Hi @AMULYA PONNURU 17BIS0031,

In order to identify words from an audio file, consider using the following MathWorks File Exchange submission: https://www.mathworks.com/matlabcentral/fileexchange/65266-speech2text

Here is an example:

% Reading and playing the recorded audio
[audio, fs] = audioread('recorded_audio.wav');
soundsc(audio, fs);

% Converting speech from audio to text using 'speechClient' which connects
% to use use third party API's for the conversion.
speechObject = speechClient('Google','languageCode','en-US');
outInfo = speech2text(speechObject, samples, fs);
>> outInfo.Transcript

ans = 

    "hello my name is Rahul"

>> outInfo.Confidence

ans =

    0.8640

Refer to the following MATLAb Answer and MathWorks documentation to know more:
