Ubuntu has a built in screen reader, Orca [1].

"Welcome to Orca Orca is a free, open source, flexible, and extensible screen reader that provides access to the graphical desktop via speech and refreshable braille. Orca works with applications and toolkits that support the Assistive Technology Service Provider Interface (AT-SPI), which is the primary assistive technology infrastructure for Linux and Solaris. Applications and toolkits supporting the AT-SPI include the GNOME Gtk+ toolkit, the Java platform's Swing toolkit, LibreOffice, Gecko, and WebKitGtk. AT-SPI support for the KDE Qt toolkit is being pursued." [1] https://help.ubuntu.com/stable/ubuntu-help/a11y-screen-reade...
