Did you try an internet search? There are lots of discussions about this topic. Maybe this would be good starting place:

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.

How can I create speechClient object ? I got stuck in this point. Thank you

[Gabriele Bunkheila]

Hello,

The property-value pairs for speechClient vary depending on the specific service used (i.e. Google, IBM, Microsoft). You should find it useful to take a look at the "Create speechClient" section of the "Examples" tab of the submission page for speech2text - that also include links to the documentation of the respective services.

I hope this helps.

Gabriele.

Ichecked thta section and run this line to the command window;

speechObject = speechClient('Google','languageCode','en-US')

but it gave me an error 'Size and validator functions not supported for abstract properties.

Property 'Name' is abstract in class 'BaseSpeechClient'.

'

but I cannot open BaseSpeechClient or any other .p files because of the protection. Do I use wrong speechClient line?

Hello,

Your error stack looks like you hit a bug in speech2text code seen in MATLAB releases older than R2018b.

I have fixed the bug in the speech2text submission and verified that it works in MATLAB releases R2017a through R2018b. Please download the latest version of speech2text and try again.

Thanks,

Raja

Thank you so much it works so well

Hello

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

"BaseSpeechClient/speechToText".

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)
  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.

please send me the code to my gmail [e-mail]. It will be great help for my thesis. I'm never forget your kindness.

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?
