YarakuStick(β) is a portable voice translator that can be used with one hand.
Translation is done through our original online translation tool YarakuZen and then displayed,
along with the spoken source, as text on the display.
A key feature is that you just need to set the spoken source language and the desired translation output through
the touch screen at the start of the conversation. After that, throughout the conversation or meeting, voice recognition
will pick up the speakers' words and the Stick will translate and display it as text.
Your typical voice translation application or device will only begin translation after a person finishes speaking
or presses a button. In contrast, YarakuStick(β) will begin the translation process while a person is speaking
and keep going. Therefore, even if the speaker is interrupted or trails off, translation will keep up to that point
and display it as text letting other people understand the context.
