Overview
Unlock Effortless Audio Creation with this AI Agent
This AI Agent acts as your dedicated Text-to-Speech specialist. It receives text through a simple webhook, then leverages OpenAI's advanced audio generation capabilities to convert that text into high-quality, natural-sounding speech. The generated audio is then sent back as a binary response, ready for immediate use in your applications or content pipelines.
This agent empowers you to automate the production of audio content, enhancing user engagement and accessibility without manual recording or complex software.
Key Features & Benefits
- AI-Powered Speech Synthesis: Utilizes OpenAI's cutting-edge text-to-speech (TTS) models (e.g., the 'fable' voice is pre-configured) for human-like audio output.
- Webhook Integration: Easily trigger audio generation from any system capable of sending a POST request. The agent listens on the
/generate_audiopath. - Direct Audio Output: Responds with binary audio data, perfect for direct playback, saving to a file, or integrating into other services.
- Streamlined Content Production: Automate the creation of voiceovers for videos, audio versions of articles, podcast segments, or dynamic audio responses for chatbots and IVRs.
- Customizable Voice: While preset with the 'fable' voice, you can easily modify the OpenAI node to use other available OpenAI voices to match your brand or style.
- Developer-Friendly: Designed for seamless integration into your existing n8n automation flows and external applications.
Use Cases
- B2C E-commerce: Generate voiceovers for product demo videos or create audio versions of blog posts to improve accessibility and engagement.
- B2B SaaS: Create audio walkthroughs for new feature announcements, onboarding tutorials, or knowledge base articles.
- Solopreneurs: Quickly produce audio content for podcasts, social media voice notes, or YouTube videos from written scripts.
- Automate voice responses for customer support bots or generate dynamic audio for personalized user experiences.
- Head of Automation: Integrate with CRMs or internal tools to provide audio summaries of reports or notifications.
Prerequisites
- An n8n instance (Cloud or self-hosted).
- OpenAI API Key with access to Text-to-Speech (TTS) models (e.g.,
tts-1,tts-1-hd). - Configured OpenAI credentials within your n8n instance.
Setup Instructions
- Download the n8n workflow JSON file.
- Import the workflow into your n8n instance.
- Configure the 'OpenAI' node: In the 'Credential for OpenAI API' field, select your existing OpenAI credentials or click 'Create New Credentials' to add your OpenAI API Key.
- (Optional) Customize the 'Voice' parameter in the 'OpenAI' node if you wish to use a different voice than the default 'fable'. Refer to OpenAI documentation for available voices.
- The 'Webhook' node is pre-configured to listen for POST requests at the path
generate_audio. To trigger the workflow, send a POST request to the webhook URL with a JSON body containing the text to convert. Example:{"text_to_convert": "Hello, this is a test of the AI audio generation."}. - Activate the workflow using the toggle in the top-right of the n8n editor.
- Use the Production URL of the webhook for integrations. The workflow will respond with the binary audio data (e.g., an MP3 file).
