Good to know
The key questions.
You can find technical details, voices, and advanced settings in the detailed guide.
Is LinguoAI free?
The LinguoAI source code is freely available. External services and Colab plans may incur costs.
Google restricts the predominant use of external web interfaces in free Colab runtimes without a positive Compute unit balance. Check the Colab terms before starting.
What happens to my files?
On the desktop, you can use local models. In Colab, files are processed on a temporary Google VM; online translators and online voices send data to their provider. Only use content and voices for which you have the necessary rights.
Do I need a powerful graphics card?
No. Processing is also possible on the CPU, but takes longer. A short video is enough to get started. A GPU is optional.
How long does my Colab link work?
Only while the corresponding Colab session and interface are running. The Gradio link is dynamic and should only be shared with people you trust. Download your results in time or save them to Google Drive.
Can I choose faster speech recognition?
Parakeet is an optional CPU speech recognition engine: NVIDIA v3 supports 25 European languages, while primeline specializes in German. Whisper remains the versatile default. Speed and quality depend on the recording and your computer.
Can I upload and download directly in the browser?
Yes. Google Colab provides an interface for your active session. The separate Video Studio is in testing and requires credentials you have received; translation there is still limited.
