From the audio, I feel that the Vox Ex Machina is a very powerful machine. The using of it will be used or already used in many ways in our daily life. The technology that mimics the human's voice was awesome and at that age sounds like ridiculous. Although the machine was made for war at the beginning, in the peaceful ages it will also be very useful.
This machine can be made such as the GPS or something else, also the most interesting part is that when the producer makes it, it can be controlled by the pitch. This will let the machine more useful, it can be used in the arts. We can think about that the outlook is like a piano, but sounds like a human is singing. Also, it can help the people to distinguished the male and female voices.
Also, the voder's keyboard looks like very easy to control, because it shaped as the hands. And the inside machine helps the people to decipher the digital instruction to the human's voice. In the WWll, it also played an important role. By the encryption of the voices of the leaders, the work of intelligence theft will become even harder, and even these encrypted voices will not be deciphered at all.
In the future, the voder machine can be smaller even invisible, at that time depends on the bionic technique, it will be very helpful for the society.
