I have made a code which runs on matlab online but shows an error when run on my local pc

% Parameters for recording
fs = 44100; % Sampling frequency (Hz)
nBits = 16; % Bit depth
nChannels = 1; % Number of channels (1 for mono, 2 for stereo)
duration = 10; % Duration of the recording in seconds

% Create an audiorecorder object
recObj = audiorecorder(fs, nBits, nChannels);

No audio input device found on this system.

% Display message
disp('Recording will start in 3 seconds...');
pause(3); % Wait 3 seconds before starting
disp('Recording now...');

% Start recording
recordblocking(recObj, duration);
disp('Recording completed.');

% Retrieve audio data
audioData = getaudiodata(recObj);

% Save the recorded audio as a .wav file
audiowrite('speech_dft.wav', audioData, fs);

disp('Audio file saved as "speech_dft.wav".');

[y,fs] = audioread("speech_dft.wav"); 
sound(y,fs)
transcript = speech2text(y,fs)

% Assuming 'transcript' contains the transcribed text
transcript = lower(transcript); % Convert to lowercase to handle case-insensitivity

% Initialize variable x
x = NaN; % Default value (if neither word is found)

% Check if "height" is in the transcript
if contains(transcript, 'height')
    x = 1;  % Assign 1 if "height" is found
% Check if "travel" is in the transcript
elseif contains(transcript, 'travel')
    x = 0;  % Assign 0 if "travel" is found
end

% Display the value of x
disp(['Value of x: ', num2str(x)]);

Hi @Anurag

Could you please provide the error message you encounter when running the code on your local PC?

Error in speech2text

[Walter Roberson]

In R2023b the syntax is

transcript = speech2text(clientObj,audioIn,fs)

where clientObj is returned by speechClient()

Answer 1

[Walter Roberson]

In R2022b, R2023a, and R2023b, https://www.mathworks.com/help/releases/R2023b/audio/ref/speech2text.html has a different calling sequence.

The calling sequence changed as of R2024a.

Answer 2

Hi Anurag,

I also encountered a similar error while running the code snippet in MATLAB R2023b.

The problem arises due to the version mismatch between MATLAB on the local machine (R2023b) and the MATLAB Online (R2024b).

From the release notes, it can be observed that the 'speech2text' function requires a 'clientObj' parameter as the first argument up to MATLAB R2023b.

For more details, refer to the 'speech2text' release notes: https://www.mathworks.com/help/audio/release-notes.html?startrelease=R2023b&endrelease=R2024a&rntext=speech2text&groupby=release&sortby=descending&searchHighlight=speech2text#mw_c2706f73-9725-45c8-a190-8f3e74a6cdb7

To resolve the issue and ensure compatibility with MATLAB R2023b, you can modify the code snippet to include a ‘clientObj’ parameter as follows:

transcriber = speechClient("wav2vec2.0"); 
transcript = speech2text(transcriber, y,fs) 
transcript = transcript.Transcript;
