Version: 70.0.3532.8
Reproduction Steps: 
1. Open ChromVox
2. Ctrl+L to focus the address bar.
3. Set character echo to none.
4. Start typing in a search query like "Things to do in Koh Samui".

Notice that ChromeVox reads the entire line on every keypress. It also appends "search" to every announcement after the key press. This is extremely distracting.
