Can you make voice recognition on scratch?

Hello! I am o0yiii!

No, you only have one block that can access the microphone:

(loudness) // outputs the current loudness received in the range 0-100. returns -1 if no microphone is detected.

You do not have any ability to get the pitch of the sound and the loudness block also can not update fast enough for sound to be able to be accurately measured.

Yes and no. Scratch doesn't have any built in voice recognition but people have try to make it themselves (although it doesn't work that good).

voice recognition can be detected in the nuances of how loud you talk. these nuances can also be used to identify phrases or words. the closest one has gotten to this is VBVR 2 (https://scratch.mit.edu/projects/220747929/)

That’s true, but doing it that way would be quite hard and you cannot sample loudness fast enough for this to be reliable. Also, if there’s background noise louder than the voice, you can’t detect the voice at all.
