Language translation tools are software applications or online services designed to convert text or speech from one language to another. They use algorithms and databases of vocabulary and grammar rules to provide translations, making it easier for people to communicate across language barriers. Popular examples include Google Translate and Microsoft Translator. These tools can be used for various purposes, such as translating documents, websites, or conversations in real-time. While they are helpful for basic understanding, the accuracy of translations can vary, especially with idiomatic expressions or complex sentences. Users should be aware of these limitations when relying on them for important communications.
