Maybe I'm expecting different behavior, but here is what I came across. I'm more than happy to fix the bug and create a pull request, but I wanted to make sure I was using it correctly.

Bug Information

Version Number of Plugin: 3.0.1.0
Device Tested On: Android Device (custom hardware)
Simulator Tested On: N/A
Version of VS: VS 2017
Version of Xamarin: Xamarin.Android projects v8.0.99.67

Steps to reproduce the Behavior

CrossTextToSpeech.Current.Dispose();
await CrossTextToSpeech.Current.Speak("Some text");

Expected Behavior

System speaks "Some text"

Actual Behavior

Error is thrown

Exception occured in TTS.Speak for direction text.: Object reference not set to an instance of an object.: at Plugin.TextToSpeech.TextToSpeech.Speak (System.Nullable`1[T] cancelToken) [0x000b0] in C:\projects\texttospeechplugin\src\TextToSpeech.Plugin.Android\TextToSpeech.cs:150

Code snippet

Believe the issue is here where "textToSpeech" is null

And in dispose it makes "textToSpeech" null, but doesn't set "initalized" back to false

Could you explain is there any possibility generate mp3 file from AVSpeechSynthesizer..

Hi James,

This is awesome plug-in, really simple and clean.
What I want to request is to allow a variable pause between two phrases.

Use case: I need to implement a read-aloud section (a paragraph of 3-10 lines) with pauses at some place.

What happens right now is, the plug-in reads the para is a somewhat "symmetrical" pattern.
I know there is a speakRate option however it is applied uniformly to the entire paragraph

Wouldn't it be nice, if you can come up with a small internal parser which reads some token like [3S] or ^2^ which would let the speaker engine pause momentarily.

For example:
var LongText = "Dorothy is a young girl who lives with her Aunt Em and Uncle Henry and her little dog Toto on a farm in the Kansas prairies. ^2^ One day, Dorothy and Toto are caught up in a cyclone that deposits her farmhouse into Munchkin Country in the magical Land of Oz. "

CrossTextToSpeech.Current.Speak(LongText,
pitch: (float)1.2,
speakRate: (float)1,
volume: (float)1.5,
crossLocale: locale);

as in the above example the speaker engine would wait for 2 seconds before speaking the second sentence.

Hope this is achievable and I am not asking too much. 👍

Steps to reproduce the Behavior

Simple call like below
await Plugin.TextToSpeech.CrossTextToSpeech.Current.Speak(textToSpeech, crossLocale: Settings.CurrentLocale, cancelToken: ct);

Expected Behavior

Actual Behavior

I am seeing exceptions in my app center as in the link. Do you have any idea what could be the reason? I dont have any steps to reproduce as I only see in the exception logs on production for some devices. I logged information only if device has Supported and it is always IsSupported=true

I just created a new Cross Platform Xamarin Project. I added the Xam.Plugins.TextToSpeech plugin to the solution which added it to the core project and all the platform projects (Droid, IOS, WPF & UWP). The project compiles fine and I am able to use the Plugin in the Android project and it works. I am however getting the above exception. This functionality is not implemented in the portable version of the assembly when I run the UWP project in the simulator. I've tried removing the nuget package from the UWP project then adding it back. I did this for individual project and then again for the entire solution, cleaning the project, deleting all the files under bin, rebuilding all several times but still get the same error. To investigate this I looked in the bin folders of the various projects to confirm which version of the plugin dll is being deployed for each project and what I found is that the same plugin dll which is deployed to the core project is what is deployed to the UWP and WPF projects. Same size, same timestamp. The one deployed to the android project is larger. I confirmed this several times after uninstalling and reinstalling the nuget package, cleaning and rebuilding all.

I was able to work around it by poking into the nuget package itself and copying the correct plugin dll to the bin\x86\debug folder to overwrite the stub dll and for it to actually work to the bin\x86\debug\AppX folder. This way the correct dll was deployed to the simulator and it worked.

However I know if I rebuilt the project again same thing would happen. The second thing I noticed in the package is that there is also no folder for WPF in the lib folder. All I saw were monoandroid71, netstandard1.0, netstandard2.0, uap10.0.15063, xamarinios10, xamarinmac20 and xamarintvos10. No WPF and what is deployed in the debug folder of the wpf project is the same stub dll deployed in the core project.

Is this a bug or am I doing something wrong.

Version Number of Plugin: Latest 2.0.0
Device Tested On: Android
Simulator Tested On: Android

Expected Behavior

All length of text that is passes

Actual Behavior

Fails silently

Steps to reproduce the Behavior

Send a long string over the limit.

