What you see right now is a Robot. He is asking you what voice should he have. The voices are either alto, tenor, squeak, or giant. Now we have the Languages. Pick one of the 24 supported languages in the Scratch TTS extension. The following languages are: Arabic, Chinese, Danish, Dutch, English, French, German, Hindi, Icelandic, Italian, Japanese, Korean, Norwegian, Polish, Portuguese (Brazilian), Portuguese, Romanian, Russian, Spanish, Spanish (Latin American), Swedish, Turkish, and Welsh. Then he will ask you what should he speak. He speaks whatever you type. In the Text to speech extension, a bad word detector is present. When a user attempts to input a bad word, no words will be spoken. Minor swears like "damn" or "hell" will not be spoken as well. Additionally, all bad English words will not said whatever the language is, although bad words in other languages will only not be said when that language is chosen.
