Offline low-cost voice command recognition controller solution

Offline low-cost voice command recognition controller solution

Program overview

This solution is an offline voice recognition solution that can fully and accurately recognize voice commands in an offline state, which is convenient for the design and use of smart products.

Function definition and performance index

Features:

1. Specific and simple offline voice recognition function, about 20 tune instructions, effective recognition distance 3m;

2. With 8-channel touch key input;

3. Support two PWM light control signals (frequency>20KHz, level 256);

4. With voice broadcast function, direct drive 8R 1W speaker;

5. Other extended functions can be customized;

Technical parameters: The effective recognition distance of voice commands is 3m, and the recognition rate is as high as 95%;

Communication interface: 1. It can support SOC scheme without other interfaces; 2. If you need to work with other MCUs, you can use the I2C interface;

Solution advantage

Low cost, high voice recognition rate, long recognition distance, and customized software programming is provided, which can replace the MCU of the original solution, so while voice recognition can be added to the old product, there is basically no need to increase the cost;
