如何将响应从Google Cloud Text-To-Speech流连接到NAudio库

问题描述

我想听声音，但我不想创建文件mp3。这是在具有.NET的桌面应用程序中。

我可以从Google Cloud中读取响应，然后创建文件mp3。我可以将该文件发送到NAudio库，然后进行播放。但是我需要跳过创建mp3文件的步骤。

你能帮我吗？谢谢。

    Dim credential_path As String = "C:\DESARROLLO\MyBrain\MyBrain2.json"
    System.Environment.SetEnvironmentvariable("GOOGLE_APPLICATION_CREDENTIALS",credential_path)

    Dim client As TextToSpeechClient = TextToSpeechClient.Create()
    Dim input As SynthesisInput = New SynthesisInput With {
        .Text = "Hello,World!"
    }
    Dim voice As VoiceSelectionParams = New VoiceSelectionParams With {
        .LanguageCode = "en-US",.SsmlGender = SsmlVoiceGender.Neutral
    }
    Dim config As AudioConfig = New AudioConfig With {
        .AudioEncoding = AudioEncoding.Mp3
    }

    ' Response from Google Cloud
    Dim response = client.SynthesizeSpeech(New SynthesizeSpeechRequest With {
        .Input = input,.Voice = voice,.AudioConfig = config
    })

    ' Create MP3
    Using output As Stream = File.Create("sample.mp3")
        response.AudioContent.Writeto(output)
        Console.WriteLine($"Audio content written to file 'sample.mp3'")
    End Using

    ' How connect the response from Google Cloud Text-To-Speech (Stream) to the NAudio Library
    Using ms As Stream = File.OpenRead("sample.mp3") ' response
        Using rdr = New Mp3FileReader(ms)

            Using wavStream = WaveFormatConversionStream.CreatePcmStream(rdr)

                Using baStream = New BlockAlignReductionStream(wavStream)

                    Using waveOut = New WaveOut(WaveCallbackInfo.FunctionCallback())
                        waveOut.Init(baStream)
                        waveOut.Play()

                        While waveOut.PlaybackState = PlaybackState.Playing
                            Thread.Sleep(100)
                        End While
                    End Using
                End Using
            End Using
        End Using
    End Using
