Really Feel on Every Call

What Call Sentiment Analysis Actually Detects

Sentiment analysis on customer calls goes far beyond "positive" and "negative". A well-trained model identifies distinct emotional states throughout the conversation, mapped to specific moments in the transcript. Here is what it surfaces:

Why Sentiment Analysis Beats CSAT Surveys

Factor	CSAT Surveys	Call Sentiment Analysis
Response rate	5 to 15% typical	100% coverage
When data is available	Hours or days later	Immediately after upload
Granularity	Single overall score	Per-segment emotion tracking
Actionability	Tells you what, not why	Points to the exact moment things went wrong
Bias	Response bias (unhappy customers over-respond)	Based on actual conversation signals
Cost	Survey platform + incentives	Free with Bolo Aur Likho

How Sentiment Analysis Works on Hindi and Hinglish Calls

Sentiment analysis on Indian sales calls is more complex than English-only tools can handle. Indian agents and customers frequently switch between Hindi, English, and regional languages mid-sentence. Emotional expression in Hindi uses different idioms, intensity markers, and indirect communication styles that a purely English-trained model misses.

Bolo Aur Likho's sentiment analysis is built on top of OpenAI Whisper and processes transcripts in their native language, preserving Hinglish expressions and their emotional context rather than forcing translation first.

Practical Uses for Sales Managers

• Churn prediction: Customers who sound frustrated on retention calls are far more likely to churn. Flagging these calls for immediate supervisor callback can save the relationship.
• Conversion coaching: Agents whose calls show high confusion in the middle of the pitch need product knowledge training, not a different closing technique.
• Compliance risk identification: Calls where customer sentiment shifts negative after a pricing or disclosure discussion may indicate mis-selling language was used.
• Recognition: Identifying calls with consistently positive customer sentiment helps you understand what your top performers are doing differently.
