Introduction
The intelligent voice control module is a deep learning voice recognition module for embedded products that includes a built-in neural network hardware acceleration module NPU, a standard ARM processor, and a variety of control and communication interfaces.
This module supports offline voice command word recognition in the near and far field with noise interference and can run a variety of neural networks.
Even if the device is not connected to the Internet, the user can effectively control the target electrical device and carry out the predetermined operation behavior by speaking simple command words.
The voice recognition module is a stand-alone module for intelligent voice processing. The main chip, a FLASH memory chip, a crystal oscillator, and a power chip are all part of the module (LDO). A 24-pin stamp hole serves as the external interface.
Features
1. Intelligent voice processing module
This module handles basic intelligent voice processing. It has comprehensive functions and interfaces. It is ideal for collaborating with electronic equipment motherboards as mounted modules to provide voice recognition and control functions.
2. Customized Voice control module characteristics
This intelligent voice-processing module has the following primary characteristics:
(1) A straightforward interface: a 24-pin stamp-hole interface.
(2) Simple power supply: only a single 3.3V power input is required.
(3) Extensive peripheral interfaces:
Interface for a single analog microphone input
UART interface with two channels
There is one I2C interface (multiplexed as UART at the same time)
There are five PWM output interfaces (multiplexed as GPIO interfaces at the same time)
(4) Firmware upgrade: UART0 interface online upgrade
(5) Small dimensions: 22 X 19 X 2.6 mm
(6) Low power consumption: 110mW is the typical working state power consumption.
(7) Module is light in weight (excluding the microphone and speaker)
