Speech recognition is any means by which you can interface with your computer via spoken word.
This page is designed to identify applications that can facilitate speech recognition and to serve as a guide in installing and using this software in Arch.

'''A note to newcomers:'''
Speech
recognition is something that traditionally has not been well supported in Linux.
If you become interested and choose to dig below the immediate surface, you can expect difficulty in finding documentation or help from the community.

*:As it sounds, Text-To-Speech (or TTS)
will manipulate a string of text into an audio clip.
There are several programs available that perform TTS, some of which are command-line based (ideal for scripting) and others which provide a handy GUI.

It is useful for blind people to be able to use computers but can also be used to simply improve computer experience.

*:This is the most basic form of Speech-To-Text application. These are designed to recognize a small number of specific, typically one-word commands and then perform an action. This is often used as an alternative to an application launcher, allowing the user for instance to say the word “firefox” and have his OS open a new browser window.

*:Full dictation/recognition software allows the user to read full sentences or paragraphs and translates that data into text on the fly. This could be used, for instance, to dictate an entire letter into the window of an email client. In some cases, these types of applications need to be trained to your voice and can improve in accuracy the more they are used.

[[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 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.

Dragon Naturally Speaking software by Nuance is a well-functioning and popular implementation of speech dictation. It is developed for Windows, but has been run sucsessfully in a a linux enviornment using wine. It can be used independently for dictation into other wine programs such as notepad or it can be paired with Platypus to interface with any native linux program. Platypus also provides a feature to control of your OS using voice commands, similar to the programs described in the [[Speech_Recognition#Voiced_Commands | Voiced Commands]] section.
