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 +``` + +![](https://opensource.com/sites/default/files/uploads/linux-toy-cava.gif) + +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! + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/18/12/linux-toy-espeak + +作者：[Jason Baker][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/jason-baker +[b]: https://github.com/lujun9972 +[1]: https://en.wikipedia.org/wiki/2001:_A_Space_Odyssey_(film) +[2]: http://espeak.sourceforge.net/ +[3]: http://espeak.sourceforge.net/voices.html +[4]: https://github.com/karlstav/cava +[5]: https://opensource.com/article/18/12/linux-toy-nudoku
