No text field was focused when the paste happened, so it landed nowhere — but the text is safe on your clipboard. Click into any text field and paste it with ⌘V (Mac) or Ctrl V (Windows). See Usage for how this works.
Each transcription overwrites the clipboard by design, so your spoken text is never lost. Voicefall does not restore previous clipboard contents; paste your transcription first, then re-copy what you need.
Check your network connection and microphone. Mixed Chinese-English is a core strength of Voicefall, so try speaking naturally at a normal pace rather than switching languages word by word.
Check that no other app has captured that key. Some keyboard tools, remappers, or games grab Right Alt; close or reconfigure them and try again.
The beta build is not yet notarized by Apple, so the first launch is blocked. Right-click the app → Open → Open again. See the Permissions guide for details.
Check that Voicefall has system Microphone permission and that the correct input device is selected in your system sound settings.
