UPDATED ANSWER

I've reproduced this issue when userPrompt has two strings, e.g.) text area contains line breaks.

You might add join command to combine multiple lines into one string array.

userPrompt = app.whatdoyouwanttosayTextArea.Value;
userPrompt = string(userPrompt);
userPrompt = join(userPrompt); % combine multiple lines in to one string array 
NET.addAssembly('System.Speech');
speak = System.Speech.Synthesis.SpeechSynthesizer;
speak.Volume = 100;
Speak(speak, userPrompt);

ORIGINAL ANSWER

Are you using another .NET or Java library which also uses Speak function?

How about the following?

speak.Speak(userPrompt);

thank you for your answer

i am still getting the same error

it seems whatdoyouwanttosaytextarea.value can not be converted to a string to match the signature, what do you think

[Kojiro Saito]

I understood. Could you tell us your MATLAB version? I've tested your code in R2020b and R2021a but works without an error.

r2020b

[Kojiro Saito]

All right. Could you place a breakpoint on line NET.addAssembly('System.Speech'); and check the userPrompt variable is exactly a string type?

[michael olagunju]

not sure i am doing this right

[Kojiro Saito]

Looks good to me. Could you mousehover the userPrompt in line 17 and confirm the data type?

For example,

[michael olagunju]

okay i right clicked on it and set the condition userPrompt == string

and it stops on the line when i click continue then it gives me that same error

[michael olagunju]

actually it is a 2 by 1 string array, does it have to be 1 by 1

[michael olagunju]

it worked, yes its supposed to be a 1by 1 array

[michael olagunju]

thank you for your help, i learnt how to insert a conditional breakpoint too :)

[Kojiro Saito]

All right, I understand this issue occurs when the TextArea contains multiple lines. I've updated my answer.
