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:
https://www.mathworks.com/matlabcentral/fileexchange/65266-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 =
0.9385
Please refer to the html folder in the submission for a step-by-step getting started guide.
Thanks,
Gabriele.

Hello, I want to do a project for arabic speech to text conversion using matlab. Can I use wav2vec?

As of R2023b, all pre-trained speech-to-text models available with MATLAB via Audio Toolbox (including wav2vec) only support the English language.
For different languages, including Arabic, you want to use one of the cloud services supported by speech2text. Please remember that this workflow requires first creating an account with one of 4 supported services (Amazon Transcribe™ is also part of the mix since R2022b) and then downloading a credentials files onto a local folder on your MATLAB path. You can refer to the accompanying examples of speech2text for the details.
For Arabic specifically, you want to ensure you read the documentation of the service of your choice and identify the language localization most closely related to the content you need to transcribe.

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)
return;
end; % Bail out if they clicked Cancel.
caUserInput = char(caUserInput); % Convert from cell to string.
NET.addAssembly('System.Speech');
obj = System.Speech.Synthesis.SpeechSynthesizer;
obj.Volume = 100;
Speak(obj, caUserInput);
Speech to text is a lot more complicated of course.

Hi, is there any possibility to function STT without an internet connection?
