Text to Speech (OpenAI)
Configured with HTTP Request. Review the connections and setup before adapting this template.
Node categories in this workflow
- Trigger
- Transform
- Web / API
Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| When clicking "Test workflow" | Trigger | Manual Trigger | See node parameters |
| Set input text and TTS voice | Transform | Edit Fields | See node parameters |
| Send HTTP Request to OpenAI's TTS Endpoint | Web / API | HTTP Request | POST |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.

You can replace this manual trigger with another trigger type as required by your use case.
Configuration Options
Configuration Options
-
"input_text" is the text you would like to be turned into speech, and can be replaced with a programmatic value for your use case. Bear in mind that the maximum number of tokens per API call is 4,000.
-
"voice" is the voice used by the TTS model. The default is alloy, other options can be found here: OpenAI TTS Docs
Output
Output
The output returned by OpenAI's TTS endpoint is a .mp3 audio file (binary).
Credentials
To use this workflow, you'll have to configure and provide a valid OpenAI credential.

Purpose and structure
This folder contains the Text to Speech (OpenAI) workflow. Its executable nodes use httpRequest, manualTrigger, set. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.
Setup
Import inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.
