Microsoft Speech Platform - sampling rate and bit depth -


recognition results best if sampling rate , bit depth of audio match training data of system.

so, know exact sampling rate and/or bit depth (and/or stereo/mono) used in microsoft speech platform (newest, if that's important)? , if so, remember got information?

please note using ms speech platform, not sapi. unless both using same training data, that's not same afaik. precise - use this: http://msdn.microsoft.com/en-us/library/microsoft.speech.recognition.speechrecognitionengine.setinputtowavefile%28v=office.14%29.aspx

my first try based upon c++ code example given on page.

the microsoft.speech sr engine doesn't need training (unlike system.speech sr engine), , relatively insensitive sampling rate (will work > 8 khz sampling rate). 16 bit audio preferred, believe work 8 bit audio.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
