If params correct

For n8n, this automated workflow streamlines text-to-speech generation by integrating with Elevenlabs' API. It validates input parameters and triggers a voice generation process, responding with audio output or error messages as needed. This solution enhances efficiency in video production and other applications requiring voice synthesis, saving time and improving productivity.

Target Audience

This workflow is ideal for:
- Content Creators: Those who need to generate voiceovers for videos or podcasts quickly.
- Developers: Individuals looking to integrate text-to-speech functionalities into their applications using Elevenlabs API.
- Marketers: Professionals who want to create engaging audio content for advertisements or promotional materials.
- Educators: Teachers or trainers who wish to convert written materials into audio formats for better accessibility.

Problem Solved

This workflow addresses the challenge of converting text into speech efficiently using the Elevenlabs API. It simplifies the process by providing a webhook endpoint that can be triggered with specific parameters, ensuring that users can automate voice generation without manual intervention. This is particularly beneficial for those who require consistent and high-quality audio output for various applications.

Workflow Steps

  • Webhook Trigger: The workflow starts when a POST request is sent to the /generate-voice endpoint with the required parameters: voice_id and text.
    2. Parameter Validation: The workflow checks if both voice_id and text parameters are provided and exist. If either is missing, it triggers the error response.
    3. Generate Voice: If the parameters are valid, the workflow makes an HTTP POST request to the Elevenlabs API to generate the voice audio using the provided voice_id and text.
    4. Respond to Webhook: After successfully generating the voice, the workflow responds back to the original webhook request with the generated audio in binary format.
    5. Error Handling: If validation fails, the workflow responds with a JSON error message indicating invalid inputs.

    • Customization Guide

    To customize this workflow:
    - Change the API Key: Update the custom authentication credentials in n8n with your Elevenlabs API key to ensure successful API calls.
    - Modify Parameters: Adjust the voice_id and text parameters in the webhook request to use different voices or texts as needed.
    - Add Additional Logic: You can enhance the workflow by adding more conditions or processing steps based on your requirements, such as logging or additional API calls.
    - Adjust Response Types: Change the response format in the Respond to Webhook node if you need to return different types of data or status codes.
