If you are referring to portable generators, the answer depends upon whether it uses a brushless alternator. Some generators have automatic voltage regulation which will compensate to a degree for engine speed and supply a relatively constant output voltage. Brushless alternators have no feedback mechanism and depend upon constant engine speed for their output voltage. If you increase the engine speed the output voltage will increase.

Conservation of Energy.
Power In = Power Out.
The more power used to spin the Generator, the more power the generator produces.
The power a generator produces is in the form of Voltage or current.
There are regulators built into Generators that limit the voltage and/or current from either being too high or too low. If there is no regulation, then the current and/or voltage is allowed to be unregulated and change as a function of the Spinning.

In a generator there are coils wound around iron cores.
If the generator spins faster the magnetic field in the iron changes more quickly and therefore induces a higher electric voltage in the coils.

Generators have governors as part of their design. This prevents overvoltages from occurring. But remove them and you will get in increased voltage with increased speed.
