在 java 中为 Android 使用 Microsoft Speech API 文字转语音？

Question

我正在尝试在 Android 的 java 项目中使用 Microsoft Speech API 文本转语音。它不工作。是否可以在 java 中使用此 API？

语音转文本功能正常，我发现 the Quickstart 并且使用起来没有问题。

然而，没有java文本转语音的例子，只有C#, C++ (Windows) and C++ (Linux)。

我尝试修改 java 中的代码，但它不起作用，我也不知道为什么。

 public void onTextToSpeechButtonClicked(View v) {
        TextView txt = (TextView) this.findViewById(R.id.texttospeech); // 'texttospeech' is the ID of my text view

        try {
            // THIS LINE ISN'T WORKING
            com.microsoft.cognitiveservices.speech.internal.SpeechConfig config = com.microsoft.cognitiveservices.speech.internal.SpeechConfig.FromSubscription(speechSubscriptionKey, serviceRegion); 

            config.SetSpeechRecognitionLanguage("fr-FR");
            assert(config != null);

            // Creates a speech synthesizer using the default speaker as audio output
            SpeechSynthesizer synthesizer = SpeechSynthesizer.FromConfig(config);
            assert(synthesizer != null);

            SpeechSynthesizer synthesizer1 = SpeechSynthesizer.FromConfig(config);


            SpeechSynthesisResult result = synthesizer.SpeakTextAsync(txt.toString()).Get();

            // Checks result
            if (result.getReason().equals(ResultReason.SynthesizingAudioCompleted)){
                txt.setText("The text has been said.");
            }
            else if (result.getReason().equals(ResultReason.Canceled)){
                SpeechSynthesisCancellationDetails cancellation = SpeechSynthesisCancellationDetails.FromResult(result);
                txt.setText("CANCELED: Reason ="+cancellation.getReason());
                if(cancellation.getReason().equals(CancellationReason.Error)){
                    txt.append("ErrorCode = "+cancellation.getErrorCode()+" / ErrorDetails = "+cancellation.getErrorDetails()+" / Did you update the subscription info ?");
                }
            }
            synthesizer.delete();

        } catch (Exception ex) {
            Log.e("SpeechSDKDemo", "unexpected " + ex.getMessage());
            assert(false);
        }
    }

我在日志中的内容是：

E/ples.quickstar: No implementation found for void com.microsoft.cognitiveservices.speech.internal.carbon_javaJNI.swig_module_init() (tried Java_com_microsoft_cognitiveservices_speech_internal_carbon_1javaJNI_swig_1module_1init and Java_com_microsoft_cognitiveservices_speech_internal_carbon_1javaJNI_swig_1module_1init__)

有人可以帮助我吗？

Answer 1

我搜索了 Microsoft Speech API 是否与 Java 兼容，答案是否定的。这似乎也有点明显，因为 Microsoft = C++ / C# 这与 Java 完全不同。此外，在您的 post 中，您提到了 the Quickstart。这使用认知服务语音 SDK 而不是 Microsoft SAPI.

但是，有原生 Java 库允许文本转语音。这是关于它的 post related to Text-To-Speech engines. Here is more information。还有一些库可用于 Android:

我会建议一个替代方案。为什么不尝试使用 windows tts，而是将文本发送到可以从 java 代码执行的 powershell 命令：

 String[] command = {"powershell.exe", "Add-Type -AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).Speak('" + message +"');"};
 try {
        ProcessBuilder pb = new ProcessBuilder(command);
        Process process = pb.start();
        System.out.format("Process exit code: %d", process.waitFor());
        ProcessInputOutput.readStdnOutput(process);
    }
    catch (Exception e){
        e.printStackTrace();
    }
