Run M-x term RET. At the Run program: prompt, accept the
proposed shell or enter another executable and press RET. Emacsvox
currently makes the selected Term window fill the frame when term or
ansi-term starts. This changes only the window layout: it does not kill
the buffers that were displayed in the other windows.
Term handles terminal emulation, while the child program handles its prompts, input, and completion. Emacsvox observes the rendered Term buffer and adds speech feedback and review commands. See Term Mode in The GNU Emacs Manual for the emulator itself and emacsvox-eterm in Emacsvox Reference Manual for the complete Emacsvox API inventory.
