| 15 | +# Power automate batch transcription |
| 16 | + |
| 17 | +Batch transcription is used to transcribe a large amount of audio in storage. Batch transcription can access audio files from inside or outside of Azure. This article describes how to use the [Power Automate batch transcription connector](https://learn.microsoft.com/connectors/cognitiveservicesspe/) to transcribe audio files from an Azure Storage container. |
| 18 | + |
| 19 | +You can also use Batch Transcription in Power Platform applications (Power Automate, Power Apps, Logic Apps) via the [Batch Speech-to-text Connector](https://learn.microsoft.com/connectors/cognitiveservicesspe/) with your own Speech resource. Learn more about [Power Platform](https://learn.microsoft.com/power-platform/) and the [connectors](https://learn.microsoft.com/connectors/). |
| 20 | + |
| 21 | +When source audio files are stored outside of Azure, they can be accessed via a public URI (such as "https://crbn.us/hello.wav"). Files should be directly accessible; URIs that require authentication or that invoke interactive scripts before the file can be accessed aren't supported. |
| 22 | + |
| 23 | +You can specify one or multiple audio files when creating a transcription. We recommend that you provide multiple files per request or point to an Azure Blob storage container with the audio files to transcribe. The batch transcription service can handle a large number of submitted transcriptions. The service transcribes the files concurrently, which reduces the turnaround time. |
| 24 | + |
| 25 | + |
| 26 | + |
| 27 | +## Create the Azure Blob Storage container |
| 28 | + |
| 29 | +When audio files are located in an [Azure Blob Storage](../../storage/blobs/storage-blobs-overview.md) account, you can request transcription of individual audio files or an entire Azure Blob Storage container. |
| 30 | + |
| 31 | + |
| 32 | + |
| 33 | +Follow these steps to create a new storage account and container. |
| 34 | + |
| 35 | +1. Go to the [Azure portal](https://portal.azure.com/) and sign in to your Azure account. |
| 36 | +1. <a href="https://portal.azure.com/#create/Microsoft.StorageAccount-ARM" title="Create a Storage account resource" target="_blank">Create a Storage account resource</a> in the Azure portal. Use the same subscription and resource group as your Speech resource. |
| 37 | +1. Select the Storage account. |
| 38 | +1. In the **Data storage** group in the left pane, select **Containers**. |
| 39 | +1. Select **+ Container**. |
| 40 | +1. Enter a name for the new container and select **Create**. |
| 41 | + |
| 42 | + |
| 43 | + |
| 44 | + |
| 45 | + |
| 46 | +## Upload files to the container |
| 47 | + |
| 48 | +When audio files are located in an [Azure Blob Storage](../../storage/blobs/storage-blobs-overview.md) account, you can request transcription of individual audio files or an entire Azure Blob Storage container. You can also [write transcription results](batch-transcription-create.md#destination-container-url) to a Blob container. |
| 49 | + |
| 50 | +Follow these steps to upload [wav, mp3, or ogg](batch-transcription-audio-data.md#supported-audio-formats) files from your local directory to the Azure Storage container that you created previously. |
| 51 | + |
| 52 | +1. Go to the [Azure portal](https://portal.azure.com/) and sign in to your Azure account. |
| 53 | +1. <a href="https://portal.azure.com/#create/Microsoft.StorageAccount-ARM" title="Create a Storage account resource" target="_blank">Create a Storage account resource</a> in the Azure portal. Use the same subscription and resource group as your Speech resource. |
| 54 | +1. Select the Storage account. |
| 55 | +1. Select the new container. |
| 56 | +1. Select **Upload**. |
| 57 | +1. Choose the files to upload and select **Upload**. |
