Is it possible to change the reCAPTCHA language in different page?

1. User1121883‘s solution is for the old text reCaptcha v.1.0, not the modern behaviour reCaptcha. It has limited customization options now.
   So if you want to change other language for other custom language page you’ll need to play with reloading it with other language that would have different hl GET parameter:

   <script src="https://www.google.com/recaptcha/api.js?hl=en-GB"></script>
   

   Update

   I’ve done it client-side (demo), but you may do it server-side or also use this client side code.

   <button class="btn" onclick="btnclick();return false;">Load reCaptcha in Chinese</button>
   <script>
   function callback() { console.log("Chinese reCaptcha loaded"); }
   function btnclick()
   {       
           s = document.createElement("script");
           s.src="https://www.google.com/recaptcha/api.js?hl=zh-CN";
           if(s.addEventListener) {
             s.addEventListener("load",callback,false);
           } 
           else if(s.readyState) {
             s.onreadystatechange = callback;
           }
           // we remove the inner html of old reCaptcha placeholder 
           var oldRecaptcha=document.getElementById('g-recaptcha');         
           while (oldRecaptcha.firstChild) {
               oldRecaptcha.removeChild(oldRecaptcha.firstChild);
           }
           document.body.appendChild(s); 
   }  
   </script>
   

2. reCAPTCHA has a number of built in translations. You can use these by setting the lang parameter of the RecaptchaOptions:

   <script type="text/javascript">
   var RecaptchaOptions = {
      lang : 'fr',
   };
   </script>
   

   You can find more here:

3. I am using WordPress 5+, at wp-config.php

   $locale='sv_SE';
   

   (For example, in the case of the Swedish language)
