The language policy and planning in the PRC are represented on various official central and local websites. The annual statistical analysis of Chinese words and characters used online are among the tasks, set by the authorities before the linguists. The technologies, allowing to recognize words within the character texts and to mark them as belonging to a particular part of speech in the isolating syllabic Chinese language are applied within the process of creating numerous text corpora, often accessible on the Web. Speech recognition and speech synthesis technologies based on AI are used in machine translation, on the official websites for Standard Mandarin learners, as well as in spoken corpora. Among the latter are dialect corpora created in Taiwan and Hong Kong and available online.
