c# - voice command to capture photo -

-

i use windows.media.capture.mediacapture in windows phone 8.1 app capture photo. instead of button, i'd trigger photo capturing process voice command (for example, if user says 'cheese'). how can detect such voice command?

you can use speechrecognizer class.

here's sample msdn:

private async void startrecognizing_click(object sender, routedeventargs e) {     // create instance of speechrecognizer.     var speechrecognizer = new windows.media.speechrecognition.speechrecognizer();      // compile dictation grammar default.     await speechrecognizer.compileconstraintsasync();      // start recognition.     windows.media.speechrecognition.speechrecognitionresult speechrecognitionresult = await speechrecognizer.recognizewithuiasync();      // recognition result.     var messagedialog = new windows.ui.popups.messagedialog(speechrecognitionresult.text, "text spoken");     await messagedialog.showasync(); }

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
