Speech to midi converter?

I tried it, and it sounds quite good, but not quite like this: https://www.youtube.com/watch?v=muCPjK4nGY4

any other ideas? I tried mapping the amplitude as well, and make a threshold for it to send notes to my electric piano:

(
{
	var buf = Buffer.alloc(s, 2048, bufnum:2);
	var sig = PlayBuf.ar(2, 1, loop:1);
	var analysis = Pitch.kr(sig, minFreq:18.midicps, maxFreq:108.midicps, ampThreshold:0.001);
	var amp_anal = Amplitude.kr(sig);
	SendReply.kr(Impulse.kr(50), "/anal", [analysis[0][0], amp_anal[0]]);
	/*var chain = FFT(buf, sig);
	var trig = Impulse.kr(30);
	chain[0].pvcalc(80, {
		|phas, mag|
		SendReply.kr(trig, "/anal", mag);
	});*/
}.play
)

(
OSCdef.new(\midiConverter, {
	|msg|
	msg.postln;
	if(msg[4] > 0.01, {
		~pno.noteOn(0, msg[3].cpsmidi.asInt, msg[4].linlin(0,1,60,127));
		~pno.noteOff(0, msg[3].cpsmidi.asInt,60);
	});
}, "/anal");
)
