Since there is no rejecto for grammar, are there any strategies that could be done to simulate rejecto. One thing I just tried was I added every letter of the alphabet to the dictionary, and now almost anytime time it hears anything it picks one of those unless I say a phrase specifically in the dictionary which definitely is helping a lot.

Still confused why using a grammar it seems like it always wants to match with something in the dictionary. When I say almost anything it is always coming back now with one of the letters. It seems like there would be something that if in the time it started recognizing to the silence delay if there was what was clearly many syllables and words being said that it wouldn’t match to something with one syllable.

OK, I have done that. Still very weird behavior. I am testing this in pretty ideal conditions with no background noise and a very good headset and noise cancelling mic. When I say the words that appear in the dictionary it works flawlessly. When I saw am just saying other long phrases, it trips almost every time.

“THAT IS NOT VERY GOOD” and it came back with “NEGATIVE”
“THIS IS A TEST” and it came back with “MIRA SECURING”
“THIS IS A TEST” and it came back with “MIRA SPEEDS”
“THERE REALLY IS SOMETHING WRONG” and it came back with “MIRA RADIO-OUT”
“THAT IS WEIRD” and it came back with “READ ITEM”

I just copied the strings from the debug output. I am passing those to the generate grammar method in an NSDictiinary under a ThisWillBeSaidOnce and using JSGF to YES when listening.

Almost every phrase is at least two words. Most are two words or more. This is one dictionary…

I do understand I could use the the following format to build more of a hierarchy, but I am not sure if doing that will improve the results…

@{
ThisWillBeSaidOnce : @[
@{ OneOfTheseCanBeSaidOnce : @[@”HELLO COMPUTER”, @”GREETINGS ROBOT”]},
@{ OneOfTheseWillBeSaidOnce : @[@”DO THE FOLLOWING”, @”INSTRUCTION”]},
@{ OneOfTheseWillBeSaidOnce : @[@”GO”, @”MOVE”]},
@{ThisWillBeSaidWithOptionalRepetitions : @[
@{ OneOfTheseWillBeSaidOnce : @[@”10″, @”20″,@”30″]},
@{ OneOfTheseWillBeSaidOnce : @[@”LEFT”, @”RIGHT”, @”FORWARD”]}
]},
@{ OneOfTheseWillBeSaidOnce : @[@”EXECUTE”, @”DO IT”]},
@{ ThisCanBeSaidOnce : @[@”THANK YOU”]}
]
};

Yes. I put in slider in my app where at anytime I change it from 1 to 5 in 0.1 increments. When I get to 4.2 or above it doesn’t recognize most words. At 4 it usually recognizes words but it still trips up a lot when saying words where there definitely are no phrases anywhere near what is being said, .

Thanks Halle. So I am now using the grammar instead of language model and when I now say the phrases in the dictionary it is way more accurate than before which is great. One thing I am seeing though is because there is no Rejecto it seems to be overly aggressive in returning something in the dictionary even if what is being said is not even close to the phrases. Even when I say a single syllable, single word it will bring back phrases. Is there any strategies to mimic what something like Rejecto does or maybe I am missing something that can make things being said not trip it always wanting to bring back an utterance?

[jeffbonasso]

Thanks! I am using Rejecto which seems to only have the method…

Is there a similar one for generating a grammar while using Rejecto?
