English phonetic display solution

Hello, I need a solution to transform English text into ipa-symbol text, like we transform a single word “English” to “ɪŋɡlɪʃ”, a sentence “ I go to school” into “aɪ gəʊ tuː skuːl” . The goal is to automatically and “offline-ly” render every English text into ipa phonetic form. There were already two suggestions for this: -One is the chrome extension [login to view URL] . However I don’t want these disavantages: it lacks word stress mark and it uses American phonetic standard, meanwhile I would prefer standard British English denotation, and most of all I still have to select some texts by dragging the mouse to get ipa symbols showed. The reference American phonetic can be found here: [login to view URL] - The second one is this “Hanzi pinyin font”: it will show pronunciation for a Chinese word above every chinese character once we use this font [login to view URL] [login to view URL] So we may think of creating a “similar” font that uses british English ipa denotation database. However if there are some other solutions other than “fontizing” given text but still run smoother and lighter please suggest me. Let’s discuss this project together, thank you.
