在系统环境变量中设置GOOGLE_APPLICATION_CREDENTIALS后，我尝试使用Google云语音API。无法找出任何问题或解决超过2天。
这是我得到的错误

我试过的JAVA实现
public String convertToText(MultipartFile file) throws Exception {
SpeechClient speech = SpeechClient.create();
byte[] data = file.getBytes();
ByteString audioBytes = ByteString.copyFrom(data);
System.out.println("1**********");
// Builds the sync recognize request
RecognitionConfig config = RecognitionConfig.newBuilder()
.setEncoding(AudioEncoding.LINEAR16)
.setSampleRateHertz(16000)
.setLanguageCode("en-US")
.build();
RecognitionAudio audio = RecognitionAudio.newBuilder()
.setContent(audioBytes)
.build();
// Performs speech recognition on the audio file
RecognizeResponse response = speech.recognize(config, audio);
List<SpeechRecognitionResult> results = response.getResultsList();
String recText = "";
for (SpeechRecognitionResult result: results) {
List<SpeechRecognitionAlternative> alternatives = result.getAlternativesList();
for (SpeechRecognitionAlternative alternative: alternatives) {
System.out.printf("Transcription: %s%n", alternative.getTranscript());
recText+= " "+alternative.getTranscript();
}
}
speech.close();
return recText;
}
我正在使用Tomcat（我不想使用Jetty）来部署我的.war文件。
互联网上有很多问题似乎没有人回答这个问题！任何帮助将不胜感激！
答案 0 :(得分：1)
Tomcat使用的Netty-tcnative 1.x是incompatible with tcnative。使用netty-tcantive 2.x解决不兼容问题。使用新的netty-tcnative required updates到grpc-java，它将包含在下一个版本1.4.0中，计划于6月6日发布。
