Piano features an integrated 4 GB flash memory for storing your speech material. Dedicated buttons allow you to access word lists with ease. The screen also displays the word currently being pronounced.


Simply connect Piano to a USB port on your computer (no driver needed), and you can transfer exam results into Maestro or Noah database. With the live view feature, you can have a wide view of the examination in progress on the computer display.
