eSpeak is a compact open-source software speech synthesizer for English and other languages, for Linux and Windows. In this article, we will explain how you can install the command like tool eSpeak and its GUI alternative Gespeaker on your Ubuntu. Here is some basic intro to the two tools:
eSpeak: This command-line tool takes input in the form of a text string, input file, and also from stdin and plays the input in a computer-generated voice. This speech synthesizer supports 107 languages and accents.
Gespeaker: Gespeaker is a free GTK+ frontend for espeak. It allows you to play a text in many languages with settings for voice, pitch, volume, and speed. The text read can also be recorded to WAV file for future listening.
We have run the commands and procedures mentioned in this article on a Ubuntu 18.04 LTS system.
Install and Use eSpeak on Ubuntu
eSpeak is easily available on the official Ubuntu repositories and can easily be installed through the command line using the apt-get command. Please follow these steps to install eSpeak via the command line.
Open your Terminal application either through the system Application Launcher Search or through the Ctrl+Alt+T shortcut.
The next step is to update your system’s repository index through the following command:
$ sudo apt-get update
This helps you in installing the latest available version of a software from the Internet. Please note that only an authorized user can add, remove and configure software on Ubuntu.
Now you are ready to install eSpeak; you can do so by running the following command as sudo:
$ sudo apt-get install espeak
The system might ask you the password for sudo and also provide you with a Y/n option to continue the installation. Enter Y and then hit Enter; the software will be installed on your system. The process may, however, take some time depending on your Internet speed.
You can check the version number of the application, and also verify that it is indeed installed on your system, through the following command:
$ espeak --version
Use eSpeak for Text to Audio conversion
Through the eSpeak utility, you can easily listen to your specified text aloud. There are two ways through which you can listen to an input string:
1. Use the following command to listen to the text specified in the inverted commas:
$ espeak "enter the text that you want to listen to"
2. Enter the following command and then hit Enter:
On the prompt that appears, enter the text you want eSpeak to say and then hit Enter.
You can enter as many lines of text as you want. Whenever you want to quit the utility, simply hit Ctrl+C
There are many other ways you can use the application; please use the following command to view help on those:
$ espeak --help
However, this is one of the very useful ways you can use this application, i.e, to listen to text from a text file. Use the following syntax to specify the text file whose text you want espeak to say out aloud.
$ espeak -f filename.txt
If you ever want to remove eSpeak installed through the above mentioned method, please use the following command to do so:
$ sudo apt-get remove espeak
The following command will help you in removing any additional packages that were installed with eSpeak or any other software, for that matter:
$ sudo apt-get autoremove
