微信具有隱藏的變聲功能和語言切換功能。當點擊輸入框時，按下麥克風按鈕，然後再點擊變聲，就能切換成蠟筆小新或東北老哥等聲音。然而，此功能的可用性會因微信版本而異。

此外，微信還提供針對英文、日本語和其他語言的聽寫設定。使用者可以選擇欲輸入的語言，然後對著麥克風留言，系統會顯示出該國語言的文字。這項功能的精準度相當高，另外只需持續按住顯示的文字，就能透過翻譯功能轉換成中文。

WeChat has a hidden voice-changing feature and language-switching functionality. When you click on the input box, press the microphone button, and then click on the voice-changing option, you can switch to voices like Crayon Shin-chan or Northeast Brother. However, the availability of this feature may vary depending on the WeChat version.

In addition, WeChat also provides transcription settings for English, Japanese, and other languages. Users can choose the desired input language, then speak into the microphone, and the system will display the text in that language. The accuracy of this feature is quite high. Furthermore, by continuously holding down the displayed text, you can use the translation feature to convert it into Chinese.
