失敗 - 優文庫

我一直努力讓自己在如何使用波利（https://aws.amazon.com/polly/）失敗

我不想下載任何庫一個Hello Wold的例子與亞馬遜波利進行身份驗證。我只是想用我的憑據做一個簡單的http請求來獲得amazon web服務器並獲取音頻。那可能嗎？

我已經創建了IAM用戶，它看起來像這樣：

這是我迄今爲止，並沒有將文本轉換爲語音。我認爲問題是驗證。：/

static void Main(string[] args) 
    { 
     var accessKeyId = @"I place in here my access key"; 
     var secretKey = @"I place in here my secret key"; 

     //Amazon.Runtime.AWSCredentials credentials = new 
     AmazonPollyClient client = new AmazonPollyClient(accessKeyId, secretKey); 

     // Create describe voices request. 
     DescribeVoicesRequest describeVoicesRequest = new DescribeVoicesRequest(); 
     // Synchronously ask Amazon Polly to describe available TTS voices. 
     DescribeVoicesResponse describeVoicesResult = client.DescribeVoices(describeVoicesRequest); 
     List<Voice> voices = describeVoicesResult.Voices; 


     // Create speech synthesis request. 
     SynthesizeSpeechRequest synthesizeSpeechPresignRequest = new SynthesizeSpeechRequest(); 
     // Text 
     synthesizeSpeechPresignRequest.Text = "Hello world!"; 
     // Select voice for synthesis. 
     synthesizeSpeechPresignRequest.VoiceId = voices[0].Id; 
     // Set format to MP3. 
     synthesizeSpeechPresignRequest.OutputFormat = OutputFormat.Mp3; 
     // Get the presigned URL for synthesized speech audio stream. 
     var presignedSynthesizeSpeechUrl = client.SynthesizeSpeechAsync(synthesizeSpeechPresignRequest).GetAwaiter().GetResult(); 
     using (FileStream output = File.OpenWrite("hello_world.mp3")) 
     { 
      presignedSynthesizeSpeechUrl.AudioStream.CopyTo(output); 
     } 

     Console.Read(); 
    }

請注意這個例子編譯我不得不添加的NuGet包AWSSDK.Polly

'它沒有work'不是一個有效的問題陳述。更加詳細一些。 – tnw

IAM用戶是否有允許其使用Polly的權限策略？ –

是的，它可以完全訪問Polly。我剛剛註冊了亞馬遜網絡服務。難道是因爲我有一個免費賬戶？ –

你需要知道你叫憑據作爲第三個參數指定一個區域 - 即RegionEndpoint.USEast1。

即：

AmazonPollyClient client = new AmazonPollyClient("AKI5ZLVN6QXO123OJA", "4sYnPuAzMk/k07JA456728VbTpX4F5/FAKEGDiAKm", RegionEndpoint.USEast1);

（它無關，與它是一個免費帳戶）
