Hello friends! In this tutorial, we will compare recorded spoken words using cross-correlation in MATLAB. We will load a test recording, compare it with five stored examples and inspect the similarity scores before choosing a result. This is a small template-matching experiment, not a general speech-recognition system. It can demonstrate how similar waveforms align in time, but changes in speaker, pronunciation, speaking speed and background noise can reduce its reliability substantially. The original audio package, result image and video remain included. We will update the deprecated audio-reading calls, normalize the comparison, use the file's actual sample rate and include an unknown result instead of forcing every recording into one of the five known words.
