Speex is a patent-free audio compression format designed for speech and also a free software speech codec that may be used on VoIP applications and podcasts. It is based on the CELP speech coding algorithm. Speex claims to be free of any patent restrictions and is licensed under the revised (3-clause) BSD license. It may be used with the Ogg container format or directly transmitted over UDP/RTP.
The Speex designers see their project as complementary to the Vorbis general-purpose audio compression project.
Speex is a lossy format, meaning quality is permanently degraded to reduce file size.
The Speex project was created on February 13, 2002. The first development versions of Speex were released under LGPL license, but as of version 1.0 beta 1, Speex is released under Xiph's version of the (revised) BSD license. Speex 1.0 was announced on March 24, 2003, after a year of development. The last stable version of Speex encoder and decoder is 1.1.12.
Unlike many other speech codecs, Speex is not targeted at cellular telephony but rather at Voice over IP (VoIP) and file-based compression. The design goals have been to make a codec that would be optimized for high quality speech and low bit rate. To achieve this the codec uses multiple bit rates, and supports ultra-wideband (32 kHz sampling rate), wideband (16 kHz sampling rate) and narrowband (telephone quality, 8 kHz sampling rate). Since Speex was designed for Voice over IP (VoIP) instead of cell phone use, the codec must be robust to lost packets, but not to corrupted ones. All this led to the choice of Code Excited Linear Prediction (CELP) as the encoding technique to use for Speex. One of the main reasons is that CELP has long proven that it could do the job and scale well to both low bit rates (as evidenced by DoD CELP @ 4.8 kbit/s) and high bit rates (as with G.728 @ 16 kbit/s). The main characteristics can be summarized as follows:
Spooks Is on some other script
That's why you be lovin' It
My crew that's the butter clique be glad you discovered It
Hip hop originals spook rock we runnin' this

Spooks still spit It for you thugs yeah we done that
You want It then battle a spook we can't lose for god we fight
Suffice the plight with the might from piety rights
Plunge you with lice plead your plight spice for spite
On judgement night with three strikes
The wicked Is right livin' In trife recite songs
Repent crimes It's pendulum time
The comin' of christ for mankind

Most of these stupid Mc's could never handle the steez
Spooks be bringin' when we singin' man y'all wing It and please
I got the crucial chromosones to stimulate these microphones
The hardware plus the software plus the hormones
A prerequisite for wreckin' cliques keepin' It hectic
Phenobarbitol could never stall this wild epileptic style
Electric and mental spasmodic erotic
Type of flow that could only be described as hypnotic
Man It's a fact that I got It hemmed up and guaranteed
Mc's approach me but they gainin' In the cranial bleed
You need to learn to read between the lines of coke dust and weed
You're smokin' chokin' off the speed of Illusion Indeed

I speak the spookanese
Like abominable dominos crushin' crews with ease
Who never had the need or the beats the loser's theme
Oh what I'm always luke warm
Then put that group on and wham your necks under the Yukon
I crash the savage talkin' badly while livin' lavish
Put your cabbage on the block chop straight drop the hatchet
Now your head's rollin'
Put my fingers In your eyes and my thumb In your mouth
And make up a new sport called head bowlin'
Oh Is flow In It boy you're finished
Bite my script and I'll extort my percentage
Of your royalty not waitin' to disregard It's blatant
When chhh chhh ahhh ahhh I sneak up like Jason
So got me when ya can't get It bitin' me's a grand mimic
This Is from Popeye but even he gon' eat some bad Spinach
Cause I'm forever spittin' for cheddar fixin's
Make clever kittens do the wop outside the reverend's mission
