Elechouse Voice Recognition Module V3.1 and Arduino - Setup and Tutorial

https://www.youtube.com/watch?v=YZ0SOAFXVAQ

Summary

TL;DR — This video tutorial demonstrates how to set up and use the Elechouse Voice Recognition Module V3.1 with an Arduino. It covers the hardware connections, software setup using the Arduino IDE and a dedicated library, and the process of training custom voice commands. The tutorial also shows how to use these trained commands to control the Arduino's built-in LED.

Key points

• The Elechouse Voice Recognition Module V3.1 requires soldering header pins and connects to the Arduino via its TX and RX pins (typically pins 2 and 3).

• A specific Arduino library needs to be downloaded from the Elechouse website, extracted, and installed.

• Voice commands are trained by uploading a sample program, entering 'train' followed by a command index, and speaking the command twice for confirmation.

• The module can store up to 80 commands but only 7 can be active simultaneously; commands must be loaded using the 'load' command before they can be recognized.

• The tutorial includes an example of controlling the Arduino's onboard LED using trained 'on' and 'off' commands.

• The voice recognition is speaker-dependent, not 100% accurate, and affected by background noise and microphone distance, but offers a simple, offline solution.

Takeaway — The Elechouse Voice Recognition Module V3.1 provides a straightforward, offline method for adding speaker-dependent voice control to Arduino projects, suitable for simple command recognition.

摘要 / Summary (zh-CN)

简而言之 — 本视频教程演示了如何使用 Elechouse V3.1 语音识别模块与 Arduino 进行设置和使用。内容涵盖硬件连接、使用 Arduino IDE 和专用库进行软件设置，以及训练自定义语音命令的过程。教程还展示了如何使用这些训练好的命令来控制 Arduino 的内置 LED。

要点

• Elechouse V3.1 语音识别模块需要焊接排针，并通过其 TX 和 RX 引脚（通常是引脚 2 和 3）连接到 Arduino。

• 需要从 Elechouse 网站下载一个特定的 Arduino 库，然后解压并安装。

• 语音命令的训练方法是上传一个示例程序，输入“train”后跟一个命令索引，然后清晰地说两次命令以进行确认。

• 该模块最多可存储 80 个命令，但一次只能激活 7 个；在使用前必须使用“load”命令加载命令。

• 教程包含一个示例，演示如何使用训练好的“on”和“off”命令来控制 Arduino 的板载 LED。

• 该语音识别是依赖于说话人的，准确率并非 100%，并且会受到背景噪音和麦克风距离的影响，但它提供了一种简单、离线的解决方案。

核心启示 — Elechouse V3.1 语音识别模块为 Arduino 项目提供了一种简单、离线的添加依赖于说话人的语音控制的方法，适用于简单的命令识别。