Please fill out either the bug or feature request section and remove whatever section you are not using.

Feature Request:

I don't know if this can be done or not. If it can be done, please guide me.
But, it would be nice to be able to choose the Speech Engine and a locale of our choice.

I found that locale can be set, but I couldn't get it working. I wanted to set "en_IN" as the locale to be used. how do I do that?

In Xamarin Forms the plugin is working on Windows Phone, and Desktop.
On Android, it fails with Null Exception Java Class not Found. (Debugging is turned off, I have no other diagnostics save the exception.)

I am using the simple call:

await CrossTextToSpeech.Current.Speak("Text to speak");

Please fill out either the bug or feature request section and remove whatever section you are not using.

Bug

Version Number of Plugin: 2.0.0
Device Tested On: Samsung Galaxy S7 Edge
Simulator Tested On: Visual Studio Emulator for Android, Similar to Samsung Galaxy S5, Sony Experia Z

Expected Behavior

Should say Arabic words in Text to Speech functionality

Actual Behavior

Not saying Arabic words. It doesn't say anything, just a very short beep. I haven't tried it on iOS yet so not sure if it works there or not.

Steps to reproduce the Behavior

I used the following code in a Xamarin.Forms project class:

Plugin.TextToSpeech.Abstractions.CrossLocale locale = new Plugin.TextToSpeech.Abstractions.CrossLocale();
locale.Language = "ar";
locale.Country = "eg";
Plugin.TextToSpeech.CrossTextToSpeech.Current.Speak("هيا بنا نلعب", false, locale);

Please note that I tried it with and without setting the locale language and country variables.

Steps to reproduce the Behavior

Expected Behavior

The text to speech will work inside the App.xaml.cs OnSleep() method

Actual Behavior

It doesn't work after I put inside the OnSleep() method

Code snippet

protected override void OnSleep()
{
    // Handle when your app sleeps
    CrossTextToSpeech.Current.Speak("My Text To Speech Sample");    
}
### ScreenShot
none

The title is fairly self-explanatory, I think. Eventually I want to be able to use alternate voices, and while it looks like I might be able to sneak it in through the existing crossLocale parameter (given the Android docs, assuming API 20+), I'd have to wrangle with it a bit to get there.

Would there be interest if I forked out a branch to try implementing that myself?

Bug Information

No sound on physical iPhone 7 running IOS 11.4.1

Version Number of Plugin: 4.1.0.1-beta (and prior release version as well)
Device Tested On: iPad and iPhone, Working on iPad, not iPhone. Could be iOS 11.4.1 issue.
Simulator Tested On: iPad and iPhone 7 version 11.4

Version of VS: VS for Mac 7.6
Version of Xamarin: Xamarin.IOS 11.14

Steps to reproduce the Behavior

Installed nuget package and created simple app to play text to speech.

Code snippet

CrossTextToSpeech.Current.Speak("blah")

Copied from: jamesmontemagno/Xamarin.Plugins#194

Feature Request:

Android allows a TTS Engine (string) to be passed in to the TextToSpeech constructor, it would be nice to have an additional flag for Android to set the package name that is part of the constructor:

See documentation: [Docs](http://developer.android.com/reference/android/speech/tts/TextToSpeech.html#TextToSpeech%28android.content.Context, android.speech.tts.TextToSpeech.OnInitListener, java.lang.String%29)

Modification to allow a TTS engine selection. For Android, generally done through the constructor.

    public void Init()
    {
        Console.WriteLine("Current version: " + (int)global::Android.OS.Build.VERSION.SdkInt);
        Android.Util.Log.Info("CrossTTS", "Current version: " + (int)global::Android.OS.Build.VERSION.SdkInt);

        textToSpeech = new Android.Speech.Tts.TextToSpeech(Application.Context, this,<<TTS ENGINE>>);
    }

Idea would just to have a string on the Android implementation that can be set and modified.

Obviously you're hard at work on this one! Good timing, by me; it's an excellent fit for my project.

But Intellisense is leaving me rather puzzled, because the method signature it has for Speak() isn't the same as the method signature for the version you've got up here in /src.

I'm trying to write a wrapper for your code which will let me integrate its timings with the rest of the app, so the question of how I access cancellations is of interest to me. And I can work with either - but I gotta have the information on what's up! The docstring is (IMO) not as helpful as it could be... do you mean "True if you want to chain them together, false if you want the new one to cancel the current one"?

