Sample Program

Wifi connection is required to use text to speech function.

 

 

Program Flow

1: Download the program to the Micro:bit.
2: Press A and KOI will say “Hello” in English.
3: Press B and KOI will say “Good Morning” and “I am happy” in English.

The text to speech function only supports short phrases(2-3 words) and there must be no spaces between the words.

4: Press A and B and KOI will say “123” in Putonghua.

MakeCode does not support Chinese chracters but BaiduAI does, so BaiduAI will treat numbers as Chinese.

 

Sample Code

FAQ

Q1: There is no reaction after pressing the buttons on the Micro:bit.

A1: This is because KOI has a longer boot time than Micro:bit. When the power is turned on, Micro:bit has already ran the code for KOI initialization before KOI is ready.
Solution: Reset your Micro:bit after KOI has been turned on. (The trick is to let KOI power on completely before initialization.)

Q2: Does KOI work with 3V input?

A2: No, KOI only works with 5V.
