You can tell LuceVoce what to do instead of pressing a button: play, pause, the next chapter, chapter 5, faster. It helps when you can't see the screen well, or when your hands are busy. Your words are heard on your device only.

Turn on voice commands

Voice commands are off until you turn them on.

  1. Open Settings > Reading.
  2. Under Voice commands, turn on Voice commands.

The first command asks whether LuceVoce may use the microphone and speech recognition.

Windows

Voice commands use the same speech model as voice notes, so download one first in Settings > Study, under Voice notes > Speech model. See Record a voice note.

Give a command

Windows

Press C while reading, or Ctrl+Alt+C from any app.

Mac

Press C while reading, or ⌃+⌥+C (Control, Option and C) from any app.

iPhone and iPad

Tap the text with two fingers, or press the microphone (Voice command) that appears in the top bar.

A short sound tells you LuceVoce is listening, and reading pauses so it can hear you. Say one command. When you stop talking, LuceVoce does it, and reading carries on if it was reading before.

What you can say

Say What happens
play Reading goes on
pause Reading pauses
next chapter, previous chapter The next or the previous chapter
chapter 5 (any number) That chapter
start of the chapter Back to the start of this chapter
next sentence, previous sentence The next or the previous sentence
back, forward 15 seconds back or forward
faster, slower A faster or a slower voice
where am I The chapter and how far you are in the book, said aloud
help The list of commands, said aloud
cancel Stop listening without doing anything

When reading is paused and you move somewhere, LuceVoce tells you where you are now, for example "Chapter 3: The castle".

Choose the language of the commands

Commands can be in English or in French. By default they follow the language of LuceVoce. To use the other one, open Settings > Reading and, under Voice commands, choose The language of the commands.

Good to know

  • Your words are heard on your device. Nothing is kept and nothing is sent anywhere.
  • You can change Ctrl+Alt+C (on the Mac, ⌃+⌥+C) in Settings > Shortcuts, under Anywhere in Windows or Anywhere on the Mac: Give a voice command.
  • On Windows, LuceVoce answers with a Windows voice in the commands' language. With no Windows voice in that language, such as French on a PC with only English voices, the answer is shown instead of said.
  • If speech recognition is off for LuceVoce in your device's settings, or your device can't hear that language by itself, no command is given and a message says why.
  • While you are recording a voice note, finish it first; then give the command.
