ASR

(If enabled for the site)

The "ASR" Delivery method sends the audio of the current media for the node to an external service for Automatic speech recognition. The result will be parsed into Plint's internal subtitle format and attached to the current node. This means that a subsequent job in Plint Subtitler can automatically load this file for further work, such as post-editing. The file could also be automatically converted to a delivery format and used right away, although this is rarely recommended with raw ASR output.  

A typical setup:

  • A project with the correct source language specified
  • Attach/upload media to each part, in typical fashion
  • After the media steps (i.e. upload/convert/verify), add an ASR job
    • This job can be attached to the part itself, or to a target language
  • Follow this with a online editor job, for reviewing and adjusting the file

Once the media has been verified and this job is set to Done, the ASR job will trigger automatically.  When this process is completed, the ASR job will change status and the review/post-editing job will become open for work. A subtitle milestone will be stored and can be seen under Review / Track changes to enable easy comparison between the original and final versions. 

Settings

There are two main settings which can be applied to the ASR job:

  • Service
    • Depending on what is enabled for your platform, options may include "Azure", "AWS", and others. 
  • Segmentation
    • Rule-based segmentation will take into account the Report tool rules matching the job when splitting the text into individual subtitles, basing the subtitle length on the minimum/maximum duration setting. 
    • Whereas Sentence segmentation will allow longer clips and base the clip length on punctuation,  leaving the splitting for the post-editing stage. 
    • With both types, the Clip separation rule matching the project/job will always be applied to ensure that correct spacing is used between subtitles. 

Things to note

  • Depending on the segmentation type, somecertain values will be mandatory in the Report toolpreset willin be necessaryorder for the job to run properly. 
    • To ensure complete functionality with rule-based segmentation, make sure the Report preset has settings for:
      • Clip separation
      • Duration (min and max)
      • Maximum characters per line
    The ASR process can also be run "ad hoc" using the microphone icon in the joblist An ASR job set to "Awaiting corrections" will not run automatically
    • This status is used to indicate that something went wrong with the process and something will probably need to change before another attempt is made. 
    Ensure that the service you select supports the current source language, or the process will fail.
