Google Translate is undergoing its largest expansion yet, adding 110 new languages and reaching nearly a tenth of the global population, thanks to advancements in AI. Google's PaLM 2 language model has facilitated this growth by efficiently learning languages that are closely related, such as Awadhi and Marwadi, which are similar to Hindi, and French creoles like Seychellois Creole and Mauritian Creole. The expansion includes new languages like Afar, Cantonese, and Tamazight, bringing over 614 million people into the fold, with a significant focus on African languages.

Google's approach to language variety and dialects involves creating hybrid models that prioritize the most commonly used forms. For instance, the translation model for Romani combines elements from several dialects, including Southern Vlax Romani, to produce a more universally understandable output. The strategy follows their 2022 introduction of 24 new languages using Zero-Shot Machine Translation, which enables translation without prior examples, and their ambitious 1,000 Languages Initiative to support the world's most spoken languages.

Isaac Caswell, a Google software engineer, highlighted that ongoing partnerships with expert linguists and native speakers will further enhance the diversity and accuracy of Google Translate. The expansion underscores Google's broader commitment to integrating AI across its platforms, a trend mirrored by competitors like Apple and Microsoft, who are also embedding AI into their services. Google Translate can be accessed at translate.google.com or through its mobile apps for Android and iOS.
