The results demonstrated that Japanese listeners were better at discriminating sine-wave speech than noise-vocoded sine-wave speech, with no significant difference in A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. Most studies so far have focused on visual awareness along with trial-by-trial reports of task relevant stimuli, which can confound neural measures of perceptual awareness with post-perceptual processing. On the one hand, the highly-intelligible sine-wave speech (SWS) has been 2) Generating Sine-Wave Speech: Sine-wave speech is generated by using a formant tracker to detect the formant frequencies found in an utterance, and then synthesising sine waves that track the centre of these formants.

It remains unclear how representations in this network differentially contribute to speech comprehension. These signals provide information about the time-varying structure of the three lowest vocal-tract formants, and this kind of acoustic structure is thought to be especially utilitarian for children in their efforts to discover language structure. Converts WAV files of human-speech to sinewave speech using linear predictive coding (LPC). SWS can be described as sounding like “whistles” or “sci-fi” in nature. That is why synthetic speech sounds voicelike, despite the mechanical quality of its articulation.
