Voice recognition project using RSC364

[baddman]

Hi,
I am currently doing my final year project about voice recognition security system using RSC364. Actually I'm intended to use HM2007 but I saw a post here said that the shipping cost is too much for shipping it to my country.

I would like to ask someone knows about RSC364, do I need to pre-programme into the ROM of this chip? Does it require assembly programming to make this chip functions?

Thank you.

Hi there,

I am also doing the same project based on voice recogntion security system for door opener.

So what these ppl suggest me to write a code in C or VB for the speech recogniton and perform the related task. So like if u could elaborate me more about ur project then may be we can help each other

Hi, Emantra

I am designing and constructing a voice recognition security system to light up LED. If it works, probably I will improve the system to open a door, output voice to speaker etc. This is a stand-alone system and it is not interfacing with a computer. So, I think I would not need to write code in C or VB.

I hope that we can help each other about our project too. So, can you elaborate more about your project?

I am doing a project on speech recognition using the microcontroller which then has to open or close the door.
but the problem that i am facing is that i am pretty new in this field.

so here is what my speech recognition ckt has to do
1. maintain a database of 2 or 3 person sound of two command OPEN and CLOSE.
2. when the authorized person speaks on the mic saying OPEN or CLOSE has to turn on the DC motor.
3. if an unauthorized person speaks to the mic then generate a buzz sound.

when these task were performed by the microcontroller then it has to dirive a DC motor in order to open or close the door. for this purpose i have thought to use the H-bridge.

and also i got this site which contains and 8051 like microcontroller that works with in-built speech recognition technique. so i hope that this might work.

here is the link: www.sensoryinc.com

and also i am posting a h-bridge figure for u to be more clear.

An H-bridge is rather complicted for such a simple task, why not just use a DPDT relay?.

 

[Emantra]

What is this DPDT relay? And how does this work?

If u could explain these to me, then I'll be very thankful.

DPDT is "Douple Pole Double Throw", two changeover switches controlled by a solenoid - it's a VERY common relay, and you can use it to reverse a motor.

As you're opening and closing a door, presumably you have "limit switches" to stop the motor when it's fully open or closed?. Because of this a DPDT relay, protection diode across it, a driver transistor, and a base feed resistor are all that you need to open and close the door.

 

[Emantra]

Can u provide me with the schematic coz I think that, that will clear me little more coz I'm pretty confused about what you are saying


thanks

hello heathtech,

I was unable to view 7195A_big.jpg.

Can u again post it.

Thanks

 

[heathtech]

Maybe you can look at it here.

In the circuit of the H_bridge posted by Emantra, can u guys help?

What is the use of the Q1 and Q2 transister?

Can't we just input the signal to the Q3-Q4 and Q5-Q6?

I too working on the same project can u plz help me

 

[fijrinroysh]

My location is Tamilnadu ,India......can you suggest me a place where i can get the RSC364 kit easily...........and help me with the price....

8051 based speech recognition

hi,
I don't know much about using RSC364.
I want to design speech recognition using 8051 mic.
can anyone provide me any information regarding this.
how feature extraction is carried out?
Whether it is possible to implement an HMM and Viterbi algorithm in Microcontroller is possible?

If anyone could explain these to me, then I'll be very thankful.

hi,
I'm currently doing a project in Voice Detection in Telephony using IVR(interactive voice response)... we are basically concentrating on human voice detection..
Can anyone suggest recent applications on voice detection & recognition...

Thats frightening, to be able to code a speech recognition system and not know what a DPDT relay is, times have changed.
