Analyze Past Calls (CallStudio)

VoiceHub’s CallStudio allows you to upload and analyze past calls — even if they weren’t made inside VoiceHub — using the same AI engine that powers real-time call analysis.

Upload a Job

  1. Go to CallStudio from the sidebar

  2. Click + Add Job

  3. Give the job a title

  4. Upload an audio file (MP3 or WAV, max size: 21MB)

  5. Click Save

Once uploaded, VoiceHub will transcribe the file and perform AI analysis just like with a live call.

Review the Analysis

After processing, each uploaded job generates detailed metrics:

  • Transcript

  • Total Call Duration

  • Agent Duration vs. Client Duration

  • Agent/Client Speaking Ratio

  • Interruptions Count

  • Record Summary (LLM-generated overview)

  • Main Topics Timeline

  • Detected Sentiment (Positive, Neutral, Negative)

  • Resolution Status (Manually editable or AI-evaluated)

  • Positive & Negative Keywords and Phrases

  • Downloadable Audio (for listening to the call in full)

You can play back the call while reviewing its metrics — great for human QA, training, or validation.

Use CallStudio for:

  • Post-call audits

  • Manual call QA

  • Human-in-the-loop scoring

  • Uploading logs from external contact centers

This feature complements real-time Call Logs by providing deeper insights into legacy audio — especially useful during migration or model fine-tuning.
