Speech Recognition Module for Children and Beginners to

Speech recognition module, non-specific speech recognition, easy operation, high precision, programmable
The speech recognition module is based on non-specific person speech recognition D3320SI-ASR:
(Speaker- Automatic Speech Recognition) chip developed a speech recognition module. The LD3320 chip integrates high-precision A/D and D/A interfaces, no Requires external auxiliary Flash and RAM, which can realize speech recognition/voice control/human-machine dialogue function, providing a real single-chip speech recognition solution.

Chip: LD3320
Communication protocol: I2C communication
Keywords: Up to 50 keyword entries
Connection : 4PIN anti-reverse connection line
Working voltage: 5V
Installation : screw and nut fixed
Module size: 4x2.1cm
This module has the following features:
1. Non-specific person speech recognition technology A list of recognized key words that users can dynamically edit without recording training. They only need to transmit the recognized key words into the chip in the form of strings, which will take effect immediately in recognition.
2. Support users to freely edit 50 key words at the same time, and identify at most 50 key words. End users can edit and update the content of key words at any time according to the needs of the scene. The number of words in each entry does not exceed 79 words.
3. There is a blue status light on the module. When it lights up, it means is being recognized, and when it turns off, it means the recognition is over.
4. The module adopts MCU+L D3320 design, and uses I2C communication with the application master, which greatly simplifies the difficulty of user wiring and programming. The module has four working modes, and the user can set the working mode through programming.
