While agents were highly skilled, some customers struggled to understand them, leading to communication hurdles impacting efficiency and customer satisfaction. To address this, arrivia implemented Krisp’s AI Accent Conversion (AC), enhancing speech clarity while preserving the natural tone and flow of the conversation.
This initiative followed earlier success with Krisp Noise Cancellation (NC), which dramatically improved customer interactions and agent focus. With both noise and accent clarity optimized, arrivia a transformed its call experience, achieving:
● 99% increase in NPS
● +26.1% boost in sales conversion
● +14.8% increase in revenue per booking
● 4.4% reduction in call handle time and more.
Arrivia’s call centers, particularly in India and the Philippines, were vibrant and full of energy, but that also meant background noise and voices often disrupted calls. The challenge was even greater for their large outbound operations, where customer expectations were higher, and clear call audio was essential for successful interactions. Customers struggled to hear agents clearly, leading to miscommunications andfrustration, negatively impacting Net Promoter Scores (NPS).
Arrivia initially tried solving the issue with noise-canceling headphones. However, these only reduced noise for one side of the conversation, required frequent replacements, and incurred ongoing costs. Realizing they needed a scalable and effective solution, arri vi a turned to Krisp’s AI-powered Noise Cancellation. The technology filtered out unwanted background noise bidirectionally in real time, ensuring clear, uninterrupted communication between agents and customers.
With NC in place, arrivia experienced significant improvements:
● 44% reduction in negative NPS impact from background noise.
● Greater customer confidence and engagement.
● Agents, enabled to focus better, leading to improved performance.
With background noise eliminated arrivia’s leadership identified a new area for improvement—accent clarity.
Despite agents’ strong language skills, some customers found their accents difficult to understand, especially in North America. This led to misunderstandings, longer call times, and lower customer satisfaction. Additionally, some business lines and partners required a native U.S. accent, limiting operational flexibility.
Arrivia needed a way to maintain its diverse talent pool while ensuring clear, effective, and unbiased communication with customers.
Having already seen success with Krisp’s Noise Cancellation, arrivia turned to Krisp’s AI Accent Conversion to enhance customer-agent communication. Arrivia’s had already been using Krisp successfully, and Accent Conversion seamlessly integrated into their existing workflow without requiring complex IT changes.
Krisp’s flexibility with the proof-of-concept testing and rapid implementation made it an easy decision. No other solution offered the same level of customization, ease of use, and immediate impact on customer satisfaction and operational efficiency.
Krisp Accent Conversion comes in two modes:
● Voice Preservation – Maintains the agent’s natural voice while reducing harder-to-understand aspects of their accents for improved clarity.
● Voice Profiles – Offers diverse natural-sounding male and female preset voice profiles with complete accent conversion.
To evaluate the impact of AI Accent Conversion, arrivia a launched a 120-day pilot with 20 agents in India. The test was conducted with agents from the Cruise Sales team, as this line of business required a high level of customer trust and clear communication for successful conversions. Implementing a data-driven approach, arrivia first evaluated the group’s performance for 30 days without Krisp Accent Conversion, followed by a 90-day usage of the Voice Profiles mode of the product.
● Agents used Accent Conversion on every call to ensure consistent results.
● Performance was measured using a weighted scorecard methodology for 6 core KPIs
● Results were compared against the same group’s pre-AC performance to track improvements.
The results speak for themselves. Within only 90 days, arrivia saw:
● Net Promoter Score increased by ~99%, driven by a +10.4% improvement in the likelihood to recommend.
● Sales conversion rate increased by +26.1%, confirming clearer communication led to better outcomes.
● Revenue per booking improved by +14.8%, contributing to tangible business growth.
● Agent Promoter Score improved by +12.2%, signaling greater confidence among agents.
● Margin per Hour increased by +11.7%, enhancing operational efficiency.
● Call handle time improved by 4.4%, leading to faster, more effective interactions.
One of the most striking aspects of this implementation was that the core professionalism and approach to customer service remained unchanged. The only change was the accent, which had an immediate impact on removing bias and driving improvements across all key business metrics.
AI Accent Conversion also influenced arrivia’s strategic planning. While the India location had consistently been high-performing and cost-effective, certain lines of businesses and partners previously required a native U.S. accent, limiting the ability to service them from this region. By removing accent-related barriers, arrivia can now expand opportunities for these teams, increasing flexibility in workforce deployment.
Following the success of the Accent Conversion pilot, arrivia expanded its rollout:
● 100 additional agents across multiple lines of business are now using AI Accent Conversion.
● New POC: Testing Voice Preservation Mode for outbound teams handling high-sensitivity calls.
● New POC: arrivia is also piloting Krisp’s Filipino English accent pack to enhance interactions in its Philippines operations.
