Okay. I think I can work within that process, but I have a few questions to make sure I understand the details.

1. Will pocketsphinx only recognize full names if my corpus contains only full names?

2. Does the fallback method utilize the lookup list in AcousticModelEnglish? i.e. Would an error in the English lookup list cause problems with the fallback method?

3. If I duplicate (in the Finder) the AcousticModelEnglish.bundle, rename it to AcousticModelCustom.bundle, add it to my project and point the pathToModel method to the Custom bundle, would you expect that to work? Or, should I just modify the lookup list in the English bundle?

I just noticed that “key_west” in the English LanguageModelGeneratorLookupList.txt has an ‘_’ (underscore) instead of a ‘-‘ (dash).

Not sure if that is intentional or not.

Awesome, Thanks.

Editing these entries for the last day or so, I think I can now write in full grapheme!

Okay, great.

…but you can’t have any spaces in the word entry before the tab.

If no spaces are allowed before the tab, then I need to add the phrases as “John-Henry-Doe”. Are the dashes ignored when generating? Do they change inflections or timing anything like that?

You could also add JOHN and HENRY and DOE separately and a request for the phrase “John-Henry Doe” should then find all of your added words.

I do not want to add the names separately as only specific full names are used. For instance “John Doe” and “John Henry Doe” are used but “John Henry” is not. My thinking is that the recognition will be more accurate with phrases than it will be with simpler words that are used to make the phrase. True?

Yes, but this regards the generation of the language model or grammar, not the LanguageModelGeneratorLookupList entries, which should just be added in whatever case the rest of the list is in (uppercase, lowercase, or mixed case). The framework will make sure to normalize requests and the entries to the same case during lookups so you don’t have to worry about case.

Okay, to clarify the case answer… If my Array contains “John-Henry-Doe”, and the entry in the LookupList is “john-henry-doe” will that match? And what is returned in the string of recognized text?

Hi Halle,

1. Can I create a phrase in the LookupList? i.e..

JOHN HENRY DOE<tab>JH AA N HH EH N R IY D OW

2. Can the phrases contain punctuation like ‘ (apostrophe) and – (dash)? i.e.

JOHN-HENRY DOE<tab>JH AA N HH EH N R IY D OW

3. I recall reading on the forum somewhere the the words do not need to be in all caps any more. Is that correct? i.e..

John Henry Doe<tab>JH AA N HH EH N R IY D OW

As I was copying the code I found the problem.

Apparently,

generateLanguageModelFromArray(words, withFilesNamed: name, forAcousticModelAtPath: "AcousticModelEnglish")

is not the same as

generateLanguageModelFromArray(words, withFilesNamed: name, forAcousticModelAtPath: OEAcousticModel.pathToModel("AcousticModelEnglish"))

(damn noobie)

Thanks for your help.

Well, I have looked it over a bunch of times and re-built the app from the tutorial and I always get the same error.

I checked the AcousticModelEnglish.bundle and it appears to be properly added to the project (well, as fas as I can tell, anyway). I went through the steps in the tutorial again with a brand new project and followed the steps exactly. I checked the built application that is downloaded to the phone and the AcousticModelEnglish.bundel is at the root level of the app bundle. It is also selected as a member of the target in Xcode. The Framework Search paths are updated automatically when it was added to the project.

Any suggestions?

I have included the log from the recent re-built project which is simplified. It looks mostly the same as the previous one, but maybe there is something in it that will help determine what I am doing wrong.

I spaced the message out to be more readable and changed the name of the app. No other edits. After I posted, I noticed that there are other logging routines that I had not enabled. Should I do that and re-submit the log?
