ToneBoard Input is a Chrome add-on developed by toneboard.keyboard. It is a Chinese input method designed specifically for language learners who want to practice typing simplified Chinese with correct tones using Pinyin.

For Mandarin Chinese learners, remembering the correct tones can be challenging, especially when using language learning apps or typing with standard Pinyin input methods. These input methods do not require users to input tones, making it easy to type the correct characters without actually knowing the correct tones. Additionally, these input methods often remember frequently used words or suggest complete phrases, which is not beneficial for language learners who need to practice their tone recall.

ToneBoard Input addresses these issues by requiring users to input tones along with Pinyin spellings before displaying word and character choices. This allows learners to practice recalling the correct tone for each syllable while typing. The functionality of ToneBoard Input is similar to the standard simplified Chinese Pinyin input method, with the additional requirement of inputting tones.

Overall, ToneBoard Input is a useful tool for language learners who want to improve their Mandarin Chinese typing skills and practice recalling the correct tones for each syllable. It provides a focused and immersive learning experience for those who are serious about mastering the language.
