If you are carrying a Smartphone, you already have a Translator with you. You all must be knowing about the Messenger Bot released earlier which not only does the translation for you but it can also talk. Using that feature with your Smartphone, you can utilise the Messenger Bot feature for translation. If you have a Smartphone with Messenger Mobile, the experience is much better, and you can even use the Text-to-Speech feature (bot*say) to play audio back.
Make use of it on your Beijing Olympics Visit.
Check out the video demo.
