What is a sine wave speech?

Sine-wave speech is an intelligible synthetic acoustic signal composed of three or four time-varying sinusoids. Together, these few sinusoids replicate the estimated frequency and amplitude pattern of the resonance peaks of a natural utterance (Remez et al., 1981).

What is sine wave examples?

Other examples of sine waves as they arise in the natural world include ocean waves and sound waves. When a sine wave is superimposed on a second sine wave of the same frequency, phase and magnitude, the original signal retains its shape, unlike non-sinusoidal waveforms.

Is speech signal sinusoidal?

Sinusoidal representation of acoustic signals has been an important tool in speech and music processing like signal analysis, synthesis and time scale or pitch modifications.

What is sine audio?

The waveform of a pure sinusoidal tone which has a waveform defined by a mathematical function derived from a classic periodic oscillation, such as the movement of the tip of swinging pendulum. In a musical context, a sine wave contains only a single fundamental frequency, and no harmonics.
