Feature Description

Submit an audio noise reduction task.

Authorization Description

When using a sub-account, you need to add the ci:CreateAsrJobs permission to the action in the authorization policy. For all supported Cloud Infinite APIs, see CI action.
When a sub-account uses the asynchronous processing API, it must be granted the cam:PassRole permission. The asynchronous processing API performs COS read-write operations through CAM's "role". The PassRole permission is used for role passing. For details, refer to Cloud Access Management > Write Operation > PassRole API.

Service Activation

To use this feature, you need to bind a bucket in advance and enable Cloud Infinite service.
To use this feature, you need to enable Smart Audio Service in advance via the console or API.
Note:
After binding Cloud Infinite (CI), if you manually perform the unbinding operation for the bucket, you will not be able to continue using this feature.

Use Limits

When using this API, please confirm the related use limits. For details, see Use Limits.

Fee Instructions

This API is a paid service. The generated costs will be charged by CI. For billing details, see smart audio fee.
