Hi Nemala,
I work at MathWorks and I noticed this old question of yours just now. In case it was useful to others, I thought I'd leave a link to our recent MATLAB Central sumbission speech2text:
That enables to leverage 3rd party speech-to-text web services (so far including from Google, Microsoft and IBM) directly from MATLAB using a simple MATLAB Function. The syntax looks like the following:
>> [samples, fs] = audioread('helloaudioPD.wav');
>> soundsc(samples, fs)
>> speechObject = speechClient('Google','languageCode','en-US');
>> outInfo = speech2text(speechObject, samples, fs);
>> outInfo.TRANSCRIPT =
ans =
'hello audio product Developers'
>> outInfo.CONFIDENCE =
ans =
Please refer to the html folder in the submission for a step-by-step getting started guide.

I have downloaded the latest version of speech2text in Matlab2018a.
When I am trying to run I am getting the following error:
Output argument "tableOut" (and maybe others) not assigned during call to
Error in speech2text (line 45)
tableOut = connection.speechToText(y,fs,timeOut)
Error in stt (line 7)
outInfo = speech2text(speechObject,samples,fs,'HTTPTimeOut',25)
Immediate help is appreciated.

Is there a way to use this speech2text program offline without connecting to the Internet?
Also, how can we add a new language package to this program?

Not an answer for you, but in case anyone is interested in the reverse direction (text to speech).....If you have Windows, try .Net. Try this MATLAB code snippet:
% Program to do text to speech.
% Get user's sentence
userPrompt = 'What do you want the computer to say?';
titleBar = 'Text to Speech';
defaultString = 'Hello World! MATLAB is an awesome program!';
caUserInput = inputdlg(userPrompt, titleBar, 1, {defaultString});
if isempty(caUserInput)
end; % Bail out if they clicked Cancel.
caUserInput = char(caUserInput); % Convert from cell to string.
obj = System.Speech.Synthesis.SpeechSynthesizer;
obj.Volume = 100;
Speak(obj, caUserInput);
Speech to text is a lot more complicated of course.

Did you overlook Gabriele's answer above? Does that not help? Exactly what kind of code were you looking for? What is the topic of your thesis?
