Transcribe from another language

[weiping-bj]

Hi,

I plan to test this demo using a Chinese language video.

To make Transcribe support Chinese, I exported lambda function code "transcribe-MediaAnalysisStac-*.zip" and modified two files: /lib/transcribe/transcribe.js and /lib/transcribe/transcribe.js (I only changed LanguageCode from "en-US" to "zh-CN")

I used aws lambda update-function-code command to update this lambda function and got a success respond.

But I encountered an error respond when I tried to create metadata. Error messages are as follows:

{
  "Error": "AnalyticsError",
  "Cause": "{\"errorMessage\":\"media-analytics-solution state machine failed, FAILED\",\"errorType\":\"AnalyticsError\",\"stackTrace\":[\"exports.getAnalyticsStateMachine (/var/task/lib/metadata/analytics/index.js:206:13)\",\"<anonymous>\",\"process._tickDomainCallback (internal/process/next_tick.js:228:7)\"]}"
}

Does anyone could guide me how to fix this issue?

Thanks

Hi @weiping-bj,

The problem you encountered is because Chinese language is currently not supported with Amazon Comprehend (our NLP service). Although Amazon Transcribe can process zh-CN, the analysis state machine will still fail when it runs the NLP process with Amazon Comprehend.

Hi @aws-kens ,

Thanks for your feedback. I have two more questions.

1. Based on my understanding, if the analysis state machine would throw an error when it runs Comprehend, Transcribe process should be successfully executed. But I didn't find any executed jobs in Transcribe console (either successful or failed). Please correct me if my understanding is wrong.
2. How to bypass Comprehend if I just need transcribe and subtitle function?

Thanks

Hi @weiping-bj,

1) You are right. If it runs the Transcribe service, you should be able to see the job in Transcribe. There is a state machine called media-analysis. You can check to see if the detail error from that state machine. 2) With the current version, you would need to modify the media analysis state machine to bypass the Comprehend logic. We do have a beta private program for Media2Cloud V2 that can disable specific AIML detections. Let me know if you are interested, I will send you a separate email.

Hi @weiping-bj, We have just launched a major update of Media2Cloud V2 that has a lot of enhancements and new features. V2 should resolve the problem you had before. Give it a try
