How to configure Espeak on Ubuntu 21.04

To Configure Espeak on Ubuntu 21.04

Introduction:

Espeak is an open-source, portable speech synthesizer software tool for English and other languages, which is available in a compact size for Linux and Windows. The voice is clear, and the speed is high, but it's not as smooth or natural as larger synthesizers that mimic human speech.

Installation Procedure:

Step 1: Check the OS version by using the below command

root@linuxhelp:~# lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 21.04
Release:	21.04
Codename:	hirsute

Step 2: Check the dependency package GIT by using the below command

root@linuxhelp:~# apt list --installed | grep git

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

Step 3: Check dependency package make by using the below command

root@linuxhelp:~# apt list --installed | grep make

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

automake/hirsute,hirsute,now 1:1.16.3-2ubuntu1 all [installed,automatic]

Step 6: Change to the espeak directory by using the below command

root@linuxhelp:~# cd espeak-ng/

Step 7: Install the espeak by using the below command

root@linuxhelp:~/espeak-ng# ./autogen.sh

Step 9: Run the “make” command to update dependencies by using the below command

root@linuxhelp:~/espeak-ng# make

Step 10: Run “make install” to compile the programs by using the below command

root@linuxhelp:~/espeak-ng# make install

cp -prf espeak-ng-data/* /usr/share/espeak-ng-data
make[2]: Leaving directory '/root/espeak-ng'
make[1]: Leaving directory '/root/espeak-ng'

Step 11: Run the following command to convert the text to speech by using the below command

root@linuxhelp:~/espeak-ng# espeak-ng -v en-us --stdout   "hai how are you" -s 100  > /home/linuxhelp/Music/test.mp3

Step 12: Play the audio as shown in the below image

With this the process of installation and configure Espeak on Ubuntu 21.04 has comes to an end.
