Most transcription APIs train on clean audio. Modulate trains on real conversations — noise, overlap, accents, emotion — and ranks #1 on the AMI Meeting Corpus.

Lower Cost. Serious Savings.

On-demand pricing at $0.015/hr with no volume penalties. Teams switching from leading alternatives see 51% cost reduction or more.

Built for Intelligence, Not Just Transcription.

Modulate's API is the foundation for emotion detection, speaker diarization, and conversation analysis. Transcription is just the start.

Better Transcripts. Lower Spend.

Teams switching from leading transcription providers consistently see higher accuracy on real-world audio, fewer downstream corrections, and dramatically reduced infrastructure costs.

Lower Cost Per 1,000 Minutes

Starting at $0.015/hr — up to 90% lower than competing providers at equivalent quality.

Fewer Downstream Fixes

Higher accuracy from the start means less time correcting transcripts in post-processing pipelines.

No Transcript + LLM Patchwork

Modulate's API delivers structured, intelligence-ready output — not just raw text that requires another model to parse.
