# assetInstallationRequest(supporting:)

Returns an installation request object, which is used to initiate the asset download and monitor its progress.

```
static func assetInstallationRequest(supporting modules: [any SpeechModule]) async throws -> AssetInstallationRequest?
```

## Discussion

If the current status is `.installed`, returns nil, indicating that nothing further needs to be done.

If some of the assets require locales that aren’t reserved, it automatically reserves those locales. If that would exceed [`maximumReservedLocales`](/documentation/Speech/AssetInventory/maximumReservedLocales), then it throws an error.

> Throws: An error if the assets are not supported or no reservations are available.
