Automated Voice Generation and Playback Workflow
detail.loadingPreview
Effortlessly generate speech from text and play it back automatically. This workflow streamlines voice content creation by integrating custom Python scripts with n8n automation.
About This Workflow
This n8n workflow automates the process of generating spoken audio from text and then playing that audio. It starts with a manual trigger to initiate the process. Next, it uses a 'Set' node to define the text content and the desired voice (e.g., 'af_sarah') for speech synthesis. This information is then passed to a 'Run python script' node, which executes a custom Python script ('voicegen.py') to perform the actual voice generation. Finally, the generated audio file (assumed to be 'output.mp3') is read and played back using the 'Play sound' node. This provides a simple yet powerful way to create and consume audio content programmatically.
Key Features
- Automated Voice Synthesis: Convert text into spoken audio using custom Python scripts.
- Configurable Input: Easily define the text and voice parameters for generation.
- Seamless Playback: Automatically play the generated audio file once created.
- Manual Trigger Initiation: Start the workflow on demand.
How To Use
- Start Node: Trigger the workflow manually.
- Passing Variables Node: Configure the
jsonOutputparameter to define thetextyou want to convert to speech and thevoicealias for the desired voice (e.g.,{ "voice": "af_sarah", "text": "Your text here!" }). - Run Python Script Node: Ensure your Python script
voicegen.pyis located atC:\KOKORO\voicegen.pyand is capable of accepting the text and voice as command-line arguments. Thecommandparameter is set topython C:\KOKORO\voicegen.py "{{ $json.text }}" "{{ $json.voice }}" 1. - Play Sound Node: Specify the
fileSelectorparameter with the path to your generated audio file (e.g.,D:/output.mp3). This node will read and play the file.
