The image is a table from a document titled "Vowel-Length in American Speech." It provides data on the duration of vowels spoken by Americans, comparing short and long vowel sounds. The table includes numerical values for the average length of each vowel sound in milliseconds.

### Table Breakdown:

#### Columns:
1. **General American**: This column lists common English vowels categorized as General American.
2. **Short [i u ʌ e]**: These are the shorter versions of the listed vowels.
3. **Long [i u e o æ ə a]**: These are the longer versions of the listed vowels.
4. **Rel. Dur.**: This column shows the relative duration ratio between short and long vowel sounds.

#### Rows:
The rows list specific vowels, both short and long forms:

- **R**: Short is 13.2 milliseconds; Long is 17.4 milliseconds; Relative Duration (Rel. Dur.) is 1:1.3.
- **L**: Short is 15.3 milliseconds; Long is 18.8 milliseconds; Relative Duration is 1:1.2.
- **D**: Short is 15.4 milliseconds; Long is 20.4 milliseconds; Relative Duration is 1:1.4.
- **M**: Short is 17.8 milliseconds; Long is 23.9 milliseconds; Relative Duration is 1:1.3.
- **H**: Short is 16.1 milliseconds; Long is 23.5 milliseconds; Relative Duration is 1:1.5.
- **[Heffner]**: This row represents a specific speaker named Heffner, with short vowel duration of 16.3 milliseconds and long vowel duration of 21.9 milliseconds.

The table provides a clear comparison between the average durations of short and long vowels for each listed sound in American speech, along with how these durations relate to one another (the relative duration ratio).
