图灵聊天机器人API:

            logger.Error(ex, ex.Message);
            return "出错了";
        }
    }

微软语音合成API：

public class VoicesHelper
{
    private static readonly Logger logger = LogManager.GetCurrentClassLogger();

    private const string TOKEN_URI = "https://southeastasia.api.cognitive.microsoft.com/sts/v1.0/issuetoken";

            return "出错了";
        }
    }

    public static async Task RequestSSML(string authToken, string text, string fileName)
    {
        try
        {
            using (var httpClient = new HttpClient())

                var body = "<speak xmlns=\"http://www.w3.org/2001/10/synthesis\" xmlns:mstts=\"http://www.w3.org/2001/mstts\" version=\"1.0\" xml:lang=\"zh-CN\"><voice name=\"xixi\">" + text + "</voice></speak>";
                var request = new HttpRequestMessage()

        {
            logger.Error(ex, ex.Message);
        }
    }
}

调用这两个API：

[HttpPost]
public IActionResult Voices(Context context)
{
    logger.LogError(520, $"问：{ context.body}");
    var text = TulingHelper.RequestTuling(context.body).ConfigureAwait(false).GetAwaiter().GetResult();
    logger.LogError(521, $"答：{text}");

    var result = VoicesHelper.GetTokenAsync().ConfigureAwait(false).GetAwaiter();
    string token = result.GetResult();

    string fileName = $"/voiceswav/{Guid.NewGuid().ToString()}.wav";
    var task1 = VoicesHelper.RequestSSML(token, text, $"./wwwroot{fileName}");
    task1.ConfigureAwait(false).GetAwaiter().GetResult();
    return Ok(fileName);
}
