Detailed Description

This abstracts out what a text to speech implementation needs to have. In particular we use this to enable having an implementation that uses the internal Android TextToSpeech library for post-Donut devices and uses an externally installed library for the earlier devices.

Member Function Documentation

isInitialized()

boolean com.google.appinventor.components.runtime.util.ITextToSpeech.isInitialized

(

)

Implemented in com.google.appinventor.components.runtime.util.ExternalTextToSpeech, and com.google.appinventor.components.runtime.util.InternalTextToSpeech.

isLanguageAvailable()

int com.google.appinventor.components.runtime.util.ITextToSpeech.isLanguageAvailable

(

Locale

loc

)

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

onDestroy()

void com.google.appinventor.components.runtime.util.ITextToSpeech.onDestroy

(

)

This will be called when the Activity is destroyed, to give us a chance to cleanup resources, if necessary.

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

onResume()

void com.google.appinventor.components.runtime.util.ITextToSpeech.onResume

(

)

This will be called when the Activity is resumed, to give us a chance to re-initialize resources, if necessary.

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

onStop()

void com.google.appinventor.components.runtime.util.ITextToSpeech.onStop

(

)

This will be called when the Activity is stopped, to give us a chance to cleanup resources, if necessary.

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

setPitch()

void com.google.appinventor.components.runtime.util.ITextToSpeech.setPitch

(

float

pitch

)

Sets the speech pitch for the TextToSpeech

Parameters

pitch

1.0 is the normal pitch, lower values lower the tone of the synthesized voice, greater values increase it.

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

setSpeechRate()

void com.google.appinventor.components.runtime.util.ITextToSpeech.setSpeechRate

(

float

speechRate

)

Sets the speech rate

Parameters

speechRate

Speech rate. 1.0 is the normal speech rate, lower values slow down the speech (0.5 is half the normal speech rate), greater values accelerate it (2.0 is twice the normal speech rate).

Implemented in com.google.appinventor.components.runtime.util.InternalTextToSpeech, and com.google.appinventor.components.runtime.util.ExternalTextToSpeech.

speak()

void com.google.appinventor.components.runtime.util.ITextToSpeech.speak	(	String	message,
		Locale	loc
	)

Speaks the given message corresponding to the language and country of the given locale.

Parameters

message	the message to speak
loc	the locale to use

Implemented in com.google.appinventor.components.runtime.util.ExternalTextToSpeech, and com.google.appinventor.components.runtime.util.InternalTextToSpeech.
