I made a Pinyin to Gwoyeu Romatzyh translator (so i can learn how to pronounce and practice speaking Mandarin).
It can be hard to learn how to say things correctly in Chinese, especially if you are new to tonal languages. So, i madeĀ a tool that can help you change Pinyin to Gwoyeu Romatzyh, which is a more accurate representation of Mandarin Chinese sounds, can be very useful.
