Can you hear me now? Move over Siri, here comes an army of speech-enabled mobile applications on Windows Phone. Mobile applications are not always easy to work with due to the small screen and small on-screen keyboard. Using our voice is a natural form of communication amongst humans, and ever since 2001: A Space Odyssey, we’ve been dreaming of computers who can converse with us like HAL9000. Or maybe you’re part of the new generation of geeks dreaming of Cortana? Thanks to the new Microsoft SDKs for voice recognition and speech synthesis (aka text-to-speech), we are now several steps closer to this reality. This session explores the development techniques you can use to add voice recognition to your Windows Phone applications, including in-app commands, standard & custom grammars, and voice commands usable outside your app. We’ll also see how your apps can respond to the user via speech synthesis, opening-up a new world of hands-free scenarios. This reality is here, you’ll see actual live demos with speech and you can now learn how to do it.

  3. 3. Agenda • Speech on Windows Phone 8 • Speech synthesis • Controlling applications using speech • Voice command definition files • Building conversations • Selecting application entry points • Simple speech input • Speech input and grammars • Using Grammar Lists
  4. 4. Speech on Windows Phone 8
  5. 5. Windows Phone Speech Support • Windows Phone 7.x had voice support built into the operating system • Programs and phone features could be started by voice commands e.g “Start MyApp” • Incoming SMS messages could be read to the user • The user could compose and send SMS messages • Windows Phone 8 builds on this to allow applications to make use of speech • Applications can speak messages using the Speech Synthesis feature • Applications can be started and given commands • Applications can accept commands using voice input • Speech recognition requires an internet connection, but Speech Synthesis does not
  6. 6. Speech Synthesis
  7. 7. Enabling Speech Synthesis • If an application wishes to use speech output the ID_CAP_SPEECH_RECOGNITION capability must be enabled in WMAppManifest.xml • The application can also reference the Synthesis namespace using Windows.Phone.Speech.Synthesis;
  8. 8. Simple Speech async void CheeseLiker() { SpeechSynthesizer synth = new SpeechSynthesizer(); await synth.SpeakTextAsync("I like cheese."); } • The SpeechSynthesizer class provides a simple way to produce speech • The SpeakTextAsync method speaks the content of the string using the default voice • Note that the method is an asynchronous one, so the calling method must use the async modifier • Speech output does not require a network connection
  9. 9. Selecting a language // Query for a voice that speaks French. var frenchVoices = from voice in InstalledVoices.All where voice.Language == "fr-FR" select voice; // Set the voice as identified by the query. synth.SetVoice(frenchVoices.ElementAt(0)); • The default speaking voice is selected automatically from the locale set for the phone • The InstalledVoices class provides a list of all the voices available on the phone • The above code selects a French voice
  10. 10. Demo 1: Speech Synthesis and Voice Selection talk2me - http://bit.ly/wpt2m
  11. 11. Speech Synthesis Markup Language <?xml version="1.0" encoding="ISO-8859-1"?> <speak version="1.0" xmlns=http://www.w3.org/2001/10/synthesis xml:lang="en-US"> <p> Your <say-as interpret-as="ordinal">1st</say-as> request was for <say-as interpret-as="cardinal">1</say-as> room on <say-as interpret-as="date" format="mdy">10/19/2010</say-as> , arriving at <say-as interpret-as="time" format="hms12">12:35pm</say-as>. </p> </speak> • You can use Speech Synthesis Markup Language (SSML) to control the spoken output • Change the voice, pitch, rate, volume, pronunciation and other characteristics • Also allows the inclusion of audio files into the spoken output • You can also use the Speech synthesizer to speak the contents of a file
  12. 12. Controlling Applications using Voice Commands
  13. 13. Application Launching using Voice command • The Voice Command feature of Windows Phone 7 allowed users to start applications • In Windows Phone 8 the feature has been expanded to allow the user to request data from the application in the start command • The data will allow a particular application page to be selected when the program starts and can also pass request information to that page • To start using Voice Commands you must Create a Voice Command Definition (VCD) file that defines all the spoken commands • The application then calls a method to register the words and phrases the first time it is run
  14. 14. The Fortune Teller Program • The Fortune Teller program will tell your future • You can ask it questions and it will display replies • It could also speak them • Some of the spoken commands activate different pages of the application and others are processed by the application when it starts running
  15. 15. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the “money” question: “Fortune Teller Will I find money”
  16. 16. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the phrase the user says to trigger the command • All of the Fortune Teller commands start with this phrase
