# Power automate batch transcription

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.

This article describes how to use [Power Automate](/power-automate/getting-started) and the [Azure Cognitive Services for Batch Speech-to-text](/connectors/cognitiveservicesspe/) to transcribe audio files from an Azure Storage container. The logs and results of the transcription are stored in the same container.

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/).

In addition to [Power Automate](/power-automate/getting-started) to automate repetitive tasks, you can use the Batch Transcription connector in other [Power Platform](/power-platform/)applications including Power Apps and Logic Apps.

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.
21
+
The connector uses the [Batch Transcription REST API](batch-transcription.md), but you don't need to write any code to use the connector. If the connector doesn't meet your requirements, you can use the [REST API](rest-speech-to-text.md#transcriptions) directly.

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.

> Try more Speech features in [Speech Studio](https://aka.ms/speechstudio/speechtotexttool) without signing up or writing any code.
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.
