I have a simple code with function "detectspeech" (see button) but in my pc app (version R2023a) don't work (in online version yes), give me this error:

error:

"Error using gather

Too many input arguments.

Error in detectSpeech (line 88)

[fs,varargin{:}] = gather(fs,varargin{:});

Error in teste_detetar_fala (line 18)

detectSpeech(audioIn,fs,"Window",win,"OverlapLength",overlap,"MergeDistance",mergeDist)"

Anyone know to solve this problem or why this hapenning?

code:

[audioIn,fs]=audioread('Sujeito_Teste.wav');
windowDuration = 0.074; % seconds
numWindowSamples = round(windowDuration*fs);
win = hamming(numWindowSamples,'periodic');
percentOverlap = 35;
overlap = round(numWindowSamples*percentOverlap/100);
mergeDuration = 0.44;
mergeDist = round(mergeDuration*fs);
detectSpeech(audioIn,fs,"Window",win,"OverlapLength",overlap,"MergeDistance",mergeDist)

Thanks for your attention.

It looks like a bug in the detectSpeech code for R2023a if you call detectSpeech with more than one parameter.

That section of the code was reworked a fair bit for R2023b beta

In version 2023b already works correctly.

Thank you all very much.

Hi Felipe ,

I understand that you are facing an error while running a code in MATLAB App which runs fine in MATLAB online .

It is happening because MATLAB online has all packages preinstalled in cloud .Since , you are using 'audioread ' function you will need to install the neccesary toolboxes like 'Audio System Toolbox' and 'Signal Processing Toolbox' before using it.

Follow the given steps to install the toolbox :

Open MATLAB App.
Click in Add-Ons
Select Get Add-Ons
Install the required toolbox

Refer to the this given documentation for details : https://in.mathworks.com/help/audio/ref/detectspeech.html

When I run it on my computer, it says

'detectSpeech' requires Audio Toolbox.

Error in test1 (line 17)

detectSpeech(audioIn,fs,"Window",win,"OverlapLength",overlap,"MergeDistance",mergeDist)

so you need the "Audio Toolbox". The online version of MATLAB will have that toolbox while your local computer installation does not. Use the Add-ons button on the Home tab of the tool ribbon to get that toolbox.