  17. 17. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is example text that will be displayed by the help for this app as an example of the commands the app supports
  18. 18. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the command name • This can be obtained from the URL by the application when it starts
  19. 19. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the example for this specific command
  20. 20. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the trigger phrase for this command • It can be a sequence of words • The user must prefix this sequence with the words “Fortune Teller”
  21. 21. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the phraselist for the command • The user can say any of the words in the phraselist to match this command • The application can determine the phrase used • The phraselist can be changed by the application dynamically
  22. 22. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the spoken feedback from the command • The feedback will insert the phrase item used to activate the command
  23. 23. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • This is the url for the page to be activated by the command • Commands can go to different pages, or all go to MainPage.xaml if required
  24. 24. The Voice Command Definition (VCD) file <CommandPrefix> Fortune Teller </CommandPrefix> <Example> Will I find money </Example> <Command Name="showMoney"> <Example> Will I find money </Example> <ListenFor> [Will I find] {futureMoney} </ListenFor> <Feedback> Showing {futureMoney} </Feedback> <Navigate Target="/money.xaml"/> </Command> <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> • These are the phrases that can be used at the end of the command • The application can modify the phrase list of a command dynamically • It could give movie times for films by name
  25. 25. Installing a Voice Command Definition (VCD) file async void setupVoiceCommands() { await VoiceCommandService.InstallCommandSetsFromFileAsync( new Uri("ms-appx:///VCDCommands.xml", UriKind.RelativeOrAbsolute)); } • The VCD file can be loaded from the application or from any URI • In this case it is just a file that has been added to the project and marked as Content • The VCD can also be changed by the application when it is running • The voice commands for an application are loaded into the voice command service when the application runs • The application must run at least once to configure the voice commands
  26. 26. Launching Your App With a Voice Command • If the user now presses and holds the Windows button, and says: Fortune Teller, Will I find gold? the Phone displays “Showing gold” • It then launches your app and navigates to the page associated with this command, which is /Money.xaml • The query string passed to the page looks like this: "/?voiceCommandName=showMoney&futureMoney=gold&reco=Fortune%20Teller%Will%20I%20find%20gold" Command Name Phaselist Name Recognized phrase Whole phrase as it was recognized
  27. 27. Handling Voice Commands if (e.NavigationMode == System.Windows.Navigation.NavigationMode.New) { if (NavigationContext.QueryString.ContainsKey("voiceCommandName")) { string command = NavigationContext.QueryString["voiceCommandName"]; switch command) { case "tellJoke": messageTextBlock.Text = "Insert really funny joke here"; break; // Add cases for other commands. default: messageTextBlock.Text = "Sorry, what you said makes no sense."; break; } } } • This code runs in the OnNavigatedTo method of a target page • Can also check for the voice command phrase that was used
  28. 28. Identifying phrases <PhraseList Label="futureMoney"> <Item> money </Item> <Item> riches </Item> <Item> gold </Item> </PhraseList> string moneyPhrase = NavigationContext.QueryString["futureMoney"]; • The navigation context can be queried to determine the phrase used to trigger the navigation • In this case the program is selecting between the phrase used in the “riches” question
  29. 29. Demo 2: Fortune Teller
  30. 30. Modifying the phrase list VoiceCommandSet fortuneVcs = VoiceCommandService.InstalledCommandSets["en-US"]; await fortuneVcs.UpdatePhraseListAsync("futureMoney", new string[] { "money", "cash", “millions", “piles of dough" }); • An application can modify a phrase list when it is running • It cannot add new commands however • This would allow a program to implement behaviours such as: “Movie Planner tell me showings for Batman”
  31. 31. Simple Speech Input
  32. 32. Recognizing Free Speech • A Windows Phone application can recognize words and phrases and pass them to your program • From my experiments it seems quite reliable • Note that a network connection is required for this feature if you use the generic dictation grammar • Your application can just use the speech string directly • The standard “Listening” interface is displayed over your application
  33. 33. Simple Speech Recognition SpeechRecognizerUI recoWithUI; async private void ListenButton_Click(object sender, RoutedEventArgs e) { this.recoWithUI = new SpeechRecognizerUI(); SpeechRecognitionUIResult recoResult = await recoWithUI.RecognizeWithUIAsync(); if ( recoResult.ResultStatus == SpeechRecognitionUIStatus.Succeeded ) MessageBox.Show(string.Format("You said {0}.", recoResult.RecognitionResult.Text)); } • The above method checks for a successful response • By default the system uses the language settings on the Phone
