 uSpeech library
 ==============
-
+This  is branch is the 3.0 release sandbox. It is currently vaporware unless you wish to contribute.
 The uSpeech library provides an interface for voice recognition using the Arduino. It currently produces phonemes, often the library will produce junk phonemes. Please bare with it for the time being. A noise removal function is underway.
 ##Minimum Requirements ##
 The library is quite intensive on the processor. Each sample collection takes about 3.2 milliseconds so pay close attention to the time. The library has been tested on the Arduino Uno (ATMega32). Each signal object uses up 160bytes. No real time scheduler should be used with this.
