在阿里语音AI中，现在是这样写的怎么改？

private static FlowingSpeechSynthesizerListener getSynthesizerListener() {
FlowingSpeechSynthesizerListener listener = null;
try {
listener = new FlowingSpeechSynthesizerListener() {
File f=new File("flowingTts.wav");
FileOutputStream fout = new FileOutputStream(f);
private boolean firstRecvBinary = true;

        //流入语音合成开始
        @Override
        public void onSynthesisStart(FlowingSpeechSynthesizerResponse response) {
            System.out.println("name: " + response.getName() +
                    ", status: " + response.getStatus());
        }
        //服务端检测到了一句话的开始
        @Override
        public void onSentenceBegin(FlowingSpeechSynthesizerResponse response) {
            System.out.println("name: " + response.getName() +
                    ", status: " + response.getStatus());
            System.out.println("Sentence Begin");
        }
        //服务端检测到了一句话的结束，获得这句话的起止位置和所有时间戳
        @Override
        public void onSentenceEnd(FlowingSpeechSynthesizerResponse response) {
            System.out.println("name: " + response.getName() +
                    ", status: " + response.getStatus() + ", subtitles: " + response.getObject("subtitles"));

        }
        //流入语音合成结束
        @Override
        public void onSynthesisComplete(FlowingSpeechSynthesizerResponse response) {
            // 调用onSynthesisComplete时，表示所有TTS数据已经接收完成，所有文本都已经合成音频并返回。
            System.out.println("name: " + response.getName() + ", status: " + response.getStatus()+", output file :"+f.getAbsolutePath());
        }
        //收到语音合成的语音二进制数据
        @Override
        public void onAudioData(ByteBuffer message) {
            try {
                if(firstRecvBinary) {
                    // 此处计算首包语音流的延迟，收到第一包语音流时，即可以进行语音播放，以提升响应速度（特别是实时交互场景下）。
                    firstRecvBinary = false;
                    long now = System.currentTimeMillis();
                    System.out.println("tts first latency : " + (now - FlowingSpeechSynthesizerDemo.startTime) + " ms");
                }
                byte[] bytesArray = new byte[message.remaining()];
                message.get(bytesArray, 0, bytesArray.length);
                System.out.println("write array:" + bytesArray.length);
                fout.write(bytesArray);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        //收到语音合成的增量音频时间戳
        @Override
        public void onSentenceSynthesis(FlowingSpeechSynthesizerResponse response) {
            System.out.println("name: " + response.getName() +

        }
        @Override
        public void onFail(FlowingSpeechSynthesizerResponse response){
            // task_id是调用方和服务端通信的唯一标识，当遇到问题时，需要提供此task_id以便排查。
            System.out.println(
                    "session_id: " + getFlowingSpeechSynthesizer().getCurrentSessionId() +
                            ", task_id: " + response.getTaskId() +
                            //状态码
                            ", status: " + response.getStatus() +
                            //错误信息
                            ", status_text: " + response.getStatusText());
        }
    };
} catch (Exception e) {
    e.printStackTrace();
}
return listener;

}可以参考下这个。此回答整理自钉群"阿里语音AI【6群】"
