Hi,
Yes, I’ve tested the accuracy against test recordings and it was fine, however I can’t test first-hand since I’m not a native speaker (which also means that it is possible there are underrepresented groups in the model that I’m unaware of, e.g. accents or genders, etc), and keep in mind that it is a non-tonal model. Most of the serious issues I’ve heard about with the model were due to the vadThreshold being too low, so you may want to start by increasing it higher even if you have a level where there has been improvement.
