Tinker Board : Smart-Mirror 설치

Raspberry PI에서 사용햇던 Smart-Mirror를 Tinker Board에 적용해보았습니다. Raspberry PI이 보다 실행 속도가 많이 빨라 졌습니다. 모니터는 Raspberry PI 7인치 모니터를 사용했고, 미러용 필름은 붙이지는 않았습니다. 마이크의 입력은 4극 스테레오 Y케이블을 사용해서 특별하게 마이크 설정없이 바로 사용이 가능했습니다.

음성 인식용으로 사용했던 마이크

4극 스테레오 (3.5) Y케이블

Tinker Board용 Audio 단자는 마이크 입력과 오디오 출력이 동시에 가능한 4핀 단자로 아래와 같은 4극 Y케이블을 이용하면 마이크 입력과 오디오 출력을 분리해서 사용 할 수 있습니다.

4극 스테레오 (3.5) Y케이블에 마이크 연결

Node.js 6.x 설치

$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
$ sudo apt-get install -y nodejs

Smart-Mirror 소스 다운로드

$ cd ~
$ git clone https://github.com/evancohen/smart-mirror.git

Smart-Mirror 관련 라이브러리 설치

$ sudo apt-get install sox libatlas-base-dev

Smart-Mirror 설치

$ cd ~/smart-mirror
$ npm install

Smart-Mirror 실행

$ npm start

개발자 콘솔로 Smart-Mirror 실행

$ npm start dev

관리 페이지 접속

관리 페이지 오른쪽 상단 톱니바퀴 아이콘을 선택하면 Smart-Mirror 설정 화면으로 이동이 가능합니다.

언어 설정 변경 (한국어 명령이 가능하도록 설정)

Language 항목의 설정을 ko-KR로 수정

자신만의 호출 키워드 생성

이 작업은 마이크를 사용하여 smart-mirror가 대기 모드에서 명령 모드로 변경 됩니다.

키워드 생성은 사이트(https://snowboy.kitt.ai/hotword/47)에서 하시면 되고 저는 팅커보드의 약자로 팅커벨로 했습니다.

Snowboy에서 생성한 Tinkerbell.pmdl 파일을 smart-mirror가 설치된 경로(/home/linaro/smart-mirror)에 복사합니다.

호출 키워드 등록
