Yes - and No.
Yes; they are two measurements of sound waves.
No; changing one has no effect on the other in a sound wave.
Amplitude is the maximum positive displacement from the undisturbed position of the medium to the top of a crest.
Frequency refers to how many waves are made per time interval. This is usually described as how many waves are made per second, or as cycles per second.
The third measurement is wavelength: the distance between any two adjacent corresponding locations on the wave train. This distance is usually measured in one of three ways: crest to next crest, trough to next trough, or from the start of a wave cycle to the next starting point.
The speed of sound in air and other gases, liquids, and solids is predictable from their density and elastic properties of the media (bulk modulus). Thus the relationship bettween frequency and wavelength can be illustrated in the general exploration calculation using the wave relationship:
Wave velocity = frequency x wavelength
With the velocity of sound set to a constant (such as 343.4 meters per second in dry air @ 20 degrees C at sea level) this means that as frequency goes up wavelength goes down in an inverse linear relationship. Thus a 1 kHz tone would have a wavelength of 34.34 cm while a 2 kHz tone's wavelength would be 17.17 cm and so on.
Amplitude would have no effect on either frequency or wavelength; it would express only the intensity - the loudness - of a sound. It is the frequency/wavelength combination that dictates how low or high the tone is.

No you are right, all sound travels at the same speed regardless of amplitude or frequency IF it is in the same medium...and god I really hope Mark was joking when he wrote that answer...it is horribly incorrect.

Frequency is the rate at which a sounds moves.
Amplitude measures how much energy the(sound) frequency wave carries.

of course yes
amplitude in sound waves in form of transverse wave is its distance of crest or through in wave. more the amplitude there is loud note of sound , and smaller the amplitude softer is the note.
where as frequncey is no. of waves of sound produced in 1second.there fore more the frequency higher is the pitch of sound and thus vise versa. thus more is the shrillness of the voice

no. however speed, frequency and wavelength do have a relation. it is- speed=frequency*wavelength

yes.. when amplitude increases, freq also increases
