Detailed Description

SpeechRecognizer icon

Use a SpeechRecognizer component to listen to the user speaking and convert the spoken sound into text using the device's speech recognition feature.

@internaldoc Component for using the built in VoiceRecognizer to convert speech to text. For more details, please see: http://developer.android.com/reference/android/speech/RecognizerIntent.html

Definition at line 47 of file SpeechRecognizer.java.

Constructor & Destructor Documentation

◆ SpeechRecognizer()

com.google.appinventor.components.runtime.SpeechRecognizer.SpeechRecognizer ( ComponentContainer  container)

Creates a SpeechRecognizer component.

Parameters
containercontainer, component will be placed in

Definition at line 63 of file SpeechRecognizer.java.

Member Function Documentation

◆ AfterGettingText()

void com.google.appinventor.components.runtime.SpeechRecognizer.AfterGettingText ( String  result,
boolean  partial 
)

Simple event to raise after the SpeechRecognizer has recognized speech. If UseLegacy(boolean) is true{:.logic.block}, then this event will only happen once at the very end of the recognition. If UseLegacy(boolean) is false{:.logic.block}, then this event will run multiple times as the SpeechRecognizer incrementally recognizes speech. In this case, partial will be true{:.logic.block} until the recognized speech has been finalized (e.g., the user has stopped speaking), in which case partial will be false{:.logic.block}.

Definition at line 148 of file SpeechRecognizer.java.

◆ BeforeGettingText()

void com.google.appinventor.components.runtime.SpeechRecognizer.BeforeGettingText ( )

Simple event to raise when the SpeechRecognizer is invoked but before its activity is started.

Definition at line 134 of file SpeechRecognizer.java.

◆ GetText()

void com.google.appinventor.components.runtime.SpeechRecognizer.GetText ( )

Asks the user to speak, and converts the speech to text. Signals the AfterGettingText(String, boolean) event when the result is available.

Definition at line 88 of file SpeechRecognizer.java.

◆ onClear()

void com.google.appinventor.components.runtime.SpeechRecognizer.onClear ( )

◆ onError()

void com.google.appinventor.components.runtime.SpeechRecognizer.onError ( int  errorNumber)

Method from SpeechListener interface.

Implements com.google.appinventor.components.runtime.SpeechListener.

Definition at line 174 of file SpeechRecognizer.java.

◆ onPartialResult()

void com.google.appinventor.components.runtime.SpeechRecognizer.onPartialResult ( String  text)

Method from SpeechListener interface.

Implements com.google.appinventor.components.runtime.SpeechListener.

Definition at line 156 of file SpeechRecognizer.java.

◆ onResult()

void com.google.appinventor.components.runtime.SpeechRecognizer.onResult ( String  text)

Method from SpeechListener interface.

Implements com.google.appinventor.components.runtime.SpeechListener.

Definition at line 165 of file SpeechRecognizer.java.

◆ Result()

String com.google.appinventor.components.runtime.SpeechRecognizer.Result ( )

Returns the last text produced by the recognizer.

Definition at line 79 of file SpeechRecognizer.java.

◆ Stop()

void com.google.appinventor.components.runtime.SpeechRecognizer.Stop ( )

Function used to forcefully stop listening speech in cases where SpeechRecognizer cannot stop automatically. This function works only when the UseLegacy(boolean) property is set to false{:.logic.block}.

Definition at line 123 of file SpeechRecognizer.java.

◆ UseLegacy() [1/2]

boolean com.google.appinventor.components.runtime.SpeechRecognizer.UseLegacy ( )

Definition at line 189 of file SpeechRecognizer.java.

◆ UseLegacy() [2/2]

void com.google.appinventor.components.runtime.SpeechRecognizer.UseLegacy ( boolean  useLegacy)

If true, a separate dialog is used to recognize speech (the default). If false, speech is recognized in the background and updates are received as it recognizes words. AfterGettingText(String, boolean) may get several calls with partial set to true{:.logic.block}. Once sufficient time has elapsed since the last utterance, or StopListening is called, the last string will be returned with partial set to false{:.logic.block} to indicate that it is the final recognized string and no more data will be provided until recognition is again started. See AfterGettingText(String, boolean) for more details on partial speech recognition.

Parameters
useLegacy
