Labeling Data

After a user selects a level, the system takes them to the labeling view for the assigned file. In the labeling view, users can listen to audio and either transcribe what they hear or edit an existing transcript.

Using the Audio Player

The labeling view provides an audio player with controls that allow users to play, pause, and jump to different times in the assigned audio file.

Using Keyboard Shortcuts

To help improve productivity, Hotpepper provides keyboard shortcuts that allow users to manipulate the audio player without using the player controls. For example, pressing TAB on the keyboard skips the audio player backwards by two seconds.

To see a list of available shortcuts, visit https://<YOUR_HOTPEPPER_URL>/instructions#shortcuts.

Managing Audio Settings

When using the audio player, users can control the following audio settings:

• Audio Speed: Increases or decreases the playback speed of the assigned file.
• Audio Gain: Increases or decreases the volume of the assigned file.

Transcribing Data

The majority of the labeling view consists of a textarea that contains the transcription of the assigned file where users can add and edit text.

Transcribing Automatically

For files assigned at level L1, users may be able to submit the assigned file to an on-premise Deepgram Speech Engine for automatic speech recognition (ASR) and transcription. When ASR is used, the Hotpepper server sends the assigned audio file to the configured Speech API endpoint, parses a transcript from the results, and automatically populates the Transcript textarea of the labeling view with the returned transcript.

To enable this feature, Hotpepper must be configured appropriately. When Hotpepper is properly configured for ASR, the File Details area of the labeling view will include a Get ASR button.

To learn more about configuring ASR for automatic transcription, visit Hotpepper User Guide: Setting Up.

Using Macros

To help improve productivity, Hotpepper provides built-in macros, which allow users to type string combinations that automatically expand. For example, typing “1” (the numeral 1 with a space after it) expands to “[SPEAKER 1:]”, and typing “ty” expands to “thank you”.

Managing File & Dataset Details

While transcribing or editing a file, various file details are available to the user:

• Last Saved: Time at which the current file was last saved.
• Filename: Name of the current file.
• Level: Level of labeling being performed on the current file.
• File History: History of the current file, which can include:
  • Action: Action that occurred. (Typically, this is update.)
  • User: User that performed the action.
  • Level: Review level of the file when the action was performed.
  • Status: Status of the file when the action was performed.
  • Time: Timestamp when the action was performed.

In addition, users may add notes about the file or dataset. For example, users may want to add details that may be commonly heard throughout a dataset, such as product names, people’s names, acronyms, or specialized terminology.

Handling Files

When labeling data, users can perform the following operations on the assigned file:

Saving

Users select Save to save the current transcript to the server and update Last Saved in the File Details. Hotpepper also periodically auto-saves transcripts.

Submitting

Users select Done to mark the assigned file as finished and send it to the next level for further labeling. Once the file is submitted, the system returns the user to the dashboard, so they can select another project.

Abandoning

Users select Abandon to opt out of working with a file. Once a user abandons a file, the file will no longer be available to the user at any level.

Pausing

By default, when a user exits the labeling view, work on the current file is paused. Users can also pause work on a file by clicking the Hotpepper icon or the browser’s back button.
