Synthesizing Voice From the Command Line
I don't do a lot of audio/video stuff with my system, but the other day I had the urge to see if there was some voice synthesis software available on Linux and it turned out that I already had it installed: it's called Festival. Turns out there are a number of voice synthesis and analysis packages available.
Festival is, according to the website:
Festival offers a general framework for building speech synthesis systems as well as including examples of various modules. As a whole it offers full text to speech through a number APIs: from shell level, though [sic] a Scheme command interpreter, as a C++ library, from Java, and an Emacs interface. Festival is multi-lingual (currently English (British and American), and Spanish) though English is the most advanced.
As far as simple commands, Festival comes with two: saytime and text2wave. Saytime does what you would expect, it speaks the time (as well as outputting the spoken text to stdout). Note though, the time that is output tends to be less than specific:
$ saytime The time is now, just after half past 10, in the morning.
A wave file of the output is attached (time.wav).
The second command that comes with Festival is text2wave which converts text read from stdin to a .wav file output:
$ echo Your job has completed | text2wave >job.wav $ aplay job.wav # OR $ echo Your job has completed | text2wave | aplay
The wave file is attached (job.wav).

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
