Built-in Metadata Filters

Add built-in metadata filters to define which files should be included for analysis. V‑Spark includes the following built-in metadata for each file:

  • Gender: filters results based on Agent or Client gender: All, Male, Female.

  • Emotion: filters results based on Agent, Client, or Overall emotion: Positive, Negative, Improving, or Worsening. Positive calls remain positive or neutral throughout the call. Negative calls remain neutral or negative throughout the call. Improving calls begin negative and progress to positive by the end of the call. Worsening calls begin positive but decline to negative by the end of the call.

  • Call Duration: filters results to include only calls within a call duration range.

  • Call Silence Time: filters results based on the percentage of non-speech duration. Calls with 100% silence contain maximum silence. A percentage range may be defined using a slider.

  • Voice Clarity: filters results based on how clear the Agent or Client sounds on the recording. Speakers with 100% clarity would be the clearest. Low clarity indicates speech that is hard to understand , possibly due to poor phone signal, background noise, or speaker accent or enunciation. A percentage range my be defined using a slider.

  • Overtalk: filters results based on the percentage of turns that an Agent talks over the Client. Overtalk of 100% indicates that the Agent spoke over the Client throughout the entire call. A percentage range may be defined using a slider.

  • Diarization: filters results based on how well mono (single-channel) audio was separated into multiple speakers for analysis using a process called "diarization." Diarization of 100% indicates the highest quality speaker separation.

Important

Only one filter may be added for each metadata type. Agent and Client filters are considered to be different metadata types.
