Hi,

I'm asking if it's wrong to use Trainer HT in production while the client is forcing us to use one key word in utterances, that's their business needs.

We have 20 utterances for each Intent and it's wokring fine right now using Trainer HT , When exactly to use Trainer TM ?

Note : We switched to trainer TM with the same utterances and it's not working fine with resolving the Intent.

For example : I want to ask about checking my balance (Utterance) 

Trainer HT result : 100%
Trainer TM result : 45 %

I tested the same exact utterance for both why it's not 100% in both cases ?
