c# - 循环内的 SpeechSynthesizer 没有统一迭代

Question

我正在将代码从https://github.com/Azure-Samples/cognitive-services-speech-sdk/blob/master/quickstart/csharp/unity/text-to-speech/Assets/Scripts/HelloWorld.cs修改为让它从 1 计数到 10。虽然迭代在控制台中显示得很好，但系统只显示“十”。

我试图让它说“一”，“二”，“三”......“十”使用for循环。

我错过了什么？

using UnityEngine.UI;

public class HelloWorld : MonoBehaviour
{
    // Hook up the three properties below with a Text, InputField and Button object in your UI.
    public Text outputText;
    public InputField inputField;
    public Button speakButton;
    public AudioSource audioSource;

    private object threadLocker = new object();

    private SpeechConfig speechConfig;
    private SpeechSynthesizer synthesizer;


    public void ButtonClick()
    {

        // Starts speech synthesis, and returns after a single utterance is synthesized.
        for (int j = 1; j <= 10; j++)
        {
            Debug.Log("Iteration: " + j);


            using (var result = synthesizer.SpeakTextAsync(j.ToString()).Result)

            {
                // Checks result.
                if (result.Reason == ResultReason.SynthesizingAudioCompleted)
                {
                    var sampleCount = result.AudioData.Length / 2;
                    var audioData = new float[sampleCount];
                    for (var i = 0; i < sampleCount; ++i)
                    {
                        audioData[i] = (short)(result.AudioData[i * 2 + 1] << 8 | result.AudioData[i * 2]) / 32768.0F;
                    }

Answer 1

我最终做了以下事情，它按我想要的方式工作。基本上使按钮单击功能异步并等待合成器。

public async void ButtonClick()
    {
        Debug.Log("Button Pressed!");

        for (int j = 1; j <= 10; j++)
        {

            string newMessage = string.Empty;

            var config = SpeechConfig.FromSubscription("KEY", "northeurope");
            using var synthesizer = new SpeechSynthesizer(config);
            await synthesizer.SpeakTextAsync(j.ToString());

            } 
    }
