In a video review of the updated app, Mashable found that conversation mode can be a bit hit and miss, occasionally getting things very wrong indeed. The update goes one step further and can now listen for two languages simultaneously, meaning two people can speak into a device and have their words translated into the other person's language. The old version of the Google Translate app allowed two people to speak to one another across languages by just touching a button to change the language detection mode. So how well does it work? Conversation mode The app has a range of new functions including a conversation mode, where two people can speak to one another in their own tongue with Google translating live, and a scanning mode, which translates text instantly on screen. Google has updated its flagship translation app with new tools that promise to help even the most monolingual of travellers successfully negotiate their way around foreign parts.
