The image consists of two graphs that appear to be related to speech processing analysis.

### Top Graph:
- **Title**: "Original waveform and maximum peak in each period"
- **X-axis (Horizontal)**: Labeled as "Time (ms)" indicating milliseconds, with values ranging from approximately 2050 ms to 2150 ms.
- **Y-axis (Vertical)**: Labeled as "Amplitude," showing the amplitude of a signal over time. The amplitude is represented by blue lines that fluctuate up and down, indicating variations in sound intensity.

### Bottom Graph:
- **Title**: "Period length"
- **X-axis (Horizontal)**: Same as the top graph, labeled as "Time (ms)" with values ranging from approximately 155 ms to 205 ms.
- **Y-axis (Vertical)**: Labeled as "Period length (ms)," showing the duration of each period in milliseconds. The blue line represents a gradual increase over time.

### Key Observations:
- Both graphs are plotted against time, with the top graph focusing on amplitude and the bottom graph on period length.
- Red crosses are marked at various points along both graphs, likely indicating specific data points or significant moments within the analysis.
- The source of this image is cited as "https://speechprocessingbook.aalto.fi/," suggesting it's from a speech processing textbook or resource.
