java - AWS Transcribe - 当我们看到 "IsPartial"标志设置为 False 时如何停止转录

Question

当 AWS Transcribe 仍在进行流式传输时，isPartial 标志将设置为 True。我想在 isPartial 标志设置为 False 后停止流传输，该怎么做？

有人做过吗？

https://docs.aws.amazon.com/transcribe/latest/dg/transcribe-dg.pdf#streaming

这是 Json:

      "Transcript": {

空音频帧表示流结束。正如文档中所指定的:“要结束音频数据流，请在事件流编码消息中发送空音频 block ”。
