Yes and cannot find a solution. It seems to happen only on student chromebooks. Voice can be changed, but has to be done every time a new book is opened. Have you found a solution? I contacted BS and was told to do the following:
1. Go to the Chrome Web Store and install “Chrome OS US English Female HQ.”https://chrome.google.com/webstore/detail/chrome-os-us-english-fema/efdojdlmjknacnljjdedapanceanigkh2. Close all Chrome windows, “Sign out” from the Chromebook, and sign back in.Once the book is loaded, open Settings by selecting the Gear icon on the toolbar, and ensure this voice is selected from the voice selection drop down box near the bottom, then select Save.
I did those things, plus everything else I could think of, and nothing fixed this weird glitch.
