Analyzing call center audio with Call Analytics

Use Amazon Transcribe Call Analytics to gain insight into customer-agent interactions. Call Analytics provides you with:

Call Analytics can also help increase staff productivity by reducing the need for manual note-taking after each call. It also reduces the time required by supervisors to read transcripts or listen to audio recordings.

Call Analytics use cases

  • Monitor issue frequency over time: Use call categorization to identify recurring keywords within your transcripts.

  • Gain insight into your customer service experience: Use call characteristics (non-talk time, talk time, interruptions, voice loudness, talk speed) and sentiment analysis to determine if customers' issues are being appropriately resolved during their call.

  • Ensure regulatory compliance or adherence to company policy: Set keywords and phrases for company-specific greetings or disclaimers to verify your agents are meeting regulatory requirements.

  • Improve handling of customer data: Use transcript and audio redaction to protect customer privacy.

  • Improve staff training: Use criteria (sentiment, non-talk time, interruptions, talk speed) to flag transcripts that can be used as examples of positive or negative customer interactions.

  • Measure staff efficacy in creating a positive customer experience: Use sentiment analysis to measure if your agents are able to turn a negative customer sentiment into a positive one as calls progress.

  • Improve data organization: Label and sort calls based on custom categories (including keywords and phrases, sentiment, talk time, and interruptions).

  • Quickly summarize the important aspects of a call without needing to review the entire transcript: Use automatic call summarization to get a succinct summary of all issues, action items, and outcomes identified in a given call.
