IBM Watson语音到文本仅返回Java SDK中的第一个单词

我正在使用IBMWatson语音到文本JavaSDK，当我上传.wav文件时，响应JSON只包含第一个转录的单词。当我将相同的文件上传到web演示时，我得到了完整的响应

使用SDK实现非常简单：

SpeechToText service = new SpeechToText();
service.setUsernameAndPassword("<username>", "<password>");

File audio = new File("src/test/resources/sample1.wav");

SpeechResults transcript = service.recognize(audio, HttpMediaType.AUDIO_WAV);
System.out.println(transcript);

SpeechToText服务=新建SpeechToText（）；
service.setUserName和密码（“，”）；
文件音频=新文件（“src/test/resources/sample1.wav”）；
SpeechResults转录本=service.recognize（音频，HttpMediaType.audio_WAV）；
系统输出打印文本（抄本）；

您正在使用的

识别（）

签名将在第一次暂停后返回。要查看所有结果，请执行以下操作：

RecognizeOptions options = new RecognizeOptions();
options = options.continuous(true)
          .contentType(HttpMediaType.AUDIO_WAV)
          .interimResults(false)
          .inactivityTimeout(10)
          .maxAlternatives(1)
          .wordConfidence(false)
          .timestamps(true)
          .model("en-US_BroadbandModel");
SpeechResults transcript = service.recognize(audio, options);

这对我来说适用于使用以下maven依赖项：

<dependency>
  <groupId>com.ibm.watson.developer_cloud</groupId>
  <artifactId>java-sdk</artifactId>
  <version>2.8.0</version>
</dependency>

com.ibm.watson.developer\u云
java sdk
2.8.0

我正在尝试完全相同的事情，使用Chris K描述的相同参数（除了“中间结果=真”）

但是，它仍然抛出一个异常

这似乎与这个问题有关

---

这将在里程碑2.9.0中实现（当前为2.8.0）

它对我有效，中期结果为真。您不应该在

speechResults.isFinal（）

上执行

lock.countDown（）

操作-有多条消息是最终消息（每次演讲暂停时都会发生）。很好，没有在任何地方看到记录。回答中没有解释这一点，但是将

continuous

选项设置为

true

是检索所有结果的关键，而不仅仅是第一次暂停后的结果。
