Place it at the exact moment a character switches voices in an edit, then follow it with Anime Wow as the reaction. Put Vine Boom just before it to mark the switch, so the change hits harder in a short clip.
About this sound
This 0.6-second clip says 'my voice has changed' in Russian through a voice-changer effect that makes the speaker sound altered and unfamiliar. It feels funny and slightly uncanny, like catching yourself mid-transformation, because the line states the change while the effect proves it. The recording comes from a voice-changer tool, which gives it that processed delivery.
