Forget about conventional robotic voices, AITalk will adopt a technical speech synthesis method of synthesizing a human voice, and it is capable of expanding its vocabulary as and when required. In fact, a single language might have up to 40 different kinds of personalities behind it, and this kind of variety would certainly make communicating with a robot a whole lot less impersonal.
It can also realize the emotional expressions of a human in order to suit the situation at hand. Of course, AITalk had to enrol the help of a mechanical humanoid to get the message across in its demonstrations, and the voice itself – its dulcet tone, the natural sound of it, makes it sound as though it hails from a human, although in reality it is synthesized speech. Unfortunately, it is not the android’s turn to look cold and lifeless, as you can tell by its rather gaudy looks.
