What is the difference between speech and music?

Compared with music, speech tends to be a well-controlled spectrum with well established and predictable perceptual characteristics. In contrast, musical spectra are highly variable and the perceptual requirements can vary based on the musician and the instrument being played.

How is speech signal different from other signals?

Speech signals are nonstationary in nature, means their statistical parameters like intensity and variance vary over time [11]. Speech signals may be stationary for a shorter period but when considered over a longer duration they are aperiodic.

What is the difference between voice and music?

Vocal music is music that uses and emphasizes the human voice. Sometimes instruments are used, but the voice is the most important part. Vocal music is the opposite of instrumental music, which uses any combination of instruments, such as strings, woodwinds, brass, or percussion, usually without the human voice.

What is the music signal?

A music signal is characterized by a rms voltage of 2 V and a bandwidth B of 15 kHz. A noise process adds a rms noise voltage of 4 mV to the music. Find the information rate and the signal-to-noise ratio of the music.
