As pointed out by you, actxserver function has to be used to read speaker notes for each slide in PowerPoint from MATLAB and collect them as a string/text. You can use the following steps:
Create an ActiveX object for PowerPoint using the actxserver function in MATLAB.
ppt = actxserver('PowerPoint.Application');
Open the PowerPoint presentation using the ppt.Presentations.Open method.
presentation = ppt.Presentations.Open('path/to/presentation.pptx');
Make sure to replace 'path/to/presentation.pptx' with the actual path to your PowerPoint presentation.
Loop through each slide in the presentation and extract the speaker notes using the Slide.NotesPage.Shapes.Placeholders.Item property.
notes = cell(1, presentation.Slides.Count);
for i = 1:presentation.Slides.Count
notes{i} = presentation.Slides.Item(i).NotesPage.Shapes.Placeholders.Item(2).TextFrame.TextRange.Text;
end
Close the presentation and quit PowerPoint using the presentation.Close and ppt.Quit methods.
presentation.Close;
ppt.Quit;
Concatenate the speaker notes for all slides into a single string using the strjoin function.
allNotes = strjoin(notes);
This code creates a single string allNotes that concatenates the speaker notes for all slides in the presentation, using the strjoin function.
