Question

我正在尝试通过麦克风进行直接实时录制并将其显示为文本，但是找不到一个很好的例子

我有一种方法如何显示字节数组中的文本，但是找不到使用Google Speech API将麦克风语音直接流式传输为文本的好方法我的Google Speech API转换功能：

public static void streamingRecognizeFile(byte[] audioData) throws Exception {
        try (SpeechClient speech = SpeechClient.create()) {

            // Configure request with local raw PCM audio
            RecognitionConfig recConfig =
                    RecognitionConfig.newBuilder()
                            .setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
                            .setLanguageCode("de-DE")
                            .setSampleRateHertz(16000)
                            .build();
            StreamingRecognitionConfig config =
                    StreamingRecognitionConfig.newBuilder().setConfig(recConfig).build();

            class ResponseApiStreamingObserver<T> implements ApiStreamObserver<T> {
                private final SettableFuture<List<T>> future = SettableFuture.create();
                private final List<T> messages = new java.util.ArrayList<T>();

                @Override
                public void onNext(T message) {
                    messages.add(message);
                }

                @Override
                public void onError(Throwable t) {
                    future.setException(t);
                }

                @Override
                public void onCompleted() {
                    future.set(messages);
                }

                // Returns the SettableFuture object to get received messages / exceptions.
                public SettableFuture<List<T>> future() {
                    return future;
                }
            }

            ResponseApiStreamingObserver<StreamingRecognizeResponse> responseObserver = new ResponseApiStreamingObserver<>();

            BidiStreamingCallable<StreamingRecognizeRequest, StreamingRecognizeResponse> callable = speech.streamingRecognizeCallable();

            ApiStreamObserver<StreamingRecognizeRequest> requestObserver = callable.bidiStreamingCall(responseObserver);

            // The first request must **only** contain the audio configuration:
            requestObserver.onNext(StreamingRecognizeRequest.newBuilder().setStreamingConfig(config).build());

            // Subsequent requests must **only** contain the audio data.
            requestObserver.onNext(StreamingRecognizeRequest.newBuilder()
                    .setAudioContent(ByteString.copyFrom(audioData))
                    .build());

            // Mark transmission as completed after sending the data.
            requestObserver.onCompleted();

            List<StreamingRecognizeResponse> responses = responseObserver.future().get();

            for (StreamingRecognizeResponse response : responses) {
                StreamingRecognitionResult result = response.getResultsList().get(0);
                SpeechRecognitionAlternative alternative = result.getAlternativesList().get(0);
                System.out.printf("Transcript : %s\n", alternative.getTranscript());
            }
        }
    }

有人知道我应该在哪里添加什么内容并直接从麦克风听吗？我可能需要一个好的解决方案来直接从麦克风读取字节数组，但是我不确定。

Google Speech API使用Java从麦克风流到文本
