Problem Solved

This workflow addresses the challenge of converting French text into spoken audio and subsequently transcribing that audio back into English text. It automates the process of translation and audio generation, saving users time and effort while enhancing language learning and content accessibility.

Workflow Steps

  • Manual Trigger: The workflow begins when the user clicks the 'Execute Workflow' button.
    2. Set Voice ID and Text: It sets the ElevenLabs voice ID and the French text that needs to be converted to audio.
    3. Generate French Audio: The workflow sends a request to the ElevenLabs API to generate audio from the French text.
    4. Transcribe Audio: Once the audio is generated, it is sent to OpenAI's transcription service to convert the audio back into text.
    5. Translate Text to English: The transcribed text is then translated into English using LangChain.
    6. Generate English Audio: Finally, the English text is converted back into audio using ElevenLabs, completing the cycle of translation and audio generation.

    • Customization Guide

    Users can customize this workflow by:
    - Changing Voice ID: Update the voice_id parameter in the 'Set ElevenLabs voice ID and text' node to use a different voice from ElevenLabs.
    - Modifying Text: Edit the text parameter in the same node to input different French text for translation.
    - Adjusting Audio Settings: Users can tweak the voice_settings parameters like stability and similarity_boost in the audio generation nodes to modify the audio output.
    - Integrating Additional Languages: To support other languages, users can add additional translation nodes or modify the existing translation prompts.
