AI Text-to-Speech Agent (OpenAI)

Overview

This AI Agent leverages OpenAI's advanced text-to-speech (TTS) capabilities to transform written text into high-quality, natural-sounding audio. It acts as a dedicated 'Voice Generation' specialist, empowering you to easily create audio content for diverse business applications directly within your n8n automations. Whether for marketing, training, or accessibility, this agent streamlines the production of voiceovers and audio narrations.

Key Features

• High-Quality Voice Synthesis: Utilizes OpenAI's tts-1 model for natural and realistic voice output.
• Customizable Voices: Supports various voice options provided by OpenAI (e.g., alloy, echo, fable, onyx, nova, shimmer) to match your brand or content style.
• Direct MP3 Output: Generates audio directly in MP3 format, ready for use in podcasts, videos, or applications.
• Simple Configuration: Easily set your input text and choose a voice through straightforward parameters within n8n.
• Seamless n8n Integration: Designed to be a plug-and-play component, triggerable manually or by other automated events in your n8n workflows.
• Scalable Audio Generation: Automate the creation of audio content from dynamic text sources, perfect for batch operations or real-time generation.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to TTS models (e.g., tts-1).
• OpenAI credentials configured in your n8n instance.

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure OpenAI Credentials: In the 'Send HTTP Request to OpenAI's TTS Endpoint' node, select your pre-configured OpenAI credential from the 'Credential for OpenAI API' dropdown. If you haven't added your OpenAI API key to n8n yet, create a new credential in n8n's 'Credentials' section and then select it here.
4. Customize Input: In the 'Set input text and TTS voice' node, modify the input_text field with the text you want to convert. You can also change the voice (available options include: alloy, echo, fable, onyx, nova, shimmer – refer to OpenAI documentation for the latest list).
5. (Optional) Trigger Modification: Replace the 'When clicking "Test workflow"' manual trigger with any other n8n trigger node that suits your automation needs (e.g., Webhook, Schedule, Form Submission).
6. Test and Activate: Run a test to ensure it generates the MP3 audio file correctly. The output binary (MP3 audio) will be available from the 'Send HTTP Request to OpenAI's TTS Endpoint' node for use in subsequent steps (e.g., saving to a file, sending via email). Activate the workflow when ready.
