How do I change language characters?

Please see the images below to get a better idea of how to switch between keyboards in-app as well as within your own keyboards (iPhone6 used in this example).

1). First choose your language pairs (as well as corresponding genders for each language involved in your conversation)

2). Choose your language to type your phrase (this example uses English & Japanese) and hit the "Go" blue button on the bottom right to translate your phrase.

3). The phrase will show up in the written language you are translating to, as well as "speak" it for you to hear audibly above your typed section.

4). You can tap your original keyboard below to enter a new phrase.

5). The new translation will appear again in the above window, audibly translated again.

OR

6). If you have multiple language keyboards on your phone, you can always switch between languages available on your phone by hitting the "globe" icon before typing your selection (to be sure it is in the correct language for you to have translated properly).
