Terms of use.

Your account and recordings.

Use an email address you control and keep your password private. Submit only recordings you are authorized to process. You retain ownership of your content and authorize the processing needed to provide your requested comparison.

Free experience.

Anonymous visitors can compare up to 60 seconds of source audio per UTC day. Verified accounts receive 5 minutes per UTC calendar month, with recordings up to 5 minutes each. Each comparison counts source duration once, regardless of the number of selected models. Pending requests reserve allowance; failed or canceled comparisons release it. Unused allowance does not roll over. Availability and fair-use limits apply.

Scores are comparative estimates, not guarantees of accuracy. Review transcripts before relying on them. The published study does not guarantee results for every recording.
