Can you join the slack linked at talonvoice.com or send an email to the address in my hn profile?
I'd probably start by asking for audio samples of you saying a couple of sentences and commands in english
Then I'd try them locally against a couple of speech recognition engines
Then talk about potential issues and ways to influence recognition accuracy
Then I can help you try out Talon for both dictation and command input
As an anecdote, I've heard from some of my non-english-native users that they need to avoid certain word sounds in commands (by changing the command trigger words) because their accent doesn't emphasize them enough for good accuracy.
