help needed in setting up Emacspeak via APT

[Rich Morin <rdm@xxxxxxxxxxx>]

I'm creating an accessibility-focused VirtualBox VM, based on Ubuntu Linux.
My hope is that this VM will be a useful add-on to various personal computer
operating systems, including Linux, macOS, and Windows.

I'd like to include Emacspeak, but the "apt install emacspeak" command asks
for some information which I don't have.  More generally, I don't know how
to hand this information in to APT so that it can proceed automagically.

The first dialog says:

  emacspeak speech server configuration

  The /etc/emacspeak.conf file will be configured so that the command
  '/usr/bin/emacspeak' will start Emacs with emacspeak support using this server.                               

  You may change the selection later by running 'dpkg-reconfigure emacspeak' as root,
  or temporarily override the selection by setting the environment variable DTK_PROGRAM.
 
  Default speech server:

    DECtalk 3
    DECtalk Express
    DECtalk Multivoice
    Software DECtalk
    ViaVoice Outloud
    a speech server on another computer
    espeak
    sound card with Software DECtalk

    <Ok>

The second dialog says:

  emacspeak speech server configuration

  If a hardware device is used to generate speech, please enter the Unix device file
  associated with it, such as '/dev/ttyS0' or '/dev/ttyUSB0'.

  If you use a software method to generate speech, please enter 'none'.

  Hardware port of the speech generation device:

  none

Comments, clues, suggestions?
