With the AssemblyAI Connector, you can use AssemblyAI's models to process audio data by transcribing it with speech recognition models, analyzing it with audio intelligence models, and building generative features on top of it with LLMs.

Speech-To-Text including many configurable features, such as speaker diarization, custom spelling, custom vocabulary, etc.
Audio Intelligence Models are additional AI models available and configured through the transcription configuration.
LeMUR lets you apply various LLM models to your transcripts without the need to build your own RAG infrastructure for very large transcripts.

Prerequisites

You will need the following to proceed:

An AssemblyAI API key (get one for free)

How to get credentials

You can get an AssemblyAI API key for free by signing up for an account and copying the API key from the dashboard.

Get started with your connector

Follow these steps to transcribe audio using the AssemblyAI connector.

Upload a File

To transcribe an audio file using AssemblyAI, the file needs to be accessible to AssemblyAI. If your audio file is already accessible via a URL, you can use your existing URL.

Otherwise, you can use the Upload a File action to upload a file to AssemblyAI. You will get back a URL for your file which can only be used to transcribe using your API key. Once you transcribe the file, the file will be removed from AssemblyAI's servers.

Transcribe Audio

To transcribe your audio, configure the Audio URL parameter using your audio file URL. Then, configure the additional parameters to enable more Speech Recognition features and Audio Intelligence models.

The result of the Transcribe Audio action is a queued transcript which will start being processed immediately. To get the completed transcript, you have two options:

Handle the Transcript Ready Webhook
Poll the Transcript Status

Handle the Transcript Ready Webhook

If you don't want to handle the webhook using Logic Apps or Power Automate, configure the Webhook URL parameter in your Transcribe Audio action, and implement your webhook following AssemblyAI's webhook documentation.

To handle the webhook using Logic Apps or Power Automate, follow these steps:

Create a separate Logic App or Power Automate Flow

Configure When an HTTP request is received as the trigger:

Set Who Can Trigger The Flow? to Anyone

Set Request Body JSON Schema to:

{
  "type": "object",
  "properties": {
    "transcript_id": {
      "type": "string"
    },
    "status": {
      "type": "string"
    }
  }
}

Set Method to POST

Add an AssemblyAI Get Transcript action, passing in the transcript_id from the trigger to the Transcript ID parameter.
Before doing anything else, you should check whether the Status is completed or error. Add a Condition action that checks if the Status from the Get Transcript output is error:
- In the True branch, add a Terminate action
  - Set the Status to Failed
  - Set the Code to Transcript Error
  - Pass the Error from the Get Transcript output to the Message parameter.
- You can leave the False branch empty.
Now you can add any action after the Condition knowing the transcript status is completed, and you can retrieve any of the output properties of the Get Transcript action.
Save your Logic App or Flow. The HTTP URL will be generated for the When an HTTP request is received trigger. Copy the HTTP URL and head back to your original Logic App or Flow.
In your original Logic App or Flow, update the Transcribe Audio action. Paste the HTTP URL you copied previously into the Webhook URL parameter, and save.

When the transcript status becomes completed or error, AssemblyAI will send an HTTP POST request to the webhook URL, which will be handled by your other Logic App or Flow.

As an alternative to using the webhook, you can poll the transcript status as explained in the next section.

Poll the Transcript Status

You can poll the transcript status using the following steps:

Add an Initialize variable action
- Set Name to transcript_status
- Set Type to String
- Store the Status from the Transcribe Audio output into the Value parameter
Add a Do until action
- Configure the Loop Until parameter with the following Fx code:
```
or(equals(variables('transcript_status'), 'completed'), equals(variables('transcript_status'), 'error'))
```
  This code checks whether the transcript_status variable is completed or error.
- Configure the Count parameter to 86400
- Configure the Timeout parameter to PT24H
Inside the Do until action, add the following actions:
- Add a Delay action that waits for one second
- Add a Get Transcript action and pass the ID from the Transcribe Audio output to the Transcript ID parameter.
- Add a Set variable action
  - Set Name to transcript_status
  - Pass the Status of the Get Transcript output to the Value parameter
The Do until loop will continue until the transcript is completed, or an error occurred.
Add another Get Transcript action, like before, but add it after the Do until loop so its output becomes available outside the scope of the Do until action.

Before doing anything else, you should check whether the transcript Status is completed or error. Add a Condition action that checks if the transcript_status is error:

In the True branch, add a Terminate action
- Set Status to Failed
- Set Code to Transcript Error
- Pass the Error from the Get Transcript output to the Message parameter.
You can leave the False branch empty.

Now you can add any action after the Condition knowing the transcript status is completed, and you can retrieve any of the output properties of the Get Transcript action.

Add more actions

Now that you have a completed transcription, you can use many other actions passing in the ID of the transcript, such as

Get Sentences of Transcript
Get Paragraphs of Transcript
Get Subtitles of Transcript
Get Redacted Audio
Search Transcript for Words
Run a Task using LeMUR

Known issues and limitations

No known issues currently. We don't support Streaming Speech-To-Text (real-time) as it is not possible using Custom Connectors.
