How do I prevent the texts from changing when I change the language?

I am using an in-site language changing script with google translate. And I have a language-changing menu. I wrote the language names in this menu in their own language (For example, I wrote "Turkish" for "Türkçe".) and I want these texts to change in no way.

I'm using these scripts for translation:

    
<script type="text/javascript">
  jQuery('.switcher .selected').click(function() {if(!(jQuery('.switcher .option').is(':visible'))) {jQuery('.switcher .option').stop(true,true).delay(100).slideDown(500);jQuery('.switcher .selected a').toggleClass('open')}});
  jQuery('.switcher .option').bind('mousewheel', function(e) {var options = jQuery('.switcher .option');if(options.is(':visible'))options.scrollTop(options.scrollTop() - e.originalEvent.wheelDelta);return false;});
  jQuery('body').not('.switcher').mousedown(function(e) {if(jQuery('.switcher .option').is(':visible') && e.target != jQuery('.switcher .option').get(0)) {jQuery('.switcher .option').stop(true,true).delay(100).slideUp(500);jQuery('.switcher .selected a').toggleClass('open')}});
</script>
<li style="display:none" id="google_translate_element2"></li>
<script type="text/javascript">
    function googleTranslateElementInit2() {new google.translate.TranslateElement({pageLanguage: 'tr',autoDisplay: false}, 'google_translate_element2');}
</script>
<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit2"></script>
<script type="text/javascript">
  function GTranslateGetCurrentLang() {var keyValue = document.cookie.match('(^|;) ?googtrans=([^;]*)(;|$)');return keyValue ? keyValue[2].split('/')[2] : null;}
  function GTranslateFireEvent(element,event){try{if(document.createEventObject){var evt=document.createEventObject();element.fireEvent('on'+event,evt)}else{var evt=document.createEvent('HTMLEvents');evt.initEvent(event,true,true);element.dispatchEvent(evt)}}catch(e){}}
  function doGTranslate(lang_pair){if(lang_pair.value)lang_pair=lang_pair.value;if(lang_pair=='')return;var lang=lang_pair.split('|')[1];if(GTranslateGetCurrentLang() == null && lang == lang_pair.split('|')[0])return;var teCombo;var sel=document.getElementsByTagName('select');for(var i=0;i<sel.length;i++)if(sel[i].className=='goog-te-combo')teCombo=sel[i];if(document.getElementById('google_translate_element2')==null||document.getElementById('google_translate_element2').innerHTML.length==0||teCombo.length==0||teCombo.innerHTML.length==0){setTimeout(function(){doGTranslate(lang_pair)},500)}else{teCombo.value=lang;GTranslateFireEvent(teCombo,'change');GTranslateFireEvent(teCombo,'change')}}
  if(GTranslateGetCurrentLang() != null)jQuery(document).ready(function() {jQuery('div.switcher div.selected a').html(jQuery('div.switcher div.option').find('img[alt="'+GTranslateGetCurrentLang()+'"]').parent().html());});
</script>
