Speech Recognition in MATLAB using Correlation

•  Download the complete project to get started.

• Presently in this bundle you will discover nine sound wav documents.

• Five of them are the recorded sounds which are as of now sustain in the MATLAB.

• Two are test records which will be perceived by the code.

• The staying two are achievement and disappointment records which will run on the off chance that you got the acknowledgment or if not.

• Give me a chance to explain the code a bit. As a matter of first importance, what we have to do is to transfer the initial five preparing sound documents in the product so and after that we have to test these fives records with the test records and we have to check which one is a greatest match.

• Presently in the event that you read the code from begin then you can see, above all else, I transferred the test document which I need to contrast and my specimens.

• After that I uploaded all the 5 tests furthermore get their relationship with the test.

• At long last toward the end I looked at the outcomes and on the premise of it I made sense of which one is right discourse record.
