C#调用edge tts

### 如何在C#中使用Edge TTS API 为了在C#应用程序中集成Microsoft Edge的TTS(Text To Speech)功能，可以利用`System.Speech`命名空间中的类来实现基本的文字转语音功能。然而，对于更高级的功能以及更好的跨平台支持，推荐通过HTTP请求调用Azure Cognitive Services下的Text to Speech REST API。 下面是一个简单的例子展示如何发送HTTP POST请求到Azure Text to Speech服务并播放返回的声音文件： ```csharp using System; using System.Net.Http; using System.Text; public class Program { private static readonly string subscriptionKey = "your_subscription_key"; private static readonly string region = "your_region"; // e.g., westus public async Task SpeakAsync(string textToSpeak) { var url = $"https://{region}.tts.speech.microsoft.com/cognitiveservices/v1"; using (var client = new HttpClient()) { client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey); var requestBody = new StringBuilder(); requestBody.AppendLine("<speak version='1.0' xml:lang='en-US'>"); requestBody.AppendLine($"<voice xml:lang='en-US' name='en-US-JennyNeural'>{textToSpeak}</voice>"); requestBody.AppendLine("</speak>"); HttpContent content = new StringContent(requestBody.ToString(), Encoding.UTF8, "application/ssml+xml"); HttpResponseMessage responseMessage = await client.PostAsync(url, content); if(responseMessage.IsSuccessStatusCode){ byte[] audioBytes = await responseMessage.Content.ReadAsByteArrayAsync(); // Play or save the received audio bytes here. Console.WriteLine("Audio successfully generated."); } else { Console.WriteLine($"Error occurred while generating speech: {responseMessage.ReasonPhrase}"); } } } } ``` 此代码片段展示了创建一个异步方法`SpeakAsync`，它接受要转换成语音的字符串参数，并向指定区域的服务端点发起POST请求[^4]。需要注意的是，在实际应用之前应该替换掉示例中的订阅密钥(`subscriptionKey`)和地区名称(`region`)为自己的有效值。
