and by developers to power more accurate real-time agents, transcribe noisy audio more reliably, or detect subtle vocal cues of deepfakes.
Modulate’s enterprise platform brings Velma into workflows, enabling analysis of audio for fraud signals, compliance risk, emotion, and more. The company offers both direct APIs and a fully managed platform for voice analytics, transcription, and deepfake detection.
