[D] Why do top speech/audio conferences like ICASSP and Interspeech have very high acceptance rates like 46%-48% ?

I have heard from my fellow Ph.D students and post-docs that the lower the acceptance rate of conferences, the higher their reputation. I see that this is true for Neurips, ICLR, ICML, ACL etc. But ICASSP and Interspeech are considered top conferences in speech/audio applications. So why are their acceptance rates so high?
