Why is she not at the soul party but can hear the people at the party?

I think you mean a virtual social platform, not a real physical party.

On the virtual social platform, users can communicate with other users in a way similar to voice chat. When users chat with others in a party, other users can hear other people's voices in the party through the voice function of the platform.

If you mean the actual physical party, then when a woman is not present, she can't hear other people's voices directly at the party. But if the client is recorded and disseminated by some means (such as live broadcast or recording), then she may hear the voice in the client's body through these means. Besides, if she has friends at the party, she can get the information of the party by communicating with them.
