2. Configuring for DuerOS
2.4. Interactive Function
2.4.1. Voice Recognition
When ESP32-LyraTD-MSC is connected to DuerOS, ESP32 supports “Alexa” as a
wake-up phrase. Saying “Alexa” to the board prompts the following response in
Chinese: “nin hao you shen me fen fu” (meaning: “Hi! How can I help?”). Users can talk
to the board and instruct it to play songs and news, or they can perform other similar
voice interactions. Here is an operation sample:
•
Say “Alexa” to the board, and it will respond in Chinese by saying: “nin hao you shen
me fen fu” (meaning: “Hi! How can I help?”).
•
Then, ask the following question in Chinese: “tian qi zen me yang” (meaning “How is
the weather?”).
•
The board will respond in Chinese by saying: “jin tian yin zhuan duo yun” (meaning
“It’s getting from overcast to just cloudy today.”).
2.4.2. Buttons
•
The “Play” button can be used to play or pause the audio streaming.
•
The “Vol+” and “Vol-” buttons can be used to adjust the volume of the sound. Press
them repeatedly until you reach the desired sound volume.
