Abnormal noise when activating voice assistant

Hello,

I have problem with my both assistants (bixby and google) on my Galaxy S21+ that 2 in 5 times my assistant starts sounding like a siren,sometimes even in mid sentence it's starts sounding like a air-raid siren.Sometims is even more it's like 5 of 5 times alwasys doing that or even not talking,but when i press back button the voice keeps up on the phone.

Does any other have the same problem. I'm on beta 9.14.

Thanks.
