Convert text into an MP3 using OpenAI speech synthesis.

[在 Open Flow 中使用](https://console.openflow.run/flows?importUrl=https%3A%2F%2Fraw.githubusercontent.com%2Foomol-lab%2Fawesome-workflow-templates%2F9018120e802d4de0a097610157c565df858c0871%2Fworkflows%2Fgenerate-an-openai-speech-mp3%2Ftemplates%2Fgenerate-an-openai-speech-mp3.openflow.json)

Convert text into an MP3 using OpenAI speech synthesis.

## Setup and use

Connect OpenAI in **Generate MP3 speech**. Run Open Flow with text and a voice; the source example is `The quick brown fox jumped over the lazy dog.` with `alloy`. In n8n, edit **Set input text and TTS voice** and connect an OpenAI credential to the HTTP node. Input is limited to 4,096 characters.

## Behavior

One request sends the text to `tts-1` and returns MP3 audio. Open Flow produces a downloadable `speech.mp3` artifact; n8n returns binary `data`. Failed synthesis or invalid audio stops the run. If you share the recording, disclose that the voice is AI-generated.

OpenAI has [announced the shutdown of `tts-1` on January 6, 2027](https://developers.openai.com/api/docs/guides/text-to-speech). The recommended Realtime API replacement uses a different workflow.

## Changes to the source

*   Remove the redundant literal Authorization header; use the OpenAI connection instead.
*   Validate input and MP3 output, correct the source’s input limit and preserve the audio as a downloadable artifact.
