+For any base or [custom model](how-to-custom-speech-deploy-model.md) endpoint you can delete all available logs, logs for a given time frame, or a particular log based on its Log ID. The deletion process is done asynchronously and can take up to one day depending on the amount of log files.

 ### Delete all logs or logs for a given time frame
 
-To delete all logs or logs for a given time frame, you use [Endpoints_DeleteBaseModelLogs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteBaseModelLogs) (for base model endpoint) or [Endpoints_DeleteLogs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteLogs) (for custom model endpoints) request of the [Speech-to-text REST API](rest-speech-to-text.md).
+To delete all logs or logs for a given time frame:
+
+- Base models: Use the [Endpoints_DeleteBaseModelLogs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteBaseModelLogs) operation of the [Speech-to-text REST API](rest-speech-to-text.md). 
+- Custom model endpoints: Use the [Endpoints_DeleteLogs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteLogs) operation of the [Speech-to-text REST API](rest-speech-to-text.md).
+
+Optionally, set the `endDate` of the audio logs deletion (specific day, UTC). Expected format: "yyyy-mm-dd". For instance, "2023-03-15" results in deleting all logs on March 15th, 2023 and before. 
 
 ### Delete specific log
 
-To delete a specific log by ID, you use [Endpoints_DeleteBaseModelLog](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteBaseModelLog) (for base model endpoint) or [Endpoints_DeleteLog](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_DeleteLog) (for custom model endpoints) request of the [Speech-to-text REST API](rest-speech-to-text.md).
