eSpeak is a compact open source Linux and Windows speech synthesizer for English and other languages. eSpeak uses a “formant synthesis” method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings.
eSpeak is available as:
A command line program (Linux and Windows) to speak text from a file or from stdin.
A shared library version for use by other programs. (On Windows this is a DLL).
A SAPI5 version for Windows, so it can be used with screen-readers and other programs that support the Windows SAPI5 interface.
eSpeak has been ported to other platforms, including Android, Mac OSX and Solaris.

DFasma is free open-source software which is used to compare audio files in time and frequency. The comparison is first visual, using waveforms and spectra. It is also possible to listen to time-frequency segments in order to allow perceptual comparison. It is basically dedicated to analysis. Even though there are basic functionalities to align the signals in time and amplitude, this software does not aim to be an audio editor.
Features:
Can load about 25 different audio formats (thanks to libsndfile or libsox).
Shows spectrogram, amplitude, phase spectra and group delay.
Can play a filtered sound given a selected frequency band.
Rectification of the spectrogram tilt (cepstral lifting).
Can create and edit segmentation files.
Can create and edit fundamental frequency (F0) files (thanks to REAPER).
Meson Player is a very convenient music player if you don’t need a GUI to control playback or manage playlists. You just run it and then forget about it. The player runs in the background. Switching tracks, volume control, loading and saving playlists, all of this is performed by using hotkeys, therefore you can control the player while working in any application.
Meson Player supports gapless playback, Last.FM, a lot of music file formats (stream and tracker), Internet radio and playlist management.

Listen to CD’s or stream music from the Internet. Tweak the sound with the graphical equalizer or experiment with LADSPA effects.

Quod Libet is a GTK+-based audio player written in Python, using the Mutagen tagging library. It’s designed around the idea that you know how to organize your music better than we do. It lets you make playlists based on regular expressions (don’t worry, regular searches work too). It lets you display and edit any tags you want in the file, for all the file formats it supports.
Unlike some, Quod Libet will scale to libraries with tens of thousands of songs. It also supports most of the features you’d expect from a modern media player: Unicode support, advanced tag editing, ReplayGain, podcasts & Internet radio, album art support and all major audio formats – see the screenshots.
Ex Falso is a program that uses the same tag editing backend as Quod Libet, but isn’t connected to an audio player. If you’re perfectly happy with your favorite player and just want something that can handle tagging, Ex Falso is for you.
LAME is used to encode / compress audio data into the lossy MP3 file format. It’s a high quality MPEG Audio Layer III (MP3) encoder, licensed under the LGPL.
