There’s your problem. Asterisk has to wait for input to know whether the caller intends to type in more digits so that matches, or not. You can either remove that section or set the digit timeout[1] to a lower value - knowing that the caller will have to type in longer digits fairly quick.

If _XX. is only there to catch invalid numbers, you could use the i extension, instead.

It worked. I add ‘same => n,Set(TIMEOUT(digit)=2)’ code part into extensions.conf .

[English_lang_testing]
exten => s,1,NoOp(User Pressed 1 and go to English path)
   same => n,Set(TIMEOUT(digit)=2) 
   same => n,Background(software_en)
  
   same => n,Background(network_en)

   same => n,Background(sales_en)
 
   same => n,Background(hr_en)
  
   same => n,Background(finance_en)
   
   same => n,Background(again_en)

   same => n,Background(previous_en)   

   same => n,Background(exit_en)
   
   same => n,WaitExten(2)
   same => n,Set(tries=$[${tries} +2])
   same => n,GotoIf($[${tries}>=6]?Hangup,s,1)
   same => n,Playback(tryAgain_en)
   same => n,WaitExten(1)
   same => n,Goto(English_lang_testing,s,1)
