Automate Text-to-Speech with OpenAI and n8n
detail.loadingPreview
Effortlessly convert text into natural-sounding audio using OpenAI's powerful text-to-speech capabilities, triggered automatically via webhooks. Integrate seamlessly into your workflows to generate audio on demand.
About This Workflow
This n8n workflow automates the process of converting text into speech using OpenAI's advanced text-to-speech models. It leverages a webhook to initiate the audio generation process, making it ideal for dynamic content creation. Upon receiving a POST request with the text to convert, the workflow sends this data to the OpenAI API, specifying a voice and resource type. The generated audio is then immediately returned as a binary response, allowing for real-time integration into applications or further processing within your n8n flows. This workflow is designed for developers and automation enthusiasts looking to embed speech synthesis into their systems.
Key Features
- Webhook Triggered Automation: Initiate text-to-speech conversions via simple HTTP POST requests.
- OpenAI Integration: Harness the power of advanced AI models for high-quality audio generation.
- Customizable Voices: Select from various OpenAI-supported voices to match your audio needs.
- Binary Audio Response: Receive generated audio directly in a format ready for use or further manipulation.
- Flexible Configuration: Easily set up API credentials and customize input text and voice parameters.
How To Use
- Set up the Webhook Node: Configure the
Webhooknode with a unique path (e.g.,generate_audio) and set thehttpMethodtoPOST. EnsureresponseModeis set toresponseNode. - Configure the OpenAI Node: Connect your OpenAI credentials to the
OpenAInode. In theinputfield, use={{ $json.body.text_to_convert }}to dynamically pull text from the webhook's request body. Select your desiredvoice(e.g.,fable). - Connect Nodes: Link the
Webhooknode's output to theOpenAInode's input. - Configure Response Node: Connect the
OpenAInode's output to theRespond to Webhooknode's input. EnsureRespond to Webhookis set torespondWith: 'binary'to return the audio file. - Activate Workflow: Enable the workflow toggle in n8n and test by sending a POST request to your webhook URL with a JSON body containing
"text_to_convert": "Your text here".
