Выпуск №5. голосовое управление умным домом


голосовое управление умным домом

В этой статье я опишу процесс распознавания речи системой MajorDoMo на моей малинке. Кто не в курсе о MajorDoMo читайте здесь и о моей конфигурации здесь .

Итак, общая схема физических устройств:

 

1  этап

Произносит ключевое слово – «Анжелика»

V3 Module распознает и ардуино передает сигнал на wi fi модуль Wemos D1 Mini, который шлет http запрос серверу («http://192.168.0.101/objects/?script=commandRPI») MajorDoMo на запуск сценария включения микрофона на raspberry Pi и записи с последующим распознованием с помощью сервиса Google Speech API

 

 

 

2  этап

Произносит команду – «Включи музыку»

Raspberry Pi включает микрофон и делает 10 секундную запись команды и шлет этот файл на распознование гуглу и полученный ответ вставляет в GET запрос, который выполняет скрипт с поиском шаблона системы MajorDoMo по сказанной команде (подробнее о моих шаблонах здесь).  

 

Имеем три устройства (ардуино , Wemos D1 Mini, raspberry Pi) которые программируются следующим образом:

    1. В ардуино заливаем скетч. В мониторе порта ардуино набираем train 0 и записываем ключевое слово (не используемое в обычной речи). Набираем train 1 и т.д. - повторяем это слово с разных расстояний (до 5 раз). Записываем в память V3  модуля (load 0 1 2 3 4)

  1. В системе MajorDoMo создаем сценарий commandRPI со строчкой кода:
exec('sudo /home/pi/script/stt.sh');

Также, если мы хотим, чтобы по команде «Включи музыку« через протоколы распберри gpio включилось реле, управляемое звукоусилителем с колонками, в системе должен быть шаблон, который включает реле и запускает плейлист:

if (getGlobal('Colonki'.'.'.'status')=='0') {
  callMethod('Colonki.turnon');
}
say("включаю музыку");
runScript("SetMusicStatusOn");

file("http://:12345@192.168.0.101:8080/requests/status.xml?command=pl_empty");
file("http://:12345@192.168.0.101:8080/requests/status.xml?command=in_play&input=/share/tancy/");  

У меня в расшаренной папке /share лежит музыка разложенная по жанрам/папкам

  1. В raspberry Pi в папке /home/pi создаем папку script и добавляем туда файл stt.sh
#!/bin/bash
export AUDIODEV="hw:0"
echo "speaking ..."
arecord -B --buffer-time=1000000 -f S16_LE -r 16000 -d 5 -D plughw:1,0 /home/pi/script/send.wav

echo "waw-flac"
flac -f  /home/pi/script/send.wav -o /home/pi/script/send.flac

echo "Converting..."
curl -X POST --data-binary @/home/pi/script/send.flac --header 'Content-Type: audio/x-flac; rate=16000;' 'https://www.google.com/speech-api/v2/recognize?output=json&lang=ru-ru&key=ПолучитеСвойКлючНаГуглАпиИВставтеЕгоСюда' |  cut -d\" -f8 > stt 
value=`cat stt`
arr=("$value")
echo ${arr[@]} | cut -d ' ' --output-delimiter=' ' -f 1- > stt2
echo 'http://192.168.0.101/command.php?qry='> stt1
echo "`cat stt1``cat stt2`" > stt4
value2=`cat stt4`

curl ${value2// /%20}

 

Вот и все, подытожим:

Я говорю «Анжелика», v3 модуль+arduino распознает и дает команду WemosD1 Mini, который запускает скрипт распберри на включение микрофона и запись. Я озвучиваю команду «включи музыку» и распознанный гуглом ответ запускает шаблон, который выполняет код запуска скрипта включения колонок и проигрывания плейлиста. Шаблоны в MajorDoMo строятся быстро и программируются просто. Таким образом мы можем включать или выключать любые приборы в доме и за его пределами... Например у меня пока реализованы следующие шаблоны:

  • Музыка (Мантры, Релакс, Детская, Рок и др. по настроению)
  • Какая погода?
  • Что такое? Кто такой? (выдергивается и озвучивается информация с википедии)
  • Онлайн радио
  • Режим релакс (включается светодиодная лента с программируемым режимом - зеленно-желтой змейкой и музыка релакс)
