In android, user can switch other TTS engine to change option of Voice Setting and Language for the inputed text.There's a case that changing Voice Setting and Language will depend on the installed TTS engine.

EasyTTSUtil.Initialize(language, engine);
language - use the ISO 639-1 language code.
engine - is the package name of the installed TTS engine.​

EasyTTSUtil.GetEnginePkgArray() - in this method, you can get the list of TTS names that are installed in device.​

In addition, a method that opens a screen for voice setting of the device:

EasyTTSUtil.OpenTTSSetting() - this can also be used, please use if tis needed.​

6.     private string engineName = "";
7.     private string enginePkg ="";
8.  
9.     void OnGUI ()
10.     {
11.         stringToEdit = GUI.TextField (new Rect (Screen.width / 2 - 100, Screen.height / 2 - 100, 200, 50),

21.         }

28.             selected = GUILayout.SelectionGrid (selected, nameArray, 1);
29.             if (selected != -1) {
30.  
31.                 string[] pkgArray = EasyTTSUtil.GetEnginePkgArray ();
32.                 enginePkg = pkgArray [selected];
33.                 engineName = nameArray [selected];
34.                 EasyTTSUtil.Initialize(EasyTTSUtil.UnitedStates,enginePkg);
35.                 selecting = false;
36.             }

Hi FreCre,


I have been looking at releasing a game with speech on Android/iOS, and it's great to see someone wrapping the native capabilities. Can you please explain what the steps are to deploy a game with your asset. E.g. does the user need to install any libraries before they can play? Does speech playback pause the game? stop it? take it to a native screen etc.?

Thanks

 

Hi FreCre,

Thanks for the nice plugin.
Is there a way to get female voices on ios and android ?

 

Is there anyway to control the volume of the voice?

 

Wondering the same thing as the others. Is there a way to change the voice and volume of the voice? Thanks.

 

I just update unity to 5.2.3 and now the voice speaks really slowly. This used to work great on 5.1 but now it sounds terrible. Is there anyway to change the speed that it speaks?
I tried changing the siri speed settings on the iPhone/ipad but that didn't have any affect.
Thanks

 

Hi ,

Can i use this commercially for my app ? and is this plugin use Internet for its working ?

thank you

 

I just Updated my xcode to 7.2 and now the voice speaks really slowly. This used to work great on Xcode 6.3 but now it sounds terrible. Is there anyway to change the speed that it speaks?

 

is there a way I can check if the audio stops?

 

Hi,

I have been using your asset for a while, its very nice , but i want to know if is it possible to get a phonetic pronunciation of the letters instead of the name.

Thank you

 

You need to open Assets/Plugins/iOS/EasyTTSUtil.mm and increase the utterance.rate value. I put it to 0.4f.

 

Hello All,

Please help me to sort this issue out

 

Is there any way to determine whether the voice is done speaking?
On iOS, there are callback delegates such as they are explained here:

http://stackoverflow.com/questions/...zer-didfinishspeechutterance-not-being-called
and
http://nshipster.com/avspeechsynthesizer/

But I don't know how to modify the code to make them work.
Any help would be much appreciated.

 

Is the plugin working on iOS 11?

 

Plugin does not work. Unity 2017.1 iOS 11.4 and publisher URL is broken.
Can anybody help me?

 

is it possible to save the speech as an audio file during gameplay?

 

Hey there,

This tool seems great. I am thinking about getting it, but I have a few questions:
> Does it work offline?
> Which languages can be chosen?

Thanks!

 

Is it possible to wait for the speech to end? Is there an API to check if the speech has ended?

 

I've been using this plugin for some time and it has always worked well. However, today I discovered it has stopped working on iOS - apps which are already live on the App Store and have always worked correctly, now don't speak when supposed to even though we haven't updated them or changed anything. I've tested on both iOS 13 and 14 and there is no speech on either now. I have tested some apps by other developers that use text to speech with the same voices as far as I can tell (presumably using AVSpeechSynthesizer coded natively rather than via this plugin) and they all still work fine. Is this a known issue anybody else has seen?

 

I'm using this on Unity 2020.01 and I can't seem to make it work

 

Same here I am using 2019 LTS

 

Any plan to make it work with 2020.1 ? If not, please write it on the product description in order people don't buy it anymore

 

Does it work on Quest2?

 

Is it working with Unity 2020.3.6f1 and on Android 11?
