On the left side of the photo is UU-002, on the right side is the speaker. The golden part immediately to the left of the green LED of UU-002 is a MEMS microphone. When speaking some phrases “Hey”, “How to do”, “Terrible!” and so on to the board, it answers with a female voice, “Yes” or “Eh?.” The emotional information judged from the sound input from the microphone is output from the terminal of this board, so if you connect with a microcomputer such as Raspberry Pi or Arduino, you can do even more advanced processing. It is also possible to make the sound file different.
I was planning to evaluate this UU-002 for experiments to extract emergency information from the quantification of urgency by voice analysis, but I enjoyed myself very much. Interesting technology.
