Language / (The Polish voice sample below) Native Polish Speaker Opinion Needed [16]

I am trying to hire a professional voice artist for various automated language prompts (telecom).
I was wondering if anyone on these forums could listen to the voice sample below, and advise if the voice actress sounds professional (accent, voice, pronunciation, etc.)

Thank you in advance for your opinions.
