Android Tutorial Android Text To Speech example

[pmsmc]

Thanks Erel, going to try that,
and what about the TTS error, after I use VR ?

 

[pmsmc]

I get this error
java.lang.RuntimeException: Method: IsSpeaking not found in: android.speech.tts.TextToSpeech

 

[Erel]

It should be isSpeaking not IsSpeaking.

 

[pmsmc]

thanks Erel, you're the man

I´m using the TTS library in my program but it lock the software for about 3 seconds until is ready.
I don´t need it to run the program just in some cases that the user press to listen a contact name.
I tried to load the library in a thread but still lock the program for 3 seconds.
There is any other way to load in background ?

<code>
If TTS1.IsInitialized = False Then
Dim args(0) As Object
Thread_TTS.Initialise("Thread_TTS")
Thread_TTS.Name = "Thread TTS"
Thread_TTS.Priority = Thread_TTS.MinPriority
Thread_TTS.Start(Me, "threadSub_1", args) 'o nome da thread tem que ter undescore
End If

Sub threadSub_1
If TTS1.IsInitialized = False Then
TTS1.Initialize("TTS1")
End If
end sub
</code>

 

[Erel]

It should be [ code ] (without the spaces) instead of <code>.

You don't need to use the Threading library. Are you sure that the app is freezes until the Ready event is fired?

The initialization process should happen in the background.

I build a list with received calls and without loading the library just after the program starts I can scroll the list, but when I initialize the library the scroll starts after 3 seconds

 

[Humberto]

Erel
I put the software in "Share your creation" and you can download from Play Store.
Now, for default, it is disabled the option to talk the contact and receveid calls but you can enable in configuration favorites sound and Register Sound.
You will be able to see the difference between load the library and not.
Ypu must change the language

 

[Erel]

Please try to reproduce it in a very simple project and see if it happens too.

 

[Humberto]

I wrote I project that build a list view with the calls received and if I load the TTS library still take more than 3 seconds to be able to scroll the list.
If I don´t load the library the scroll start instantly.

The english library took more time than portuguese library

 

[Erel]

Sorry but I don't have all the required libraries.

 

[Humberto]

Erel

there was some library that I didn´t used.

Now need just one library from outside please send your e-mail to send it . I already have the permission to send to you

 

[Erel]

Make a simple program that just initializes TTS and test it. It is not possible for me to go over a large project. Sorry.

 

[Humberto]

Ok
Now just build a listview.
If I try to initialize a TTS I can not scroll the list just after start.

 

[Erel]

It is a mistake to set the language before TTS is initialized.

Test with this code:

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.

   Dim listView1 As ListView
End Sub

Sub Activity_Create(FirstTime As Boolean)
   'Do not forget to load the layout file created with the visual designer. For example:
   'Activity.LoadLayout("Main")
  listView1.Initialize("ListView1")
  For i = 1 To 300
  listView1.AddSingleLine("Item #" & i)
  Next
  Activity.AddView(listView1, 0, 0, 100%x, 100%y)
End Sub

Sub Activity_Resume
   If TTS1.IsInitialized = False Then
     TTS1.Initialize("TTS1")
   End If
End Sub

Sub TTS1_Ready (Success As Boolean)
   Log("ready")
   If Success  Then
'     TTS1.SpeechRate = 1
'     TTS1.Pitch = 2
     If TTS1.SetLanguage("en" , "") = False Then  'en.fr,de
       ToastMessageShow( "TTS library not found", True)
       Return
     End If
'para falar
'     TTS1.Speak(EditText1.Text, True)
   Else
     Msgbox("Error initializing TTS engine.", "")
   End If
End Sub

I wasn't able to reproduce it as it takes a few milliseconds for the Ready event to be raised.

 

[Humberto]

I tested, but still the same problem.

I put another LOG after the language setup and we can see that takes 4 to 5 seconds ( samsung galaxy S3 ) to do the setup and during that time the activity is locked

Sub TTS1_Ready (Success As Boolean)
   DateTime.DateFormat = "yyyyMMdd HH:mm:ss"
   Log("ready: " &  DateTime.Date(DateTime.Now))
   If Success  Then
'     TTS1.SpeechRate = 1
'     TTS1.Pitch = 2
     If TTS1.SetLanguage("en" , "") = False Then  'en.fr,de
       ToastMessageShow( "TTS library not found", True)
       Return
     End If
    Log("setlanguage: " &  DateTime.Date(DateTime.Now))

   Else
     Msgbox("Error initializing TTS engine.", "")
   End If

End Sub

There is anything to do ?

 

[Erel]

This is strange. I tested it on several devices and the ready event fires very quickly. It is impossible to see whether it is blocking anything or not.

I'm going over Android source code and it shouldn't block the main thread. Maybe there is some problem with the TTS engine and it blocks the whole process on your device.

 

[Humberto]

I Tested in LG -II dual chip ( android 4.12 same as Galaxy S3). if "IsFirst = True" takes almost 5 seconds between the messages, but if I call again and IsFirst = False then there is no difference between the messages.

In Galaxy S3 always takes 3 seconds between the messages ( "ready" and "setlanguage" Logs)

 

[Erel]

Have you tested whether the UI is active or not at that time?

 

[Humberto]

How can I do this?
