The process that does NOT slow down the speed of reading among the given choices is Immersion.

Here's why:

1. Regression: This is when your eyes go back to re-read a word or sentence, which slows down your reading speed.

2. Immersion: This is when you are fully engaged in the text you are reading. It does not slow down your reading speed, but rather, it can enhance comprehension and enjoyment of the reading material.

3. Subvocalization: This is when you 'say' the words in your head as you read, which can significantly slow down your reading speed.

4. Eyespan Expansion: This is when you train your eyes to read more than one word at a time, which can initially slow down your reading speed until you become proficient at it.
