🎙️ Live Translation (Push-to-Talk) Guide

🚀 NEW FEATURE: Walkie-Talkie Style Translation

The live translation feature works like a walkie-talkie - hold a key to record, release to translate and speak!

🎮 How to Use Live Translation

Step 1: Start Translation Mode

  1. Configure your microphone, target language, and voice
  2. Click "▶️ Start Translation"
  3. The live translation panel will appear

Step 2: Use Push-to-Talk

  1. Hold SPACE (default key) to start recording
  2. Speak while holding the key
  3. Release the key to stop recording
  4. Watch the translation process in real-time!

Step 3: Watch the Process

The interface shows you exactly what's happening:

🎤 What you said: "Hello, how are you today?"
🌍 Translation: "Hola, ¿cómo estás hoy?"

🔧 Customizable Keybind

Change Your Push-to-Talk Key:

  1. Click "Change Key" button in the live translation panel
  2. Press any key to set it as your new push-to-talk key
  3. Or click "Reset to Space" to go back to default

Popular Key Options:

  • Space (default) - Easy to reach
  • KeyV - V key for "voice"
  • KeyT - T key for "talk"
  • ControlLeft - Left Ctrl key
  • AltLeft - Left Alt key

🎯 Live Translation Process

When you use push-to-talk, here's what happens:

  1. 🎤 Recording: "Recording... (release key to translate)"
  2. 📝 Transcribing: "Converting speech to text..."
  3. 🌍 Translating: "Translating to target language..."
  4. 🔊 Speaking: "Speaking..." (plays through virtual microphone)
  5. ✅ Ready: "Hold [KEY] to record"

📊 Real-Time Display

The live translation panel shows:

Left Side - What You Said:

  • Shows your original speech in real-time
  • Updates as speech-to-text processes your voice
  • Shows "Listening..." while recording

Right Side - Translation:

  • Shows the translated text
  • Updates after translation completes
  • Shows "Waiting for speech..." when idle

Status Indicator:

  • Gray dot: Ready to record
  • Red pulsing dot: Currently recording
  • Status text: Shows current process step

🎵 Audio Output

The translated audio is played through the virtual microphone, which means:

  • Other applications (Zoom, Teams, Discord) can hear the translation
  • The translation acts as your "voice" in calls
  • Perfect for real-time multilingual communication

🔍 Debug Information

Enable the debug console to see detailed logs:

  • Recording status and audio data size
  • Speech-to-text processing
  • Translation results
  • Audio synthesis and playback

⚡ Quick Tips

  1. Hold Firmly: Make sure to hold the key down while speaking
  2. Speak Clearly: Better speech = better translation
  3. Wait for Processing: Let each translation complete before starting the next
  4. Check Debug: Use debug console to troubleshoot issues
  5. Test First: Use "🧪 Test Translation" to verify everything works

🎯 Perfect For:

  • Video Calls: Translate your speech for international meetings
  • Gaming: Communicate with players who speak different languages

  • Accessibility: Help with language barriers in real-time
