Project: Speech controlled power supply and signal generator

Hi fellow electronics people, i'm a student and am working on my thesis project which is what the title said. using speech control on a power supply AND a signal/function gen.
I have a basic idea on what to do which is to interface a speech recognition module(w/c is not part of my design) into a MCU that can control the P.S. and signals gen. thats my idea so far, i need help on the following things
1. what mcu to use?
2. a little idea on how i can make the mcu control the P.S and S.G.
3. what S.G. to use (op-amp based / DSP based)
4. any help regarding this because i really have no idea how to come up with my project i'm still working on the early stages of it which is reviewing related lit.

thanks in advance, any help would greatly be accepted
(i forgot to mention that the amplitude are limited only to a 5 values of volts and exact increments for both the PS and SG, the frequency for the SG is also limited to 3 values of frequency 500,1k and 2k)

 

the output would be binary codes, tho i have to still train the module to output the exact binary codes for the exact words
is this what you meant?
thanks Mr. Ken

 

oohh so it depends on the spec. let me check what module would be available and ill bump this topic
thanks again btw Mr. Ken

 

Hi so after analyzing, we would be using this speech module since its the one that is readily available in our place and cheap (in comparison with others)
HM2007

i think its a 48pin

 

the module would output binary digits, which i will input to the mcu right?
dont know much about data configuration tho ive searched i think it would be
fetched now and then, used for many times

 

im confused, i'm using the speech module to react to cammands to control a power supply and a function gen. i dont know much and i dont know what mcu to use. argh
*completely clueless* sorry for being like this

 

yea maybe, but this is a final requirement project. tho we are working with some basic project like mcu based railway system and pc based tank refiling system which we are doing at the same time with this speech rec project

 

well, i figured out how to control the supply by using transistor switches for the ratio in the load to be read at the output, tho i still have no idea haw about the signal gen.

frankly, i never had to program with a mcu since the one we used before was in a robo kit. but one of my friends used fpga in the speech rec project.

he also said to ask wether its better and easier to use microprocessor like 8086 or just mcu's ?

 

another friend suggested zilog and i'm weighing them in their advantages and appropriate-ness now
