These devices are a popular gift for elderly relatives or retirees doing a bit of traveling, and the last thing they need is to spend all day messing around with a faulty Bluetooth connection, which is why the top picks on this list all have big screens. You won't need to pair them with your phone, and they support a wide variety of languages. More niche options have features like offline translation, but the language selection is limited. https://www.upwork.com/o/jobs/browse/?q=translator+video
The palm-sized ECTACO Partner 900 is ideal for those interested in learning Spanish. It instantly converts voice text by repeating it aloud or speaking it in Spanish or English, and also has a roster of other features to help you learn the language. Take a photo of text (such as a restaurant menu) and it instantly converts it to English (an Internet connection is required for this part of the program). There’s also a talking picture dictionary and phrasebook, as well as a full language-learning program with linguistic crosswords and pronunciation assistance. The translator measures 6 x 3.5 x 0.7 inches and weighs 9.8 ounces.
