Introduction(br) This module is a fool-like non-specific person speech recognition module. No need to program, the user does not need to deeply understand the principle of speech recognition. The simple pinyin setting can be recognized, and the recognition result will be output through the serial port.(br) Production Process (br) Solder joints with SMT patches are more reliable. In order to reduce the circuit, it is more reliable to use SMT chip to process solder joints. In order to reduce the circuit(br) Module size: length 5.4cm width 3.7cm height about 2.5cm(br) design feature (br) 1, no programming basis, suitable for beginners.(br) 2, the computer input pinyin settings can be identified, easy to operate.(br) 3, TF card replacement voice file, larger capacity, more convenient.(br) 4, support loop detection, password detection, button detection, three major modes.(br) 5, serial output, convenient to connect with the microcontroller or other peripherals.(br) 6, non-specific person recognition, recognition of Mandarin, regardless of gender.(br) Instructions (br) The module and the computer are connected by a USB, and we can set the pinyin of the command by using our supporting software.(br) The following uses the setting "turn on the light" command as an example to demonstrate the usage.(br) Step 1: Write the “turn on the light” pinyin in the software, and customize a return value, “001” click “send”,(br) Step 2: Deposit the already created "0001.wav" audio file in the TF card, assuming "Light 1 for you right away"(br) Step 3: When the person says "turn on the light", the module will play the "0001.wav" in the card (it will turn on the light for you immediately!), and the serial port of the module will output hexadecimal 0x01, the microcontroller can receive.(br)
