BPO 4.0: Why Contact Centers Are Thriving in the Age of Voice AI

AI is changing industries one by one. What has it done so far in contact centers?

UX, user experience: why is the digital world so obsessed with this term? Back in the days when we used dial-up to access the internet, no one thought of experience. But the progress and technologies made us, users, pretty picky. And because everything is created for one purpose, to satisfy customers and gain trust, UX has become a doctrine. But what does UX mean in the contact center domain, and do technologies really care about the agent’s experience or is the customer the main character?&nbsp;When you are in a line with an agent, you hardly imagine how they process data and how many interfaces they switch to get your issue resolved ASAP. On the other end of the line, we see agents who don't have time to think about tools. They're already thinking about the customer, the script, the call timer, and their KPIs. Adding another interface—another system to manage—isn’t a solution. It's a new source of stress. Yet this is how most voice AI technologies have approached "innovation": by layering dashboards, toggles, and analytics over conversations that are already cognitively demanding.&nbsp;<blockquote>What gets overlooked is that voice is not just another data stream. It's the medium through which agents process, respond, and build rapport in real time.&nbsp;</blockquote>&nbsp;The UX of voice AI can't be designed like visual software. It must be designed like sound: invisible, intuitive, and immediate.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Why Voice UX is Fundamentally Different</h2>Most UX design today is rooted in visual affordances. Users click, swipe, or tap to initiate and control an experience. In Voice AI and Hecttor AI, there's no such buffer. The user doesn’t click anything; they experience it. And that experience is driven by rhythm, clarity, and timing.&nbsp;With visual elements, a broken component will make the user frustrated but it may not have a significant impact on the experience. In voice AI, if the AI system misfires—whether through latency, poor audio rendering, or robotic speech—the disruption is not minor. It breaks the conversation, increases misunderstanding, and may even escalate tension. In a domain where 90% of customers rate "immediate response" as critical to satisfaction, these tiny breaks in timing have compounding effects.&nbsp;<blockquote>According to statistics, a&nbsp;<a style="text-decoration:none;" target="_blank" rel="noopener noreferrer" href="https://www.cisco.com/c/en/us/support/docs/voice/voice-quality/5125-delay-details.html#standarfordelaylimits">delay of just 250 milliseconds</a> in a customer interaction can degrade perceived empathy and attentiveness.</blockquote>&nbsp;This is why real-time Voice AI can't tolerate the norms of other AI products. It can't afford buffering, retries, or batch processing. The interface is the conversation itself.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">The Industry’s Missed Opportunity: Cognitive UX</h2>Most voice AI solutions treat speech as a technical challenge—a problem of recognition, transcription, or translation. They build massive language models, then layer agent tools over them: dashboards, confidence scores, and real-time guidance panels. These systems are powerful. But they're cognitively expensive.&nbsp;&nbsp;<blockquote>One of the latest reports found that&nbsp;<a style="text-decoration:none;" target="_blank" rel="noopener noreferrer" href="https://www.customercontactweekdigital.com/content-auto-download/651dcbe7a91fc259d071603a">67% of contact center agents</a> using AI tools feel overwhelmed by having "too many systems" open during live calls.</blockquote>&nbsp;The assumption is that more features equal more intelligence. But in reality, every added layer increases the cognitive load on the agent. In live calls, the brain can't switch contexts quickly. Asking an agent to read a dashboard while listening to emotional customer speech is a classic case of dual-task interference—a well-documented cognitive strain.&nbsp;<blockquote>As described in “Cognitive Control in Media Multitaskers”&nbsp;<a style="text-decoration:none;" target="_blank" rel="noopener noreferrer" href="https://www.pnas.org/doi/10.1073/pnas.0903620106">research</a>, multitasking in audio+visual contexts reduces task accuracy by half.</blockquote>&nbsp;This isn’t just inefficient. It's unsustainable. And it leads to burnout, turnover, and poor CX outcomes. Most tools interrupt more than they assist.&nbsp;They:<ul><li>Overload agents with alerts and dashboards</li><li>Create latency in communication due to cloud processing</li><li>Apply robotic-sounding transformations that reduce speaker authenticity</li><li>Or require agents to use new interfaces <img src="https://proper-serenity-0267541add.media.strapiapp.com/image_1_15c03c0b18.png" alt="image 1 .png" srcset="https://proper-serenity-0267541add.media.strapiapp.com/thumbnail_image_1_15c03c0b18.png 245w,https://proper-serenity-0267541add.media.strapiapp.com/small_image_1_15c03c0b18.png 500w,https://proper-serenity-0267541add.media.strapiapp.com/medium_image_1_15c03c0b18.png 750w,https://proper-serenity-0267541add.media.strapiapp.com/large_image_1_15c03c0b18.png 1000w," sizes="100vw" width="3584" height="1334"></li></ul><h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr"> Understanding Persona: Designing for the Agent</h2>Having played for both teams, as call center agents and product designers, we recognized the problem of cognitive load and the struggle agents face. When building Hecttor, we used our experience and we started not with the AI but with the agent. We found the way to pack our technology that would bring significant change in agent experience in their minute-by-minute reality of handling 80+ calls per day.&nbsp;Hecttor is not another control panel. It is a relief from misheard sentences and asking customers to repeat themselves to a clear, natural conversation and comprehension.So we designed Hecttor to be cognitively weightless. No button. No dashboards. Just a voice AI that adapts and works in the background to improve comprehension by adjusting the speech to agent comprehension and enhancing the audio itself, not by simplifying it, but by making it more neurologically processable.&nbsp;How?<ul><li>We slow down only the parts of speech that matter—terms with high information density.</li><li>We preserve speaker identity, rhythm, and emotion.</li><li>We achieve sub-200ms processing latency to maintain natural dialogue flow.</li><li>We do it all locally, without GPU or cloud dependency.</li></ul><h3 style="line-height:1.38;margin-bottom:4pt;margin-top:16pt;" dir="ltr">No More Layers</h3>We believe AI shouldn’t be a layer. It should be a channel. At Hecttor, the UX isn't about building a tool that agents use—it's about building a tool that helps them take full control of their productivity.&nbsp;That's why we designed Hecttor to disappear. If agents notice it, we’ve failed. Success means nothing stands in their way. Not latency. Not dashboards. Not robotic filters.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Rethinking Voice AI Design</h2>The challenge contact center agents are experiencing daily is not only the never-ending customer inquiries, but also interfaces that add to frustration. Businesses do business, true, but there should be something more behind the business: an excellent user experience without a learning curve, complicated navigation, and cognitive load. The industry needs to move away from designing for control and go towards designing for cognition. We don't need another "AI assistant" that interrupts or overexplains. We need systems that adapt to the rhythms of human thought and interaction.&nbsp;<blockquote>In a world of eye-first interfaces, Hecttor is built for the ear. Not to be heard louder. But to be understood better.</blockquote>&nbsp;<h3>&nbsp;</h3><h3>Because real-time voice UX isn't about what you build. It's about what you remove.</h3>&nbsp;

