[Harz]

Thanks a lot for your help. We appreciate your advice and suggestions. Soon we’ll regenerate our model to 8kHz and test performance again. In any way it will be nice to realize possibility to stop delayed recognition, because it’s don’t take any sense, but spend too much time. Here is log from iPhone 4. As you can see, delay between sending stopListenning and actually it’s stopping is about 3 minutes.

[Harz]

Thank you for advice. I will implement it soon.

Currently our vocabulary contains 2800 words including (2) and (3) variants for some words. But we tested application on about 8000 words vocabulary and 20M language model (lm.dmp) It worked fast enough with RapidEars on iPhones 5/5s.

[Harz]

Thanks a lot Halle. I’m using 16kHz semicontinous model generated from wavs and text corpus. There are no other modifications in OpenEars except pathToModel method.
Does it make sense to downsample model to 8kHz without losing an acuracy?
