Watson 服务不支持哪些符号以避免 BadRequestException

what all are symbols not supported by Watson service to avoid BadRequestException

我目前正在使用 IBM Watson 的文本转语音 API，通过 Java SDK

代码如下

TextToSpeech textToSpeech = new TextToSpeech();
textToSpeech.setUsernameAndPassword(username, password);
ServiceCall<InputStream> inputStreamServiceCall = textToSpeech.synthesize(text, Voice.EN_ALLISON, AudioFormat.OGG);
InputStream in = inputStreamServiceCall.execute();

将文本转换为语音时出现以下异常

com.ibm.watson.developer_cloud.service.exception.BadRequestException: at com.ibm.watson.developer_cloud.service.WatsonService.processServiceCall(WatsonService.java:416) ~[java-sdk-3.3.0.jar:na] at com.ibm.watson.developer_cloud.service.WatsonService.execute(WatsonService.java:179) ~[java-sdk-3.3.0.jar:na]

我通过将以下符号“”©—’‘▒“{}|`\ 替换为 space 解决了这个问题。

请指出 watson 服务不支持的符号有哪些？

将您的 com.ibm.watson.developer_cloud java-sdk 升级到更高的 version.latest 是 3.8.0。在 java-sdk-3.3.0.jar 中，一些字符在 API 调用 watson 时没有正确编码。
