Voice Recognition Implementation

@Naveen_D
If you mean the pocketsphinx-master.zip , its the source code.

On windows, you will use the pocketsphinx.sln to compile.
Then you get DLLS etc. ( the resulting library)

There seems to be no precompiled binaries so its up to you to make them.

Note. you must compile both on windows and linux. You cannot
use libs from windows in linux and reverse.

@mrjj that means i should run the complete source code in qt creator and build the binary and use the required libraries ???

[Naveen_D]

@mrjj for linux also i need to use pocketsphinx.sln ?

[mrjj]

@Naveen_D
Yes, first step is to get it to compile. Either in Creator or in Visual Studio .
That will produce DLL/LIB file.

Then you will make new project ( your project) and add this DLL/LIB to it.

• linux also i need to use pocketsphinx.sln ?
  No. for linux , there is other build instructions.
  $ ./autogen.sh
  $ ./configure
  $ make clean all
  $ make check
  $ sudo make install
  --
  SLN files are for visual studio.

There is no visual studio on linux.

@mrjj Okay thanks...i wanted to know is it possible to develop an desktop app using this which accepts voice recognition? or we need a pos device with some microphone?

[mrjj]

Well the pc or device
must have soundcard and a microphone but other than that,
there should be nothing stopping you to run as a Desktop app.

I used this on pc

Its brilliant.

@mrjj ya but nuance is not open source rite so em trying with pocketsphinx

[mrjj]

@Naveen_D
Oh, no. its as commercial as it gets.

it was as example of voice Recognition on the desktop :)

The best i ever tried. It worked flawless even when multiple people speaking!

They even do allow others to use
http://www.nuance.com/for-developers/dragon/index.htm
but its not open source or gratis.

So i just mentioned it for a sample of VR that truly works :)

[Naveen_D]

@mrjj Is there any algorithm for voice recognition that i can use ?

[jsulm]

@Naveen_D Yes, pocketsphinx for example which @mrjj already suggested. Or do you want to implement it by yourself?

[Naveen_D]

@jsulm no i will use pocketsphinx only

Hi,

Just in case, there's a speech recognition branch in the QtSpeech module that's current work in progress but might be interesting for you.

[Naveen_D]

Hello everyone

my question is do I need to install CMU-SPHINX first and then pocketsphinx ? or there is any other way for installing pocketsphinx in ubuntu?

[mrjj]

Hi
You can try this

@mrjj i have installed cmu-sphinx and pocketsphinx using the instructions given in this link http://jrmeyer.github.io/installation/2016/01/09/Installing-CMU-Sphinx-on-Ubuntu.html is it correct ?

If yes, where i will get the lib of this and how to use this lib to make use of voice recognition ?

[mrjj]

@Naveen_D
It seems like a good tut.

When you compile you will get the lib
and this lib you will use in the real project.

[Naveen_D]

@mrjj In qt creator i need to compile?

one more question, since i am new i want know what this sudo make install will do ?

[mrjj]

Im not sure if it comes with a .pro file?
Its should be clear from build instructions what to do
on each platform.

sudo make install
That will copy the "result" (exe, .a ) to a place so its installed.

[mrjj]

@mrjj

The tut you found is not Qt related so its with normal linux toolchain
for CMU-Sphinx.

He starts with
"When I installed SPHINX for the first time in September 2015, it was not a fun experience."

So be prepared to really read what he does and read docs for it. its not trivial to build.

[Naveen_D]

@mrjj I am totally confused regarding this, what i need to do for pocketsphinx so that i can use it in qt for voice recognition in ubuntu?
