Installation of smartphone app

• Install this app on your smartphone.
  This app is an app that converts voice to text and sends it by Bluetooth 3.0 SPP.

• After installing the app on your smartphone, add ESP_SPP_ACCEPTOR to your pairing device.

• After launching the app, select "ESP_SPP_ACCEPTOR" from the CONNECT menu to pair.

• From the LANGUAGE menu, select a country so that the app can recognize your native language.

• When you tap the microphone and speak, the spoken words will be displayed on the ESP32.

• After that, you add processing according to the spoken words.
  For example:
  Lamp on
  Lamp off
  

• I tried to say some Japanese. It's OK.