  34. 34. Customizing Speech Recognition • InitialSilenceTimeout • The time that the speech recognizer will wait until it hears speech • The default setting is 5 seconds • BabbleTimeout • The time that the speech recognizer will listen while it hears background noise • The default setting is 0 seconds (the feature is not activated) • EndSilenceTimeout • The time interval during which the speech recognizer will wait before finalizing the recognition operation • The default setting is 150 milliseconds
  35. 35. Customizing Speech Recognition recoWithUI.Settings.ReadoutEnabled = false; // don't read the saying back recoWithUI.Settings.ShowConfirmation = false; // don't show the confirmation recoWithUI.Recognizer.Settings.InitialSilenceTimeout = TimeSpan.FromSeconds(6.0); recoWithUI.Recognizer.Settings.BabbleTimeout = TimeSpan.FromSeconds(4.0); recoWithUI.Recognizer.Settings.EndSilenceTimeout = TimeSpan.FromSeconds(1.2); • A program can also select whether or not the speech recognition echoes back the user input and displays it in a message box • The code above also sets timeout values
  36. 36. Handling Errors recoWithUI.Recognizer.AudioProblemOccurred +=Recognizer_AudioProblemOccurred; recoWithUI.Recognizer.AudioCaptureStateChanged += Recognizer_AudioCaptureStateChanged; ... void Recognizer_AudioProblemOccurred(SpeechRecognizer sender, SpeechAudioProblemOccurredEventArgs args) { MessageBox.Show("PLease speak more clearly"); } • An application can bind to events which indicate problems with the audio input • There is also an event fired when the state of the capture changes
  37. 37. Using Grammars
  38. 38. Grammars and Speech input • The simple speech recognition we have seen so far uses the “Short Dictation” grammar which just captures the text and returns it to the application • You can add your own grammars that will structure the conversation between the user and the application • Grammars can be created using the Speech Recognition Grammar Specification (SRGS) Version 1.0 and stored as XML files loaded when the application runs • This is a little complex, but worth the effort if you want to create applications with rich language interaction with the user • If the application just needs to identify particular commands you can use a grammar list to achieve this • Custom grammars can be handled on the client without any network access
  39. 39. Using Grammar Lists string [] strengthNames = { "weak", "mild", "medium", "strong", "english"}; recoWithUI.Recognizer.Grammars.AddGrammarFromList("cheeseStrength", strengthNames); • To create a Grammar List an application defines an array of strings that form the words in the list • The Grammar can then be added to the recognizer and given a name • Multiple grammar lists can be added to a grammar recognizer • The recognizer will now resolve any of the words in the lists that have been supplied
  40. 40. Enabling and Disabling Grammar Lists recoWithUI.Settings.ListenText = "How strong do you like your cheese?"; recoWithUI.Recognizer.Grammars["cheeseStrength"].Enabled = true; SpeechRecognitionUIResult recoResult = await recoWithUI.RecognizeWithUIAsync(); • An application can enable or disable particular grammars before a recognition action • It is also possible to set relative weightings of grammar lists • The text displayed as part of the listen operation can also be set, as shown above
  41. 41. Determining the confidence in the result SpeechRecognitionUIResult recoResult = await recoWithUI.RecognizeWithUIAsync(); if ( recoResult.RecognitionResult.TextConfidence == SpeechRecognitionConfidence.High ) { // select cheese based on strength value } • An application can determine the confidence that the speech system has in the result that was obtained • Result values are High, Medium, Low, Rejected
  42. 42. Matching Multiple Grammars var alternatives = recoResult.RecognitionResult.GetAlternates(3); • If the spoken input matches multiple grammars a program can obtain a list of the alternative results using recoResult.RecognitionResult.GetAlternatives • The list is supplied in order of confidence • The application can then determine the best fit from the context of the voice request • This list is also provided if the request used a more complex grammar
  43. 43. Profanity • Words that are recognised as profanities are not displayed in the response from a recognizer command • The speech system will also not repeat them • They are enclosed in <Profanity> </Profanity> when supplied to the program that receives the speech data
  44. 44. Summary • Applications in Windows Phone 8 can use speech generation and recognition to interact with users • Applications can produce speech output from text files which can be marked up with Speech Synthesis Markup Language (SSML) to include sound files • Applications can be started and provided with initial commands by registering a Voice Command Definition File with the Windows Phone • The commands can be picked up when a page is loaded, or the commands specify a particular page to load • An application can modify the phrase part of a command to change the activation commands • Applications can recognise speech using complex grammars or simple word lists
