First go to this website:

  • If you're not already, you'll have to sign in
  • In My Devices, click on BIG JAMBOX
  • Follow the instructions to download and install the Jawbone_Updater-x.x.x.exe and click continue
  • Then be redirected to the Voices and Tones page, which are the .dfu files
  • Choose a voice you like and download it
  • Now the speaker must be turned off and connected with the USB cable to the computer
  • Double-click on the file (the Jawbone_Updater must NOT be running for this to work, you'll know if it is running if you see the "J" icon on the task bar (bottom right on Windows and I believe upper left on Mac) click it and then click "quit")
  • After double-clicking the file click OK on a window after finding your speaker
  • Now you just have to wait, the "J" icon will appear and become red and if you click on it you can see the percentage. This takes around 5 to 10 minutes.
