c# - 认知服务说话人识别问题

Question

我是 Azure 的新手，但我得到了以下任务，使用 Azure 认知服务说话人识别来确认说话人与已知或注册的声音相匹配。微软网站上有一篇文章，其中包含如何使用语音服务的示例，但是当我运行该示例时，它会在 SpeakerVerify 函数上停止，并且无法处理相似度得分结果（结果 = await speakerRecognizer.RecognizeOnceAsync (model)） . 一切都与 Azure 同步。请帮我找出问题所在。先感谢您。

抱歉，我没有重现您的错误。

我在官方文档中测试了代码，效果很好。 而且我还修改了您的代码，该代码停留在这一部分：

我发现唯一不同的是我们用result.RemainingEnrollmentsCount的，而你用result.RemainingEnrollmentsSpeechLength的。

尝试使用官方文档中的代码：

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using Microsoft.CognitiveServices.Speech;
using Microsoft.CognitiveServices.Speech.Audio;

namespace SpeakerRecog
{
    public class Program
    {

        public static async Task VerificationEnroll(SpeechConfig config, Dictionary<string, string> profileMapping)
        {
            using (var client = new VoiceProfileClient(config))
            using (var profile = await client.CreateProfileAsync(VoiceProfileType.TextDependentVerification, "en-us"))
            {
                using (var audioInput = AudioConfig.FromDefaultMicrophoneInput())
                //using (var audioInput = AudioConfig.FromWavFileInput("myVoiceIsMyPassportVerifyMe01.wav"))
                {
                    Console.WriteLine($"Enrolling profile id {profile.Id}.");
                    // give the profile a human-readable display name
                    profileMapping.Add(profile.Id, "Doris");

                    VoiceProfileEnrollmentResult result = null;

                    while (result is null || result.RemainingEnrollmentsCount > 0)
                    {
                        Console.WriteLine("Speak the passphrase, \"My voice is my passport, verify me.\"");
                        result = await client.EnrollProfileAsync(profile, audioInput);
                        Console.WriteLine($"Remaining enrollments needed: {result.RemainingEnrollmentsCount}");
                        Console.WriteLine("");
                    }

                    if (result.Reason == ResultReason.EnrolledVoiceProfile)

                    }
                }

            var result = await speakerRecognizer.RecognizeOnceAsync(model);
            Console.WriteLine($"Verified voice profile for speaker {profileMapping[result.ProfileId]}, score is {result.Score}");
        }

        static async Task Main(string[] args)
        {
            // replace with your own subscription key 
            string subscriptionKey = "subscriptionKey";
            string region = "westus";
            var config = SpeechConfig.FromSubscription(subscriptionKey, region);

            // persist profileMapping if you want to store a record of who the profile is
            var profileMapping = new Dictionary<string, string>();
            await VerificationEnroll(config, profileMapping);

            Console.ReadLine();
