how to make speech recognition

[Hymae]

I will make a speech recognition system the which can
Recognize vowels (A, I, U, E, O), using a backpropagation
neural network system.
I use the components IntelligenceLab 5.0.1 for Delphi, AudioLab 5.0.1 for Delphi and I am using Delphi XE2 program.

I encounter problems when applying it, I use Openwire Editor and
components that I use:
1. ALAudio1 (to take sound from a microphone)
2. ALSpectrum1 (spectrum components)
3. ILNeuralNetworkBackpropTrain1 (backprop training algorithm components)
4. ILNeuralNetwork1 (neural network clasifier)

to the output pins of the component spectrum can I connect with the
input of clasifier neuralnetwork1, but I can not connect the output
spectrum with component input ILNeuralNetworkBackpropTrain1.
My question whether the steps that I am doing is correct or whether
there is still a mistake? or need additional program listings?

greetings Hymae
