# Downloads _(STT only)_

The following STT models are available for download.
These are compatible with TrulyNatural STT SDK [7.9.0](https://doc.sensory.com/tnl/7.9/changes/index.md#v7.9.0) and later.

Contact your account representative or [Sensory sales](https://doc.sensory.com/tnl/7.9/contact.md#contact) for
additional languages and customizations.

**Filename key:**

`-nlu`

- Model includes an NLU component that identifies intents and entities.

`-pnc`

- Model includes punctuation and capitalization.

Larger models are more accurate but also require more CPU cycles.
