A big name in free online translation websites is Bing, which uses Microsoft Translator. You can select your input language or have the site automatically detect it as you type. If you have your microphone enabled, you can speak the text you want to be translated, which seems quite convenient if you ask us.

After you receive the translation, you have options to hear it aloud in a male or female voice, share it, or search Bing with it. Moreover, you can also give the translation a thumbs-up or thumbs-down if you would like to provide a little feedback. The free translator offers over 60 languages.

The DeepL Translator is a really cool tool that comes with its own definitions and automatic sentence completion options. You can choose from 26 languages and when you receive the translation, just double-click on a word for more details.

When you select that word in the translation, you will see a dropdown box with more options. You can also take a look at the word definition that pops up at the bottom of the page at the same time. Plus, you will see examples of the word being used in both the input and output languages. This is a great feature to have if you are trying to learn the language you are translating into.

On Translatedict, you can choose from over 50 languages and use auto-detect for your own dialect. Just enter your word, phrase, or even a large amount of text, pick the translation language, and hit the Translate button. You'll see the written translation and can click the sound button to hear it out loud.

If you're using the translation in written communication, you'll see helpful word and character counts at the bottom. This is great for texts or social media posts where you have limited space.

Translatedict also provides areas solely for the voice translator and text-to-speech feature.
