离线低成本语音指令识别控制器解决方案

方案概述

本方案是离线语音识别方案，在离线的状态下可完整精准识别语音指令，方便智能产品的设计使用。 

功能定义及性能指标

功能：

1、具体简单的离线语音识别功能,大概20调指令，有效识别距离3m；

2、具有8路触控按键输入；

3、支持两路PWM灯控信号（频率>20KHz，级数256）；

4、具有语音播报功能，直驱8R 1W喇叭；

5、可以客制添加其他扩展功能；

技术参数: 语音指令有效识别距离3m，识别率高达95%以上；

通讯接口：1、可以支持SOC方案，无需其他接口；2、如果需要配合其他MCU工作，则可以使用I2C接口；

方案优势

低成本、语音识别率高、识别距离远、另提供客制软件编程，可以替换原来方案之MCU，所以可以给旧产品添加语音识别的同时，基本不需要增加成本；

Offline Low Cost Voice Instruction Recognition Controller Solution

Outline of the plan

This scheme is an off-line speech recognition scheme, which can recognize speech instructions completely and accurately in the off-line state, and is convenient for the design and use of intelligent products.

Functional Definition and Performance Indicators

Functions:

1. Specific and simple off-line speech recognition function, about 20 commands, effective recognition distance of 3m;

2. It has 8 touch keys input.

3. Supporting two PWM signals (frequency > 20KHz, series 256);

4. With voice broadcasting function, direct drive 8R 1W horn;

5. Adding other extended functions can be customized.

Technical parameters: The effective recognition distance of voice instructions is 3m, and the recognition rate is over 95%.

Communication interface: 1. It can support SOC scheme without other interfaces; 2. If it needs to cooperate with other MCUs, it can use I2C interface.

Program advantage

Low cost, high speech recognition rate, long recognition distance and custom software programming can replace the original MCU, so it can add voice recognition to old products without increasing cost.
