🔊 How to use it
1. Capture system audio
Select system audio capture inside the app. This lets TransEcho listen to sound that plays on your computer, such as:
- Meeting audio
- Video sound
- Online classes
- Live streams
- Calls in speaker mode
2. Pick your languages
Choose the language you hear and the language you want to read or hear back. TransEcho sends the audio through speech to text, then into translation, then into subtitles and voice output.
3. Turn on subtitles
Subtitles appear on screen in real time. This helps when you want to read the translation while listening to the source audio.
4. Turn on voice output
If you want spoken translation, enable text to speech. TransEcho will speak the translated text after it is processed.
5. Adjust the view
You can keep the subtitle window visible while you work. This is useful for long sessions and for following fast speech.

🧭 Simple setup tips
