Let your Linux terminal speak its mind
|
|||
|
|
======
|

eSpeak is an open source text-to-speech synthesizer that can be invoked from the Linux command line.

Greetings from another day in our 24-day-long Linux command-line toys advent calendar. If this is your first visit to the series, you might be asking yourself what a command-line toy even is. We’re figuring that out as we go, but generally, it could be a game, or any simple diversion that helps you have fun at the terminal.
|
|||
|
|
|
|||
|
|
We hope that even if you've seen some of these before, there will be something new for everybody in our series.
|
|||
|
|
|

|
Some of you may be too young to remember, but before there was Alexa, Siri, or the Google Assistant, computers still had voices.
|
|||
|
|
|
|||
|
|
Many of us will never forget HAL 9000 from [2001: A Space Odessey][1] helpfully conversing with the crew (sorry, Dave). But between 1960s science fiction and today, there was a whole generation of speaking computers. Some of them great, most of them, not so great.
|
|||
|
|
|
|||
|
|
One of my favorites is the open source project [eSpeak][2]. It's available in many forms, including a library version you can use to include speech technology in your own project, but it also coms as a command-line program that you can install and use easily. In my distribution, this was as simple as:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ sudo dnf install espeak
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Invoking eSpeak then can be invoked either interactively, or by piping text to it using the output of another program or a simple echo command. There are a number of [voice files][3] available for eSpeak, and if you're especially bored over the holidays, you could even create your own.
|
|||
|
|
|
|||
|
|
A fork of eSpeak called eSpeak NG ("Next Generation") was created in 2015 from some developers who wanted to continue development of the otherwise lightly-updated eSpeak. eSpeak is made available as open source under a GPL version 3 license, and you can find out more about the project and download the source code [on SourceForge][2].
|
|||
|
|
|
|||
|
|
I'll also throw in a bonus toy today, [cava][4]. Because I've been eager to give each of these articles a unique screenshot as the lead image, and today's toy outputs sound rather than something visual, I needed to find something to fill the space. Short for "console-based audio visualizer for ALSA" (although it supports more than just ALSA now), cava is a nice MIT-licensed terminal audio visualization tool that's fun to watch. Below, is a visualization of eSpeak's output of the following:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ echo "Rudolph, the red-nosed reindeer, had a very shiny nose." | espeak
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
Do you have a favorite command-line toy that you we should have included? Our calendar is basically set for the remainder of the series, but we'd still love to feature some cool command-line toys in the new year. Let me know in the comments below, and I'll check it out. And let me know what you thought of today's amusement.
|
|||
|
|
|
|||
|
|
Be sure to check out yesterday's toy, [Solve a puzzle at the Linux command line with nudoku][5], and come back tomorrow for another!
