AI Audio Translator Workflow (French to English) | n8n

Translate French to English with AI audio—end to end in n8n

This AI Audio Translator Workflow (French to English) | n8n takes French text, generates spoken French audio, transcribes it back to text, then translates and produces an English audio file—all automated inside n8n.

What this workflow does

• Generates spoken French audio from your input text using ElevenLabs.
• Transcribes the French audio back into text using OpenAI.
• Translates the transcribed text into English.
• Generates an audio file of the English translation (again using ElevenLabs).
• Uses a Manual Trigger so you can run it on demand.

Use cases

• Multilingual support: convert French responses into natural-sounding English voice output.
• Content localization: turn French scripts into English narration for videos, podcasts, or training.
• Operational translation: quickly translate and re-voice internal updates without manually recording audio.
• Workflow testing: validate French→English audio translation pipelines using your own text.
