How can I get my code to speak with a voice

Im working on a big program and one of the few things I want it to do is speak. Does anyone have an idea. For example if my code is:

   x=input('Hello','s');

if strcmpi(x,'Hello')
  fprintf('Hello sir')
end

I want the hello sir to come out with a voice.

[Sylvain KPEKOU]

defaultString = 'Hello Sir';

NET.addAssembly('System.Speech');

obj = System.Speech.Synthesis.SpeechSynthesizer;

obj.Volume = 100;

Speak(obj, defaultString );

Yes, that SpeechSynthesizer answer was already given below. Perhaps you didn't scroll down to the answers section to see it.

How can i store the speech in a variable and produce audio output in raspberry pi 3

For text to speech, if you have Windows, you can try my demo program:

% 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);

Wow that is amazing is there a way where I can change the voice from male to female.

[Rainaire Hansford]

also I have a code like this where if I type in a input it will respond with an out put for example:

 x=input('Password','s');
if strcmpi(password,'hello')
fprintf('Password accepted.')
end

I want say "Password" and when I type in or speak it "hello" i want it say "password accepted". Do you have any idea how to get that to happen?

[Walter Roberson]

You can use the SelectVoice method to choose a different voice.

To have it output 'Password accepted.', use

Speak(obj, 'Password accepted.')

To be able to speak "hello" and have it understood, then you need some completely different software: you would need speech recognition software. There are some a number of postings about that, and there are some contributions such as https://www.mathworks.com/matlabcentral/fileexchange/27276-speech-recognition or https://www.mathworks.com/matlabcentral/fileexchange/36398-speech-recognition-using-mfcc-and-lpc

Hey Walter sorry its been a long time. I tried to make code above work. but it didn't seem recognize the code

speak(obj,'password accepted')

I tired:

obj=input('hello');
speak(obj,'password accepted')

So im not sure how I should go about this

[Walter Roberson]

NET.addAssembly('System.Speech');
obj = System.Speech.Synthesis.SpeechSynthesizer;
obj.Volume = 100;
speak(obj, 'password accepted')

[Edwin Cortez]

Awesome. The Speak() function worked. Thank you.

@Edwin Cortez can I see your code please

[Image Analyst]

@kim my Answer and several of the comments below it have code in them. Did you overlook the code? It's there.

There is nothing built-in. Try downloading these:

https://www.mathworks.com/matlabcentral/fileexchange?term=tts

Note that some rely on third-party apps or objects, and might only work on some versions of MATLAB. I know that at least some of them work, because I remember playing with them a year or two ago.

[Rainaire Hansford]

Are theses like add-on for Matlab?

[Walter Roberson]

The File Exchange contains MATLAB code (and possibly C or C++ code) that has been written by volunteers and made available for general use.

Some of the contributions for Text To Speech also need additional software packages beyond that.

With FEX: tts you can download different voices e.g. at:
