Goal:
Show how to use Elevenlabs to convert text messages into voice messages to make interactions with AI agents more natural and fun.

Scope of application:
This approach is suitable for anyone who wants to revitalize communication with users through AI bots by adding voice responses instead of text ones. It is especially useful for businesses that use chatbots in messengers to improve the user experience.

‍ Tools:

• Elevenlabs account
• n8n account

Go to n8n and create automation, or go to your own one you're working on

Add a node HTTP

Open it and go to settings:

Choose a method POST

In the URL section, type:  https://api.elevenlabs.io/v1/text-to-speech/ + The ID of the voice you need, for example  https://api.elevenlabs.io/v1/text-to-speech/0BcDz9UPwL3MpsnTeUlO

To select the voice you need, go to Elevenlabs in the library section and there will be a +Add button to the right of the voice, after clicking on it, the voice will be added to your My Voices section

In My Voices, to the right of the voice, click View

And copy the ID

Then in n8n:

Activate Send Headers

Create two fields with parameters

and fill them out like this:

1 Name: Content-type

Value: application/json

2 Name: xi-api-key

Value: (Your API key)

To find the API key, go back to Elevenlabs

Click on My Account and select API Keys

And click Create API Key

Copy the key and paste it into the node parameter in n8n

Then activate Send Body

Body content type et Specify body leave it as it is.

Now create two parameters as well

1 Name: text

Value: {{$json.output}} or use Schema mode to add output data from the node you need by dragging and dropping the data block

2 Name: model_id

Value: eleven_multilingual_v2

As a result, the HTTP Request block should look like this:

Next is the next block after HTTP. Create, for example, Telegram and select the SendAudio action

Connect credentials, insert your chat ID and set up the block to receive binary data.

To do this, turn on the slider Binary file

And in Input Binary Field: data (the name of the binary file that you will receive after processing by Elevenlabs, usually data)

Also, in Additional Fields, click on Add Field and choose File name

In this field, enter the full name of the binary file along with its format, namely data.mpeg

It's done.

Now I will be sending audio messages to Telegram. You can also integrate any other messenger supported by n8n.
