CROSSFADE SOUND AS 3.0 - actionscript-3

Question

I'm an AS 3.0 project where I'm getting into an array sounds to compose a particular set of phrases. The problem is that it sounds too much shock and wanted to make a crossfade effect to better attach a word to each other.
My problem is that I can not join them because every sound played one after another, is there any way to merge that can reach the end of a sound with the beginning of the next?
Thank you very much.
The code I'm working with is something like this:
for (iii = 0; iii < numpalabras; iii ++)
{
if (abuscar2 = abuscarArray[iii])
{
vocaliza(abuscar2, iii);
}
}
iii = 0;
localSound = lossonidosArray[iii];
var soundTrans:SoundTransform = new SoundTransform;
soundTrans=SoundMixer.soundTransform;
soundTrans.volume=1;
soundTrans.pan=0;
elcanal.soundTransform = soundTrans;
elcanal = localSound.play(85, 0, soundTrans);
elcanal.addEventListener(Event.SOUND_COMPLETE, locutapalabra);
}
function locutapalabra(event:Event)
{
if (iii < (ii))
{
iii=iii+1;
localSound = lossonidosArray[iii];
var soundTrans:SoundTransform = new SoundTransform;
soundTrans=SoundMixer.soundTransform;
soundTrans.volume=1;
soundTrans.pan=0;
elcanal.soundTransform = soundTrans;
elcanal = localSound.play(85, 0, soundTrans);
elcanal.addEventListener(Event.SOUND_COMPLETE, locutapalabra);
}
function vocaliza(abuscar2, iii)
{
if (datosXML.palabras.(palabra == abuscar2).palabra == abuscar2)
{
ii++;
elfic = "mp3/" + datosXML.palabras.(palabra == abuscar2).fichero;
var elsonido :Sound = new Sound();
elsonido.addEventListener(IOErrorEvent.IO_ERROR, errorprogreso);
var laurl:URLRequest = new URLRequest(elfic);
elsonido.load(laurl);
lossonidosArray[ii] = elsonido;
}
}
I am new to AS 3.0 programming and I do not get clear my code to make the words come together with each other, because I get to build such phrases of several words.
Thank you very much.

Answer 1

For cross-fading, you can use a tween library (like greensock) to tween the volume of the sound channel:
var sound:Sound = new Sound(...);
// start volume at 0
var soundChannel = sound.play(0, 0, new SoundTransform(0));
// tween volume to 1
TweenMax.to(soundChannel, 1, { volume: 1 } );
// half a second before the sound is complete, tween volume to 0
TweenMax.to(soundChannel, .5, {volume: 0, delay:(sound.length/1000)-.5});

Answer 2

var timer:Timer = new Timer(3000) //set to how long to wait
timer.addEventListener(TimerEvent.TIMER, nextSound);
function nextSound(e:Event):void
{
listenForNextSound(); //this is where you play your next sound
}
timer is a timer variable, and when 3 seconds pass (or however long you want) the next sound will start playing.
To make your timer variable a bit more accurate, you can make it the duration of the sound by listening for the COMPLETE Event:
yourTimer.addEventListener(Event.COMPLETE, function() {
timer.delay = yourTimer.length - howMuchTimeBefore;
});
