Sims Voices audio files?

Soooo, long story short I’m planning on making a sim-story video, and to make it more fun I was thinking of doing a voice-over in simlish, exactly with my sim’s voice, so it’s not all just subtitles about what’s happening in the video and background music. It’s like my sim would be actually telling a story in simlish and the subtitles would be there just for translation.

Anyway, what I really want to know is if there’s any way to access sims voice audio files, so I could just put some random simlish words together to make it look like she’s telling some story in simlish. That way I wouldn’t need to make my sim do random stuff so she says something and then record her voice. Idk I’m just curious, I don’t mind recording but that would be just easier I guess :p
