I did a project to recognize bird sounds in the past.
Speech recognition software can be used for this task, but you need to change ASR front-end
to cope with bird sound vocalizations.
What type of birds do you want to recognize?

Hi Luis,

Thanks for the response. The project hasn't been spec'ed fully yet but I would imagine that the expectation is for the software to recognise bird calls ranging from small Warblers with high pitched chattering to Crows with their harsh squawks and everything in between. In total there will be something in the order of 600 to 700 species that need to be identified. I'm not sure yet over how many phases the project will stretch but, if I complete phase successfully I can probably position myself well to see the project through to the last phase.

Ultimately I think the idea will be that a user can record a bird call in the field, using his PDA for instance, and then have the software immediately identify the bird based on the call, or at least give a short list of most likely candidates.

I'm glad to hear that someone else has done something similar already and that you can confirm that Speech Recognition can be used for this application. I would love to hear more about the project you did.

Regards,
Déwald Swanepoel

Déwald Swanepoel,

I worked with Amazon sound birds to set up a demo for a client.
Client didn't buy project, but demo worked for 4 types of birds
with a very high accuracy.
PLP was used as a front-end, but it is necessary to change some
parameters to cope with high pitch, etc. It is an experimental
jobs to set these parameters.

Could you explain PLP perhaps please? The only PLP I know of was something like Packet Layer Protocol from way back when I did some work on X.25. Obviously you're referring to something different.

Would you mind if I contact you off list with some specific questions? You seem to have some experience of ASR and specifically bird call recognition and I'm sure you'd be able to answer most of my questions without too much effort. I'll leave you alone then Wink | ;-)

*****************************************************************

when i didnt enter any letter the output is:

count_a: 0
count_b: 0

when the letter increase the number of count display multiplies too and it shouldnt'..

like this; input words "aaa"

count_a: 0
count_b: 0
count_a: 0
count_b: 0
count_a: 1
count_b: 0
count_a: 1
count_b: 0

Where do you think is the problem on my codes?

What should be the exact output for input "aaa" ?

Have you tried "running" this on paper ? ie. do all of the operations on paper with a pencil ? follow each step manually.

Did you try debugging, i.e. stepping in the code after each getchar ?
Put a breakpoint at the switch and try following what is happening.

good luck.

Its a program for a Finite State Machine that accept a language that has 3 consecutive letters in the end.

Thats the diagram.

I've never seen an FSM that looks like this. How about something along the lines of:

void state0( void )
{
    if (buffer[pos] == 'a')
    {
        pos++;
        state1();
    }
    else if (buffer[pos] == 'b')
    {
        pos++;
        state3();
    }
}
  
void state1( void )
{
    if (buffer[pos] == 'a')
    {
        pos++;
        state2();
    }
    else if (buffer[pos] == 'b')
    {
        pos++;
        state3();
    }
}
...
void state5( void )
{
    valid = true;
}
  
void main( void )
{
    state0();
      
    if (valid)
        cout << "Valid" << endl;
    else
        cout << "Not valid" << endl;
}

There was nothing with the diagram. It was your implementation of it that I had trouble with.

Other than using cout, the code snippet I showed was plain C. No objects were used or are required.

Is it possible to create a driver as an ActiveX control/component in VC++ or even in .Net? If so, how can it be done? Thanks in advance.

What do you mean "driver"? If it is a file like "*.sys". Then I think it is impossible. They are totally different concepts.

I apologize for not being more specific. I was thinking more along the lines of creating an interface that inherited classes/variables/properties from the ddk. I hope I described it better. Thanks in advance

Hello,
I am facing a problem with registry key. I have a MFC singledoc application with three splitters and lots of views. My registry key was set in InitInstance function by SetRegistryKey(_T("Local AppWizard-Generated Applications")). Everything works fine till the moment I try to change the string parameter in SetRegistryKey() function. When I change it I recieve many strange error during initialization and opening new document. Can you tell me what is going on? Thanks Tomas

BOOT Failure error

Hi,
I have a VC++ desktop application. It is an SDI application with some HTML views.
When I close the application and re-start the machine I m facing
BOOT FAILURE error. Then I give load the BOOT CD and select repair it things will work fine.

This is not replicable, but happens rarely that too in few machines.

When I turn on UAC and run my application with Standard Priviledge things are working fine.

System Event logs does not provide any clue.

Boot logs(ntbtlog) from system dir also didn't help.

How do I proceed?

Any help to resolve this.

Regards,
Karthik.

I suspect, your application is playing around with the system files.
That is why when you run with standard privileges, the application fails to do its stuff and everything is OK.
