Update verbal text formatter to use language

## Issue
Currently, the verbal text formatter is based on location of the route path. There are times when using the narrative language could help too.

### Examples:

1. Number formatting applied for countries outside the US that user maybe using US style English
2. Proper number formatting in the US for non-US-English languages
