To install precompiled package of eSpeak NG on Linux, use standard package manager of your distribution. (Probably is very high, eSpeak NG will be included in package repository).
E.g. for Debian-like distribution (e.g. Ubuntu, Mint, etc.) execute command:
sudo apt-get install espeak-ng
For RedHat-like distribution (e.g. CentOS, Fedora, etc.) execute command:
sudo yum install espeak-ng
For ArchLinux-like distribution (e.g. SteamOS, EndeavourOS, etc.) execute command:
sudo pacman -S espeak-ng
To install precompiled binaries of eSpeak NG on Windows:
open (https://github.com/espeak-ng/espeak-ng/releases) and click on Latest release and then appropriate *.msi file, e.g. espeak-ng-20191129-b702b03-x64.msi
Execute downloaded installer package.
if espeak-ng is compiled and installed without pcaudiolib compiled and installed before, then calling it simply
espeak-ng hello
doesn’t produce any sound.
Then usual workaround with sending data standard output and piping it to aplay (Lubuntu) or paplay (Ubuntu) works:
espeak-ng hello --stdout|aplay
But, when pcaudiolib is compiled and installed and espeak-ng is reconfigured, recompiled and reinstalled again, simple call works properly.
If espeak-ng is built from source code, ensure that libpulse-dev package is installed, or pcaudiolib built and installed and, when do ./configure command, check that status says:
PulseAudio support: yes
Then recompile and install espeak-ng again.
If Linux distribution doesn’t support pulseaudio sound system (or it doesn’t work):
Remove pulseaudio package install alsa:
sudo apt purge pulseaudio
sudo apt autoremove
sudo apt install --reinstall alsa
Reboot
sudo reboot
Recompile espeak-ng with ` –with-pulseaudio=no` support:
./autogen.sh
./configure --prefix=/usr --with-pulseaudio=no
make -B
sudo make install
