Nt1310 Voice Recognition

Satisfactory Essays

. The second component of this project is the chip that is going to receive the analog signal from the microphone sensor when the person speaks. It is the critical part of this project. The chip that will be proposed in this project called voice recognition 3. This chip has a small flash memory that can save 80 voice commands. However, the maximum number of the voice commands that can work at the same time are 7 voice commands. Any word can by a command (2). However, we must train the module first before let it recognizing any voice command. This chip has two controlling ways. The way that is going to be proposed in this project called serial UART because it is easier to train it and save the commands in the memory. Also, perform the required functions which are “go forward, stop, left, right and reverse”. …show more content…

The recognition accurate of the chip is 99%. Comparing this chip to the previous version of this chip, voice recognition chip 3 is better for our project. Voice recognition chip 2 supports 15 voice commands and the only 5 commands can work at the same time. You might say the project need just 5 voice commands. Yes. However, the time for voice recognition v2 to response is longer than the time for voice recognition v3 because the mechanism of first one is to separate the voice commands into three groups while training and recognition
