free runtime text to speech plugin (windows only)

mgear · December 20, 2019, 3:09pm

needed a quick tts plugin for a small game thingy, so gobbled this together :
https://github.com/unitycoder/UnityRuntimeTextToSpeech

its not pretty (also editor can silently crash when exit, but works fine otherwise so far),
but its free and standalone (doesnt use windows system voices etc).

there is link to example voice in the readme.

NativeDllException: Could not load DLL "libespeak-ng.dll" at path

in Windows 7 Unity 2020 alpha

mgear · January 26, 2020, 8:44am

tested on 2020 win10, works here… not sure what could cause that.
(and you cloned the whole project and have the dll in the root ?)

id0 · January 26, 2020, 9:06am

Yes, just download and open, not change anything. When I press “play” I got this errors:

hmm… i’ll test on another pc tomorrow. (if its related to something i have installed on this pc, i did install the espeak last time)

mgear · January 27, 2020, 6:28am

works on another pc (win10) and just noticed that the espeak page says:
“minimum version : Windows 8”, so it must be that.

Too bad. I would like my androids talking…

mgear · January 27, 2020, 3:14pm

for android can find other plugins in asset store, or make your own android plugin:

No, no, true androids, robots in my game Oh well…

i’d probably try with SSML if it allows setting lang, need to enable this,
https://github.com/unitycoder/UnityRuntimeTextToSpeech/blob/master/Assets/Scripts/Speech.cs#L117
and then https://github.com/unitycoder/UnityRuntimeTextToSpeech/wiki/Using-SSML

Been playing with this and it works great on Windows 10 so far. I’m having trouble with SSML tags though. If I pass in a string to Say() with something like for example, it reads out the content of the tag. Do you have any examples handy of how to format the SSML?

mgear · October 3, 2020, 12:43pm

ssml is not enabled by default, here:

github.com

unitycoder/UnityRuntimeTextToSpeech/blob/master/Assets/Scripts/Speech.cs#L117


      
                  message_waited_for = "";
                  callback_waited_for = null;
              }
          } else if (HasMessage()) {
              try
              {
                  IncomingMessage msg = PopMessage();
                  switch(msg.type) { 
                      case IncomingMessageType.Say:
                          Client.Speak(msg.message);
                          //Client.SpeakSSML(msg);
          
                          message_waited_for = msg.message;
                          callback_waited_for = msg.callback;
                          waiting_for_line = true;
                          break;
                      case IncomingMessageType.SetPitch:
                          Client.SetPitch(msg.param1);
                          break;
                      case IncomingMessageType.SetRange:
                          Client.SetRange(msg.param1);

Hi,
I’m pretty new to Unity. I try to import your plugin with the package manager but nothing happen. Can you tell me how do you import it in a project pls?

I try to check it to test if it work for a small app with WebGL.

Tank you

mgear · May 20, 2021, 11:47am

need to download manually, its not in package format.

but its desktop only, not webgl.
asset store has some TTS plugins that could work, maybe this or others

rubenbr83 · June 25, 2021, 8:22am

Im new on unity. it is possible to change the language? How?

mgear · June 25, 2021, 3:26pm

Any chance on getting this to run on Android? I’m looking to add TTS to Quest 2 and Oculus decided to strip Pico TTS from the device. So most of the assets in the Unity store don’t work as they rely on native features. I’ve tested web APIs like goolge to get TTS and they work, but I can’t rely on internet so I want an embedded solution. Thoughts? Also, thanks for the work!

mgear · January 22, 2022, 8:18pm

at least i don’t know how…

can check if any of these alternatives would work,
