ASR Board for Arduin is discontinued now, we recommend other Arduino Microcontrollers
as a suitable replacement.The ASR Board is an opensource voice recognition control board based on Arduino. Users are able to set keywords simply via host software, without any trainning or recording in advance. It is a highly efficient universal voice recognition module for Arduino.
The ASR Board is able to recognize 35 candidating sentences at a time, from single words, phrases to short sentences that are no more than 38-byte string. Multiple scenarios are supported with mono system. (Note: The number of keywords is inversely proportional to the length of keywords). After secondary development, users can have a maximum number of 50 single words, phrases or short sentences that are no more than 79-byte-string). Asr 委员会能够一次识别35个候选句子，从单个单词、短语到不超过38字节字符串的短句。 单一系统支持多种场景。 (注意: 关键字的数量与关键字的长度成反比)。 在二次开发之后，用户最多可以拥有50个单词、短语或不超过79字节字符串的短句)
Besides recognizing voice, the ASR Board can also play audio files in AD4 format, enabling voice interactions. Communication with other Arduinos/microncontrollers can also be achieved via serial port. The module pre-set idle digital/analog ports for secondary development, allowing you to do further customizations. It is also compatible with Xbee and APC220 wireless module, which means you are free to add wireless voice control functions to projects. 除了识别语音，ASR 板还可以播放 AD4格式的音频文件，支持语音交互。 与其他 arduino / microcontrollers 的通信也可以通过串口实现。 模块为二次开发预先设置空闲的数字 / 模拟端口，允许您进行进一步的定制。 它还兼容 Xbee 和 APC220无线模块，这意味着您可以自由添加无线语音控制功能的项目 Note: This module ONLY works with external power supply. 注意: 本模块仅适用于外部电源
