In order to find an English to Sinhala audio translator, you can use Google search engine. Personally, I recommend you use the online utility provided by Kapruka. All you need to do is to type the word you want to translate in the provided box and to click Search. After that, press Pronounce This in Sinhala and you will be able to hear the word in Sinhala language. Beside Sinhala, you can translate the words in Tamil.
