No.
The untaged traffic from the PC goes to the native vlan , which is 10 .
switchport access vlan 10 will be used if trunk mode is down/disabled , the port will join vlan 10 .
So, in a trunk port , this command willnot do anything but no harm .
 
QUESTION :
if you use "switchport priority extend cos 1 " , this will change the PC data to cos 1 and voice remaim 5 , right ?
Does that mean voice and data are on the same vlan ?
Do you need to configure this port as trunk ?
Thanks !

What's the purpose of the "switchport access vlan 10"? Since it's in
trunk
mode that should be irrelevant (but harmless).
