[Bug 1870642] Re: Upgrade espeak-ng in Binoic Beaver to at least 1.49.2+dfsg-8 (from 1.49.2+dfsg-1)

[Steven Presser]

These directions document upgrading eSpeak NG on Ubuntu 18.04.  eSpeak
NG is the default voice for Orca.

On Ubuntu 18.04, the default version of eSpeak NG does not speak certain
types of punctuation (including the vertical bar (|), caret (^),
greater-than (>) and less-than (<)) when used in Orca's "say-all" or
speaking flat review lines or words, even with punctuation set to all.
This is not particularly critical for most uses, but these characters
are critical for programming and systems administration.

Upgrading eSpeak NG as follows will result in this punctuation being
read correctly when punctuation is set to all and a say-all or flat
review line or word command is issued.

COMMAND NOTATION

This document uses the dollar sign ($) as a prompt at the beginning of
each command.  This indicates that a command can be run as a non-
elevated/non-root user.  Do not type the dollar sign when typing the
command.

In many directions, the hash (#) is used to indicate that a command
should be run as root or using elevated privileges.  In these
directions, this notation is not used.  Instead commands are given with
sudo when elevated privileges are required.

INSTRUCTIONS

1. Check running version of eSpeak NG. The package name is the second
field on each line, while the version is the third field.

$ dpkg -l | grep espeak

The output should be:

ii  espeak-ng-data:amd64                       1.49.2+dfsg-1                                amd64        Multi-lingual software speech synthesizer: speech data files
ii  libespeak-ng1:amd64                        1.49.2+dfsg-1                                amd64        Multi-lingual software speech synthesizer: shared library
ii  speech-dispatcher-espeak-ng                0.8.8-1ubuntu1                               amd64        Speech Dispatcher: Espeak-ng output module

2. If this is less than 1.49.2+dsfg-8 (As of 2020-04-01, it is
1.49.2+dsfg-1 on Ubuntu 18.04), these directions are known to work.

3. Download the requisite packages:

$ wget http://mirrors.kernel.org/ubuntu/pool/main/e/espeak-ng/libespeak-ng1_1.49.2+dfsg-8_amd64.deb
$ wget http://mirrors.kernel.org/ubuntu/pool/main/e/espeak-ng/espeak-ng-data_1.49.2+dfsg-8_amd64.deb

4. Then install them:

$ sudo dpkg -i libespeak-ng1_1.49.2+dfsg-8_amd64.deb espeak-ng-
data_1.49.2+dfsg-8_amd64.deb

5. Check the installed eSpeak NG version:

$ dpkg -l | grep espeak

The output should be:

ii  espeak-ng-data:amd64                       1.49.2+dfsg-8                                amd64        Multi-lingual software speech synthesizer: speech data files
ii  libespeak-ng1:amd64                        1.49.2+dfsg-8                                amd64        Multi-lingual software speech synthesizer: shared library
ii  speech-dispatcher-espeak-ng                0.8.8-1ubuntu1                               amd64        Speech Dispatcher: Espeak-ng output module

6. Reboot the machine.  Turning Orca off and on several times may also
pick up the change, but this has not been entirely reliable in testing.

7. Test that the following characters are correctly read by issuing a
flat review speak line (Orca+i)

8. Enjoy :)

These directions pull in an upgraded version of eSpeak NG from Ubuntu
19.04.  By doing so, we ensure that your system will continue to receive
upgrades to eSpeak NG as new software is added to Ubuntu 18.04, as long
as the new software is greater than the version we have just installed.
