Manual Call Scoring: Benefits and Drawbacks

Before diving into how AI-driven methods compare, let’s take a closer look at the ins and outs of manual call scoring.

How Manual Call Scoring Works

Manual call scoring relies on human evaluators who listen to call recordings and assess agent performance based on specific criteria. QA specialists select calls for review and follow established guidelines to evaluate them. Scoring typically focuses on factors like customer satisfaction, politeness, problem resolution, and adherence to scripts. These evaluations combine objective metrics, such as call duration and resolution rates, with subjective observations, like tone and rapport.

To ensure consistency, companies often hold calibration sessions - typically once a month or whenever QA standards are updated. These sessions help align evaluators’ interpretations and scoring methods. After scoring, evaluators provide feedback reports highlighting strengths and areas for improvement. While this structured approach has its merits, it also comes with notable challenges.

Benefits of Manual Call Scoring

Manual call scoring offers some clear advantages for quality assurance. Human judgment shines in complex situations where a nuanced understanding is crucial. Evaluators can interpret emotional tones and subtle customer sentiments that automated systems might overlook.

"While AI, especially with advancements in Generative AI and natural language processing, showcases promising strides in accurately evaluating agent performance, the human touch embodies an irreplaceable nuance and understanding of contextual subtleties." – Gennadiy Bezko

Another strength of manual scoring is its flexibility. Human evaluators can adapt to unique circumstances, tailoring their feedback to help agents improve. This approach is particularly valuable for evaluating complex or sensitive calls that demand a deep understanding of context. However, these benefits come at a cost - literally and operationally.

Drawbacks of Manual Call Scoring

Despite its strengths, manual call scoring faces several significant hurdles, particularly in terms of efficiency and scalability. The process is incredibly time-intensive, as evaluators must carefully review each recording. This limitation often means only a small fraction of customer interactions - typically 1–3% - gets reviewed.

Another issue is the potential for human error and bias. Different evaluators may apply varying standards, leading to inconsistent results. Studies show that human error rates for data entry alone range from 1% to 5%. As call volumes increase, scaling manual scoring becomes even more challenging. The labor-intensive nature of the process drives up costs and delays feedback, which can reduce the effectiveness of coaching efforts.

"Manual call scoring for quality assurance is better than no call scoring. Still, it is very time-consuming and prone to human error, making it necessary to explore automated solutions such as AI-driven voice analytics." – Gennadiy Bezko

AI Call Scoring: Features and Advantages

AI call scoring is changing the way quality assurance (QA) is handled, bringing automation and data-driven insights into the process.

How AI Call Scoring Works

AI call scoring relies on natural language processing (NLP) to examine calls, identify key phrases, and assess customer sentiment and emotions during interactions. It starts by converting speech into text and then uses machine learning algorithms to measure performance based on predefined criteria.

Unlike human evaluators who need to listen to entire conversations, AI can simultaneously analyze speech patterns, dialogue flow, compliance, and emotional tone to create detailed performance scores. These platforms integrate seamlessly with tools like CRM and contact center systems, pulling call data and presenting insights on familiar dashboards.

The scoring process can happen in real-time or near real-time, enabling managers to address issues or seize opportunities as they emerge. Sentiment analysis highlights moments where customers may feel frustrated or when agents appear disengaged. This automated approach eliminates many of the inefficiencies associated with manual scoring.
