From: An open dataset of multidimensional signals based on different speech patterns in pragmatic Mandarin
Visualization of speech features and quality assessment scores for S01. (a) Waveform: Displays the original waveform of the speech signal, reflecting the changes in audio data over time. (b) Short-time energy map: Displays the short-time energy changes of the speech signal in different periods. (c) Spectrum: Displays the intensity distribution of the speech signal at different frequencies and times. (d) Radar chart: Visualizes the relative performance of the three indicators of signal-to-noise ratio, energy contrast, and spectrum-to-noise ratio. The higher the score, the farther the point of the radar chart is from the center, indicating that the speech quality is better. The score range of the radar chart is 0 to 1, where 1 indicates ideal speech quality, and 0 indicates poor speech quality.
