Greetings,
Sure, I’d be happy to help out. Can you go into more detail about the specific accuracy-related issue you’re having and how you’d like it to improve? For instance, is too little speech being recognized overall, or are too many noises being recognized as if they were speech, or are known words being substituted for other known words, or is it something else? Most helpful would be examples of what is said (or what environmental sound is heard) and what the results are, compared with your ideal outcome for that situation.
In your email you also mentioned scheduledTimerWithTimeInterval (this is an Objective-C API rather than an OpenEars API), so I also wanted to make sure you aren’t arbitrarily timing out recognition periods, which will negatively affect accuracy, or using scoring to arbitrarily reject speech, which is another common way that accuracy can be harmed.
