Piper voices are natural voices that run on your device, one download per voice. LuceVoce offers French, Italian and Spanish Piper voices in the voice picker, and you can add other Piper voices from a file.

Download a Piper voice

  1. Open a book and choose the voice button in the bottom bar.
  2. Find a voice with the PIPER label. It shows the size of its download, between 30 and 120 MB.
  3. Choose Download next to it.

LuceVoce shows the progress, and you can stop with Cancel download. When it is done, choose the voice to use it. Every downloaded file is checked, so a damaged download is never used.

Add a voice from a file

You can add a voice you downloaded yourself:

  • A Piper voice: its .onnx file, its .onnx.json file and its MODEL_CARD, or a zip holding them.
  • A LuceVoce pack, a file ending in .lvpack.

The note under Packs in Settings > Voice says where Piper voices are published, with a link (Open the Piper voices repository), and which three files to get.

Windows

  1. Open Settings > Voice.
  2. Under Packs, choose Add voice from file….
  3. Pick the three files of the voice together, or the pack.

You can also drop the files on the LuceVoce window, or double-click a .lvpack file in File Explorer.

Mac

  1. Open Settings > Voice.
  2. Under Packs, choose Add voice from file….
  3. Pick the three files of the voice together, or the pack.

You can also drop the files on the LuceVoce window, or double-click a .lvpack file in the Finder.

iPhone and iPad

  1. Open Settings > Voice.
  2. Under Packs, choose Add voice from file….
  3. Pick the three files of the voice together in the Files picker, or the pack.

Check the licence and install

Before anything is installed, LuceVoce shows the voice's name, kind, language, size and licence, and the licence text when there is one. The licence of a Piper voice comes from its model card. A voice whose licence is non-commercial, share-alike, for research only or unknown is marked Personal use only: you may use it to read your own books, not to make audio for sale. If it replaces a voice you already have, LuceVoce says that too.

  1. Read the details.
  2. Choose Install, or Cancel to leave without installing.

LuceVoce checks each file as it copies it. When it is done, the voice is in the voice list with the other Piper voices.

See and remove the voices you added

Settings > Voice > Packs lists the voices and packs you added, with their kind, language, size and licence, and a Personal use only mark where it applies.

To remove one, choose the delete button next to it (its name is Remove followed by the voice's name), then choose Remove to confirm. Its files are deleted from this device.

Good to know

  • A voice you add can read French, Italian, Spanish, Brazilian Portuguese, Hindi or Romanian. A voice in another language is refused, and LuceVoce names the language.
  • A Piper voice added without its model card has no licence information, so LuceVoce treats it as for personal use only.
  • Read each voice's model card and keep to its licence.
  • If a pack is damaged or a file has changed, nothing is installed and your other voices stay as they were.
  • On the Mac, iPhone and iPad, you can share the voices you added with your other devices through sync. See Share your books between devices.
  • On Windows and Mac, Piper voices copied into the models/piper-personal folder inside LuceVoce's data folder are listed too.
