Problem

When a task have multiple segments starting with a lowercase character, LanguageTool complains with UPPERCASE_SENTENCE_START error only for the first segment because the way of how segment batches are fed into LanguageTool makes LanguageTool to treat 2nd and further segment as NOT separate sentences.

Solution

Find a way to tell LanguageTool to treat each of 5 segments within a batch - as separate sentence.
