Speech recognizer circuit

[ekozo]

how to start my project for speech recognizer. Do you have any idea or schematic.

Basically a UC with FPU ALU and a built-in A/D module.
Externally to the core, a Microphone circuit.

ekoso,


The first question was conceptually answered, once was the required Hardware to speech recognizer.
Concerning to Firmware/Software requirements, it is a quite complex area, and is also subjected to behavioral input data, and the set of terms to be recognized : ( numbers and letters ? Words ? )

The classical approach is to use a Neural Network concept.
