Explanation:

With increase in temperature, Velocity of sound in gas increases (v∝√T).
Change in pressure has no effect an velocity of sound in gas if temperature remains constant.
And the speed of sound in air doesn’t effected by phase, loudness, pitch, amplitude, or frequency.
The velocity of sound in air increases as the humidity increases.
