Modulate

What it does

Modulate builds audio-native AI that analyzes dozens of audio signals in each utterance. Its Velma model suite covers deepfake detection, language and accent detection, emotion, transcription, and PII redaction. The Modulate Platform and ToxMod apply these models to enterprise voice intelligence and content moderation.

Modulate focuses on what voice carries beyond words. Its Ensemble Listening Model architecture combines what is said with how it is said, and the site lists models for deepfake detection, AI music detection, language detection, emotion detection, accent detection, audio event detection, transcription, and PII or PHI redaction. The Modulate Platform is aimed at enterprise teams that want to catch fraud, compliance violations, and risky agent behavior, while ToxMod targets content moderation for social and gaming communities. Developers can reach the same models through the Modulate API, which the site describes as self-serve with one key and five model families. The public pages give few concrete numbers. Pricing is listed as pay-as-you-go access and enterprise plans, but no rates appear in the captured text, and there is no statement about a free plan, so cost at scale is hard to judge from the site alone. Buyers should also ask which languages and accents are covered and how audio and transcripts are stored and redacted.
