# Rate limits

Requests to the `/understanding` endpoint — covering [Translation](/speech-understanding/translation), [Speaker Identification](/speech-understanding/speaker-identification), and [Custom Formatting](/speech-understanding/custom-formatting) — are rate limited per account, measured as requests within a 60-second window. A single request can include multiple features and counts once against this limit.

## Default limits

| Account type | Rate limit (requests/min) |
| ------------ | ------------------------- |
| Free         | 2                         |
| Paid         | 30                        |
