我正在尝试使用 aws Transcribe 将 wav 文件转换为文本。我已将 wav 文件上传到 S3，它位于此处，具有公共读/写权限：https ://s3.us-east-1.amazonaws.com/csld8xmsdksdf8s9sk3mmdjsdifkjksdijsldk/Transcribe2.wav 。wav 文件有效。我可以在我的浏览器中下载并重播它（听起来像是原始录音），所以我认为我们可以排除无效的输入文件、文件权限等。
我正在使用 java 版本：1.8.0_275 for mac。
我希望我的程序将转录文本返回给我：“你好，亚马逊订阅，这是什么？”
这是实际的程序输出，包括异常：
