First, we’re launching a new experimental pronunciation feature that lets you practice word pronunciations right in Search. For the visual learners out there, we’re adding images to our English dictionary and translation features to help you better understand the meaning of a word.
To do this, speech recognition technology processes spoken words by separating them into individual soundbites. Using machine learning, it then cross references your pronunciation with the pronunciation it expects.
Visuals are a helpful way to explain what a word means or even improve the retention rate.
Starting rolling out today, when you look up the translation of a word or its definition, you’ll start seeing images that give you additional context. This can be useful with words that have multiple meanings like “seal,” or words like “avocado” that aren’t commonly used in all languages or regions.
