ios - Clear input of SFSpeechAudioBufferRecognitionRequest after every result (Swift3) -


i have integrated speech text through appcoda tutorial. problem facing want user can write/edit himself, sfspeechaudiobufferrecognitionrequest doesn't take consideration thing user has typed.

what's way send user typed input in sfspeechaudiobufferrecognitionrequest or way clear sfspeechaudiobufferrecognitionrequest input params before sending new request.

thanks in advance.

here use create recognition request: 

func recordspeech() throws {     // cancel previous task if it's running.     if let recognitiontask = recognitiontask {         recognitiontask.cancel()         self.recognitiontask = nil     }      isrecognizing = true     self.delegate?.recognitionstarted(sender: self)      let audiosession = avaudiosession.sharedinstance()     try audiosession.setcategory(avaudiosessioncategoryrecord)     try audiosession.setmode(avaudiosessionmodemeasurement)     try audiosession.setactive(true, with: .notifyothersondeactivation)      recognitionrequest = sfspeechaudiobufferrecognitionrequest()      guard let inputnode = audioengine.inputnode else {         print("there error in audioengine.inputnode")         fatalerror("audio engine has no input node")     }      guard let recognitionrequest = recognitionrequest else {         fatalerror("unable create sfspeechaudiobufferrecognitionrequest object")     }      // configure request results returned before audio recording finished     recognitionrequest.shouldreportpartialresults = true      // recognition task represents speech recognition session.     // keep reference task can cancelled.     recognitiontask = recognizer.recognitiontask(with: recognitionrequest) { result, error in          func finalizeresult() {             self.audioengine.stop()             inputnode.removetap(onbus: 0)             self.recognitionrequest = nil             self.recognitiontask = nil         }          guard error == nil else {             finalizeresult()             return         }          if !(result?.isfinal)! {              guard self.isrecognizing else {                 return             }                  // process partial result                 self.processrecognition(result: result)              } else {             finalizeresult()         }               }      let recordingformat = inputnode.outputformat(forbus: 0)     inputnode.installtap(onbus: 0, buffersize: 1024, format: recordingformat) { (buffer, when) in         self.recognitionrequest?.append(buffer)     }      audioengine.prepare()      {         try audioengine.start()     } catch let error nserror {         print("audio engine start error=\(error)")     } }

to cancel or stop @ point use these methods:

@objc func stoprecording() {     isrecognizing = false     audioengine.stop()     recognitionrequest?.endaudio()     self.delegate?.recognitionfinished() }  func cancelrecording() {     isrecognizing = false     audioengine.stop()     recognitiontask?.cancel()     self.delegate?.recognitionfinished() }

i setup button trigger speech recognition , tie recordspeech(). setup button , tie stoprecording(). when user stops request, result?.isfinal true , know final text first input. user use speech input again second set of speech.

most of code came 2016 wwdc session on speech recognition can find here:

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
