Sentiment analysis is a valuable business intelligence feature that helps companies gain deeper insights into customer interactions. It enables teams to identify opportunities for improvement, enhance customer experience, and make data-driven decisions.

Some key benefits include:

  • Helping managers detect bottlenecks and areas of improvement in Customer Support.
  • Allowing agents to assess the tone of their last customer call and adapt accordingly.
  • Enabling teams to quickly filter and prioritize calls with negative sentiment.
  • Supporting large-scale analysis across all calls.
  • Reducing personal bias when evaluating customer interactions.

Who has access

Sentiment analysis is available to users subscribed to the AI Assist add-on.

The feature applies to:

  • Calls made by users with an assigned AI License.
  • Calls longer than 1 minute.
  • Calls with transcripts available in English (EN), French (FR), Spanish (ES), German (DE), Dutch (NL), Italian (IT), or Portuguese (PT). 

You can view sentiment analysis results in both the Conversation Center and on each recording/voicemail page.

Note: Sentiment analysis will only be available for calls made after the feature is enabled. It will not retroactively analyze past calls.

Functionality

What is sentiment analysis?

Sentiment analysis detects a customer’s mood after a conversation. Aircall’s sentiment analysis uses language models to evaluate call transcripts and classify them according to emotion and sentiment patterns.

Important: Since Aircall’s sentiment analysis relies solely on call transcripts, it does not take into account any audio elements such as tone of voice.

How users can interact with sentiment analysis

Users can:

  • View the overall customer mood for each conversation.

Legal and compliance

Depending on your industry and location, using sentiment analysis may trigger compliance requirements.

If you wish to disable the AI Sentiment Analysis feature, please reach out to our Customer Support team. Disabling the feature will remove sentiment analysis for your entire account.

Limitations

While sentiment analysis provides valuable insights, it has a few limitations:

  • It evaluates only text-based transcripts, not the tone or emotion present in audio.
  • It reflects only the customer’s mood, not whether the call was positive or negative for your business. For example, a customer expressing frustration toward a competitor may still be marked as having negative sentiment.
  • It does not account for the call’s outcome or business impact.
Tip: Use sentiment analysis alongside other Aircall insights, such as call outcomes and notes, for a complete view of customer interactions.
