Unity with azure speech sdk

Question

当我在unity上使用azure语音sdk时，当我在计算机上测试它时，它工作得很好，我可以说话，它可以正常识别和响应语音。

当我为Android和iOS构建时，它不起作用。在iOS和Android上，它都可以在不尝试识别任何东西的情况下提高识别点，如果我只是放一个来自sdk的简单语音，它也不会给出任何东西。

如何解决这个问题?

下面是在unity和windows build中工作的代码:

---------------------------------------------
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);  

在iOS上，它在控制台上给了我这个:

Answer 1

这个问题是由iOS和Android的配置问题引起的。查看android和iOS的配置文档。

有一个github的repo可以解决类似的问题。检查一次

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

iOS库将使用Objective - C开发并且不支持任何JavaScript库。同样，对于Android Cordova将用于处理JavaScript库。这两个是不支持每一个相对的平台。因此，请检查开发平台的配置以及支持的库语言。

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

Answer 2

您报告的问题(SPXERR_MIC_ERROR)表明您没有正确配置麦克风。你可以先尝试Unity快速启动https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/quickstart/csharp/unity/from-microphone，测试它在你的Android和iOS设备上的工作，然后将配置应用到你的应用程序。
