Robotic voice

The channel vocoder can be used to generate a classic robotic-voice
when modulated with speech, and it has found extensive use as a
special effect in Hollywood.

1. What is the characteristic of robotic voice?
2. Why movie director imagine and make robot speak with such voice?
3. How does a Real robot speak? Why?

No one here will do your homework for you.

Google for LPC.


Hardy

(A) Constant phase in the frequency domain.

I tend to think of this in the more modern approach of utilizing STFT's in
a phase vocoder.

Here is a brief overview of phase vocoder implementation:
http://eceserv0.ece.wisc.edu/~sethares/vocoders/phasevocoder.html

To implement a robotic voice effect, simply change the phase of each STFT
to a constant value.

(B) It's extremely cheap to implement.

Use none of the following:-

An artificial voice - usually sounding like it has a 'mouth' full of bread 
and marbles.

Because he's an unimaginative, follow-the-crowd, coke-sniffing brainless 
monkey.

They don't exist yet.

Especially your film studies homework.   EE homework maybe.  :)

That depends on your definition of robot...

despite the common word "vocoder", the phase vocoder and channel
vocoder are not the same thing.  they are different and do different
operations.

no.

I thought this created quite a good old fashioned monotone voice, with a 
pitch relative to the FFT step size?

why would changing the phase of each STFT (bin?) to a constant phase
cause of an input with varying pitch into a fixed pitch?
