ELECHOUSE语音识别模块是一个紧凑且易于控制的语音识别板。

该产品是与扬声器相关的语音识别模块。它总共支持多达80条语音命令。最多7个语音命令可以同时工作。任何声音都可以作为命令来训练。用户需要先训练模块，然后才能识别任何语音命令。

该板有2种控制方式：串行端口（全部功能），通用输入引脚（部分功能）。板上的通用输出引脚可以在识别相应的语音命令时产生多种波形。

什么是新的？
我们已经有语音识别模块V2。它总共支持15条命令，而同时仅支持5条命令。

在V2上，训练语音命令时将其分为3组。而且只能将一组（5个命令）导入到Recognizer中。这意味着同时只有5个语音命令有效。

在V3上，语音命令像库一样存储在一个较大的组中。库中的任何7个语音命令都可以导入到识别器中。这意味着7条命令同时有效。

Overview

ELECHOUSE Voice Recognition Module is a compact and easy-control speaking recognition board.

This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.

This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.

What’s new?

We already have Voice Recognition module V2. It supports 15 commands in all and only 5 commands at the same time.

On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the same time.

On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.
