Unity with azure speech sdk

Question

When i am using the azure speech sdk on unity, when i test it on the computer it works fine, i can speak, it recognizes and responds in speech all normal.

When I build for Android and iOS it doesn't work. Both on iOS and Android it advances the recognition points without trying to recognize anything, if I just put a simple speech coming from the sdk it doesn't give anything either.

How can I resolve this problem?

Here's the code that works in unity and windows build:

---------------------------------------------
    void Start()
    {
        anim = gameObject.GetComponent<Animator>();

        var config = SpeechConfig.FromSubscription("xxxxxxxxxxxx", "northeurope");
     
        cred(config);
    }



 async Task cred(SpeechConfig config)
    { 
       texttest.GetComponent<Text>().text = config.ToString();

        var audioConfig = AudioConfig.FromDefaultMicrophoneInput();

        var synthesizer2 = new SpeechRecognizer(config, audioConfig);

        var result = await synthesizer2.RecognizeOnceAsync();

        var synthesizer = new SpeechSynthesizer(config);

            SynthesizeAudioAsync(config, synthesizer2, result);
    } 

  async Task SynthesizeAudioAsync(SpeechConfig config, SpeechRecognizer synthesizer2, SpeechRecognitionResult result)
    {
        texttest.GetComponent<Text>().text = "syn1 " + result.Text;

        OutputSpeechRecognitionResult(result);
        if (result.Reason == ResultReason.RecognizedSpeech)
            {
                if (result.Text == "xx" || result.Text == "xx" || result.Text == xx." || result.Text == "xx")
                {

                var synthesizer = new SpeechSynthesizer(config); 
  
                anim.Play("helloAll", 0, 0); 
                await synthesizer.SpeakTextAsync("Helloxx");
                chooseTopic(config,  synthesizer, result.Text);  

On iOS it gives me this in the console:

Answer 1

The issue was raised because of the configuration issues in iOS and Android. Check the documentation for configuration in android and iOS .

There is a github repo which works on the similar issue. Check it once.

https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/quickstart/csharp/unity/from-microphone

The iOS libraries will be developed using Objective - C and doesn't support any kind of JavaScript libraries. In the same way, for Android Cordova will be used to handle the JavaScript libraries. These two are non - supportable for each opposite platform. Hence, check with the configuration of the developing platform and also the supporting libraries language.

Cordova Platforms : android 7.1.4 ios 4.5.5
Ionic Framework : ionic-angular 3.9.2
iOS: Objective - C
