SpeechSynthesisResult这个类怎么引用？

在Java中引用SpeechSynthesisResult类，需先导入相关包，通常是com.alibaba.dashscope.audio.tts.SpeechSynthesisResult
该类代表一次流式语音合成的数据响应，包含音频片段(getAudioFrame())和对应的文本时间戳(getTimestamp()）。

音频数据和时间戳可能会在不同的数据帧中交替返回，因此在处理时需检查这两个方法的返回值是否为空。

使用时，通常配合SpeechSynthesizer类的streamCall()方法获取Flowable，并通过订阅或blockingForEach等操作处理每个返回的SpeechSynthesisResult实例。

代码示例：

package com.alibaba.dashscope.sample;

import com.alibaba.dashscope.audio.tts.SpeechSynthesisParam;
import com.alibaba.dashscope.audio.tts.SpeechSynthesisResult;
import com.alibaba.dashscope.audio.tts.SpeechSynthesizer;
import com.alibaba.dashscope.common.ResultCallback;
import com.alibaba.dashscope.common.Status;

import java.util.concurrent.CountDownLatch;

public class Main {
    public static void main(String[] args) {
        CountDownLatch latch = new CountDownLatch(1);
        SpeechSynthesizer synthesizer = new SpeechSynthesizer();
        SpeechSynthesisParam param = SpeechSynthesisParam.builder()
                .model("sambert-zhichu-v1")
                .text("今天天气怎么样")
                .sampleRate(48000)
                .enableWordTimestamp(true)
                .enablePhonemeTimestamp(true)
                      .apiKey("your-dashscope-api-key")
                .build();

    class ReactCallback extends ResultCallback<SpeechSynthesisResult> {

        @Override
        public void onEvent(SpeechSynthesisResult result) {
            if (result.getAudioFrame() != null) {
                // do something with the audio frame
                System.out.println("audio result length: " + result.getAudioFrame().array().length);
            }
            if (result.getTimestamp() != null) {
                // do something with the timestamp
                System.out.println("tiemstamp: " + result.getTimestamp());
            }
        }

        @Override
        public void onComplete() {
            // do something when the synthesis is done
              System.out.println("onComplete!");
            latch.countDown();
        }

        @Override
        public void onError(Exception e) {
            // do something when an error occurs
              System.out.println("onError:" + e);
            latch.countDown();
        }
    }

    synthesizer.call(param, new ReactCallback());
    try {
        latch.await();
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
    System.exit(0);
}

}
