reCAPTCHA multilingual capabilities

Thank you for your answer Igor, isn’t this solution will make it always same language? what if you have few languages? [we use wpml, and we have 3 languages]

Do you think this will work?

function custom_recaptcha_enqueue_scripts() {

		$current_lang = false;

		// lang from a multilang plugin (if any used)
		if(class_exists('WPGlobus')){
			// WPGlobus found
			$current_lang = WPGlobus::Config()->language;
		} else if(defined('ICL_LANGUAGE_CODE')){
			//Perhaps WPML??
			$current_lang = ICL_LANGUAGE_CODE;
		}

		// provided recaptcha langs from google (as of March 24th, 2016)
		$provided_langs = array('ar','af','am','hy','az','eu','bn','bg','ca','zh-HK','zh-CN','zh-TW','hr','cs','da','nl','en-GB','en','et','fil','fi','fr','fr-CA','gl','ka','de','de-AT','de-CH','el','gu','iw','hi','hu','is','id','it','ja','kn','ko','lo','lv','lt','ms','ml','mr','mn','no','fa','pl','pt','pt-BR','pt-PT','ro','ru','sr','si','sk','sl','es','es-419','sw','sv','ta','te','th','tr','uk','ur','vi','zu');

		if(in_array($current_lang, $provided_langs)) {
			// remove CF7 script call
			wp_deregister_script( 'google-recaptcha' );

			$url = 'https://www.google.com/recaptcha/api.js';
			$url = add_query_arg( array(
				'onload' => 'recaptchaCallback',
				'render' => 'explicit',
				'hl' => $current_lang ), $url );

			// load recaptcha with language parameter
			wp_register_script( 'google-recaptcha', $url, array(), '2.0', true );
		}
	}

How about similar code to this:

public function init() {
        $attr = $this->getAttr();
 
        //Site Key
        $this->pubkey = isset( $attr['public_key'] ) ? $attr['public_key'] : '';
        //Secret Key
        $this->privkey = isset( $attr['private_key'] ) ? $attr['private_key'] : '';
 
        // get_user_locale() was introduced in WordPress 4.7
        $locale = ( function_exists( 'get_user_locale' ) ? get_user_locale() : get_locale() );
        $user_locale_lang = substr( $locale, 0, 2 );
 
        $wpml_source_lang = isset( $_REQUEST['source_lang'] ) ? sanitize_text_field( $_REQUEST['source_lang'] ) : apply_filters( 'wpml_current_language', null );
        $wpml_lang = isset( $_REQUEST['lang'] ) ? sanitize_text_field( $_REQUEST['lang'] ) : $wpml_source_lang;
 
        $lang = isset( $wpml_lang ) ? $wpml_lang : $user_locale_lang;
 
        wp_enqueue_script( 'wpt-cred-recaptcha', '//www.google.com/recaptcha/api.js?onload=onLoadRecaptcha&render=explicit&hl=' . $lang );
    }
