The image is a graph that compares two audio signals over time, labeled "Original" at the top and "Synthesized" at the bottom. The x-axis represents time in milliseconds (ms), ranging from approximately 2050 ms to 2150 ms. The y-axis represents amplitude.

### Original Signal:
- The blue line represents the original audio signal.
- It shows a fluctuating pattern with peaks and troughs, indicating variations in sound intensity over time.
- There are noticeable changes in the signal's shape as it progresses from left to right on the graph.

### Synthesized Signal:
- The black line represents the synthesized audio signal.
- This line also fluctuates but appears smoother compared to the original. It has fewer peaks and troughs, suggesting a more consistent sound intensity over time.
- There are some areas where the synthesized signal closely follows the original (e.g., around 2075 ms), while in other parts it diverges significantly.

### Additional Details:
- The graph includes vertical dashed lines at specific points on both signals. These could represent timestamps or significant events within the audio data, but their exact meaning is not provided.
- At the bottom right corner of the image, there's a source link: "https://speechprocessingbook.aalto.fi/". This indicates that the graph might be from a book or resource about speech processing.

### People in the Image:
There are no people depicted in this image. It is purely an analysis of audio signals.
