Free voice transcription software software for linux

Ventrilo is the next evolutionary step of Voice over IP (VoIP) group communications software. Ventrilo is also the industry standard by which all others measure them selves as they attempt to imitate its features.
By offering surround sound positioning and special sound effects on a per user, per channel, per server or global configuration level the program provides each user the option to fully customize exactly how they wish to hear sounds from other users or events.
Ventrilo is best known for its superior sound quality and minimal use of CPU resources so as not to interfere with day to day operations of the computer or during online game competitions. It is also preferred for the simple user interface that any first time computer user can very quickly learn because the most commonly used features are immediately visible and can be activated with a single click of the mouse.

The Vovida SIP stack is an implementation of the protocol defined in RFC 2543, the Session Initiation Protocol, which can be used to initiate voice connections (phone calls) over IP networks.

It offers an object-oriented C++ API as well as sample applications demonstrating its use.

Phone for voice modem is only a simple wrapper for the chat program, which allows you to call some numbers on the hayes-compatible modem.

Mr. Voice is a specific-purpose Perl/Tk front-end for an MP3 database.
It was written to provide an easy-to-use MP3 solution for the production booth of an improv comedy troupe, and as such is tailored to providing quick searches and playback of MP3s that are split up into categories.
While not intended to be a standalone desktop MP3 player, others in a similar situation may find it useful.
What is Mr. Voice? A way to have a ton of audio at your disposal, and to be able to call up just the clip you need, just when you need it. If youre running any sort of production that needs audio, such as improv shows, theatre, church events, that sort of thing, Mr. Voice can help. It handles a wide variety of audio formats (MP3, OGG, WAV, AAC, WMA), can do queueing and playlisting, and has a powerful SQL database backend (without needing the overhead of a big database engine like MySQL).
Plus, its 100% free and open-source.
What isnt Mr. Voice? A general-purpose MP3 player. In fact, it doesnt play audio at all by itself - it farms that off to an audio player like XMMS or WinAmp. Its also probably not a wonderful iTunes replacement. Sure, you can categorize and search audio files, but its not designed to become a jukebox.
Enhancements:
- A new option under the Online Preferences to edit the XML-RPC (Mr. Voice Online) URL that is used (in case I need to change it again). It was hardcoded into the program before.
- Fixed bugs that were causing strange quote marks to appear in song and category names.
- Display the song filename in the "Edit Song" menu. Suggested by Bill in Portland.
- Display the time of a song next to the hotkey listing. Suggested by Ted in Chapel Hill.
- Added an option under the File menu to export the song list from your Mr. Voice database as either a text file or Microsoft Excel spreadsheet. Suggested by Ted in Chapel Hill.

It runs on Linux and Windows systems, and supports Text-To-Speech (most notably Realspeak and Festival), multithreading, Barge In, 3 Party Conference, G3 Fax etc.
It has a very simple interface, allowing fast creation of Telephony applications, like e.g. Voiceboxes, Authentication systems, automatic Callcenters etc.
Languages supported include Java, C++, Perl and Python. The source code for Caiviar is freely available.
Enhancements:
- several bugfixes.
- delay (echo) of the connect() function has been greatly reduced.

libstratanetsh project provides source-code to a library (formerly called libnetshclient) for use in the development of applications which require direct communication (using the netsh protocol) with a Foxmoxie Networks STRATA-family router, or any STRATA protocol-capable implementation.
This library may be used to develop client or server implementations, and has also been used for purposes ranging from file transfer to voice applications.
Enhancements:
- TLS implementation optimized, updated API, server-operation support, bugfixes
