Voice Recognition Implementation

@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.

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?

mrjj

First you get it to build then
use in Qt. its in 2 steps.
You really MUST read docs slow and carefully ,
else u miss a step and it wont work.

So first step is to get it to build using the tuts.

Naveen_D

@mrjj what ever now i have installed pocketsphinx...can i use it in qt o not that em not clear ? anyhow its external lib rite i can use the .so file of pocketsphinx ?

Naveen_D

@mrjj any links where i can get the tut regarding this to get it build ??

mrjj

The tut you found seemed good?
http://jrmeyer.github.io/installation/2016/01/09/Installing-CMU-Sphinx-on-Ubuntu.html

So if you have build the so files you are to use them
This part mostly fails due to paths so make sure u check.

You can open .pro file then, in open file, right click and select
Add library. Fill it out and make sure!! its correct.
Linux lib, shared etc.

http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

Then you should be able to link against it.

Same story with pocket

http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

also MAKE 100% sure you did as it says

"Prerequisites

You must have SphinxBase, which you can download from http://cmusphinx.sourceforge.net. Download and unpack it to the same parent directory as PocketSphinx, so that the configure script and project files can find it. On Windows, you will need to rename 'sphinxbase-X.Y' (where X.Y is the SphinxBase version number) to simply 'sphinxbase' for this to work."

@mrjj i want to attach the screen shot of what files i have got after running the steps in that link http://jrmeyer.github.io/installation/2016/01/09/Installing-CMU-Sphinx-on-Ubuntu.html for both sphinxbase and pocketsphinx but i qm not able to do that...how can we attach the screen shots here ???
