/*
 * 1K JavaScript Speech Synthesizer
 *
 * This is a simple formant based speech synthesizer in less than 1K of JavaScript.
 * Synthesizes speech as you type, and whole sentences upon pressing ENTER.
 *
 * The folllowing sounds/phonemes are supported:
 *
 * a,b,d,e,E,f,g,h,i,j,k,l,m,n,o,p,r,s,S,T,t,u,v,w,z,Z
 *
 * Hope you like this entry for JS1K#4
 *
 * Based on Tiny Speech Synth by Stepanov Andrey - http://www.pouet.net/prod.php?which=50530
 * Optimized and minified manually, by yours truly, @p01 - http://www.p01.org/releases/
 * Compressed using First Crush by @tpdown - http://js1k.com/2012-love/demo/1189
 *
 * To go under 1K, I had to limit the synthesizer to two formant filters using either a sawtooth or noise and discard plosive sounds. In other words I had to sacrifice quality a bit.
