KOI is able to recognize our commands after training.
Recognizing Voice Commands
Load the KOI Extension: https://github.com/KittenBot/pxt-koi
Blocks for circle tracing:
1: Download the program to the Micro:bit.
2: Press A and record the first command. A green color will be shown if the command has been successfully added. Otherwise red will be shown.
3: Press B to continue, you can now repeak step 2 and record the next command.
4: Repeat step 2-3 to record all your commands.
|AI Camera KOI has the capacity for 10 voice samples.|
5: Press A and B at the same time to recognize a command. A green color will be shown if KOI successfully recognizes your command, else it will show a red color. The command ID will be shown on Micro:bit.
Extension Version and Updates
There may be updates to extensions periodically, please refer to the following link to update/downgrade your extension.
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.
Q3: KOI displays red everytime I try to record my command.
A3: The noise level hasn’t been calibrated, it is essential to run the block before voice recognition.
