include word boundaries in the biasing

[afaiza]

When I am using the word biasing based on CTC, is there a way to include word boundaries in the biasing?

For example, I see that when I boost the word "roam" I get many false accepts for the word "roaming".

Is it possible to boost only " roam "? (Note the spaces in the boundaries)
