n8n-nodes-deepgram

n8n-nodes-deepgram

This is an n8n community node package for interacting with the Deepgram API.

It currently includes the following nodes:

• Deepgram Transcriber: Transcribes pre-recorded audio files using the Deepgram API. Supports providing audio via URL or binary file input.
• Deepgram Speaker (TTS): Generates audio from text using the Deepgram Speak API (Text-to-Speech).

n8n is a fair-code licensed workflow automation platform.

Installation Operations Credentials Compatibility Usage Resources License

Installation

Follow the installation guide in the n8n community nodes documentation.

• Go to Settings > Community Nodes.
• Select Install.
• Enter n8n-nodes-deepgram in the Enter package name field.
• Agree to the risks of using community nodes: select I understand the risks, and I want to proceed.
• Select Install.

After installing the node, you can use it like any other node. n8n displays the node in the node panel under Community > Installed.

Operations

• Deepgram Transcriber:
  • Transcribe audio from a public URL.
  • Transcribe audio from an n8n binary file property.
  • Supports various Deepgram models (including Nova 2 and Nova 3).
  • Allows specifying additional options like language, punctuation, diarization, smart formatting, keywords, and callback URL.
  • Optionally append metadata (endpoint, parameters, duration) to the output.
  • Choose between outputting the full raw transcript or just the transcript text.
• Deepgram Speaker (TTS):
  • Convert input text (up to 2000 characters) into spoken audio.
  • Select from various Deepgram Aura voice models.
  • Configure audio output options like encoding (MP3, WAV, etc.), container, sample rate, and bit rate.
  • Outputs the generated audio as an n8n binary file property.

Credentials

Requires Deepgram API credentials. The same credentials work for both the Transcriber and Speaker nodes.

• Go to your Deepgram Console.
• Navigate to API Keys.
• Create a new API key or use an existing one.
• In n8n, create new credentials for the Deepgram Transcriber node.
• Enter your Deepgram API Key.
• (Optional) If using a self-hosted or custom Deepgram endpoint, enter the Base URL.

Compatibility

Tested with n8n version 1.x.

Usage

• Install the package in your n8n instance.
• Add the Deepgram Transcriber node to your workflow.
• Configure the node properties:
  • Select the Input Source Type (URL or Binary File).
  • Provide the Audio URL or Binary Property name.
  • Choose the desired Model.
  • Configure Additional Options as needed (language, punctuate, etc.).
  • Select the Output Format.
  • If using "Transcript Only" format, optionally specify a custom Transcript Field Name (defaults to transcript).
• Connect the node and run your workflow.

Deepgram Speaker (TTS)

• Install the package in your n8n instance.
• Add the Deepgram Speaker (TTS) node to your workflow.
• Configure the node properties:
  • Enter the Text to Speak.
  • Choose the desired Voice Model.
  • Configure Audio Options (encoding, container, sample rate, bit rate) as needed.
  • Specify the Output Binary Property name where the audio data will be stored (defaults to data).
  • (Optional) Provide an Output Filename (e.g., speech.mp3). If left empty, a default filename based on the output format will be used (e.g., deepgram_output.mp3).
• Connect the node and run your workflow. The output item will contain the generated audio in the specified binary property, including the filename.