Does that imply that you're unifying Task and non-Task cancellation options into that simple boolean? Not a bad idea, although in that case a convenience function of "TTS.StopSpeaking" which cancels without starting a fresh one (possibly with the use of playSilentUtterance, at least on that platform) might be a nice feature to at least pencil in.

(Currently I'm restricted to Android-only but I'm trying to use as many cross-platform components as possible. Amusingly, I arrived at your TTS and Rendy Del Rosario's Device Motion via entirely separate search paths. Both are lovely!)

I need to get Locales synchronously because I am running in a method synchronously in following order

• get locale

  This was working fine in version 2 but in version 3, It returns a task and I dont understand the reason why I cant run it as synchronously , I tried all the possible methods to wait for result but it looks like it doesnt work. Both below simply should work but when I debug, they dont execute, it seems like getting deadlock. Can you please advise?

It would be nice to get a notification/event that I can subscribe to when speaking has finished.

I've searched for quite a wile to see if these functions are already built into this amazing TTS plugin. I have not been able to find its implementation anywhere. Is this something that can be done with this current plugin? And if not, would the creator consider adding this functionality or suggest a way I can get a similar result?
Thanks

When calling GetInstalledLanguages() for the first time, the plugin always detects that the TextToSpeech has not been initialized yet leading to a wrong list of installed languages with a lot of languages which does not supported by TextToSpeech.

• Root cause:
  The "initialized = true;" line in OnInit() method is put bellow the line "initTcs.TrySetResult(true);".

• Solution:
  Re-order the two lines above.

Hi @jamesmontemagno

I am getting following error while executing await CrossTextToSpeech.Current.Speak(text);. Am I missing anything?

I tried to set as below and tested with german and spanish languages but everytime, I get English accent. I compared language and displayname from the avilable list and they are set correctly for both languages.
I expect native speech. Do I understand this wrong? Do i do something wrong?

  var crosslocale = new Plugin.TextToSpeech.Abstractions.CrossLocale()
            {
                 Language = CurrentCultureInfo.TwoLetterISOLanguageName,

 Plugin.TextToSpeech.CrossTextToSpeech.Current.Speak(text, crossLocale: crosslocale)

Crashes sometimes occur in case of cancellation when several requests are pending.

Following update corrects the issue:
In the Speak(...) function (TextToSpeech.Plugin.iOS/TextToSpeech.cs line 50), just after:
await semaphore.WaitAsync(cancelToken);
Add:
cancelToken.ThrowIfCancellationRequested();

(Before calling: await SpeakUtterance(speechUtterance, cancelToken);)

Bug Information

Version Number of Plugin: >= v3.0.1
Simulator Tested On: Oreo AVD
Version of VS: 15.6.2

Steps to reproduce the Behavior

Craft a text with exactly MaxSpeechInputLength characters and call Speek()

Expected Behavior

should synthesize text

Actual Behavior

Does not synthesize text nor does it throw exception

It works fine in ios, but the moment we change voices from the device setting for ios. still, it plays for the same voice. Can you just confirm the behavior?

Bug

Version Number of Plugin: 2.0.0
Device Tested On: OnePlus Two
Simulator Tested On: -

Expected Behavior

being able to await Speak()

Actual Behavior

Steps to reproduce the Behavior

Add the plugin version 2.0.0 from nuget
Make an async method and use Speak() like in the getting started:
await CrossTextToSpeech.Current.Speak("Text to speak");

It's really weird, as i can see on the source here on github, that ITextToSpeech Speak() returns a Task, however when i check the code it says void:

Any help is appreciated! I might just be failing ;)

Bug Information

Version Number of Plugin: 3.0.1
Device Tested On: Sony Xperia Z3 Android 6.0.1
Simulator Tested On:
Version of VS: 2017
Version of Xamarin: Latest
Versions of other things you are using:

Steps to reproduce the Behavior

If I understand correctly we have to query for selected locale in android as in the given sample

           ```
         languageButton.Text = selected;

			if (Device.RuntimePlatform == Device.Android)
				locale = locales.FirstOrDefault(l => l.ToString() == selected);
			else
				locale = new CrossLocale { Language = selected };//fine for iOS/WP

So in UWP and IOS, it is enough to pass language code.  

### Expected Behavior

Is there a possibility to use have default as English, in any case, if CrossLocales is null or queried CrossLocale  not found. I believe this was behavior in earlier version. 

### Actual Behavior

I had mistake and CrossLocale was returning nothing in Android, application was doing nothing (i didnt event get exception.