Voice AI UX for Contact Centers: Designing for Agents

When the user doesn’t see your product, every millisecond counts.

It is a cognitive bottleneck. For example, agents with English as a second language who are fluent still struggle with rapid speech, regional accents, and colloquialisms. All these become a challenge for serving customers efficiently and empathetically.&nbsp;&nbsp;The idea of Hecttor was born from multiple experiences of communication and comprehension barriers. It was built to address these challenges from the ground up—not as another performance tool, but as a live voice AI system that adjusts the pace and clarity of speech in real-time.&nbsp;&nbsp;We have talked much about the industry challenges, but let’s go behind the scenes and see what Hecttor is at its core.&nbsp;<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">The Problem: Speech Speed, Comprehension, and Cognitive Overload</h2>Speed isn’t just a matter of words per minute—it’s about processing dense streams of audio, often poor-quality audio, “decoding” unfamiliar phrasing, and making decisions under time pressure. Cognitive load theory suggests that the brain has a limited capacity for processing information, especially in working memory. When speech is too fast, agents burn out trying to understand what’s being said rather than focusing on what to say next.&nbsp;Unlike subtitles or playback tools for prerecorded videos or audio like YouTube’s 0.75x speed—which applies uniform slowdown—real conversations are dynamic and speed adjustment is not quite a common thing. You can never fully predict the speaker’s behavior.&nbsp;It introduces lag, which can disrupt real-time communication. That’s why pauses are uneven, emphasis varies, and speech patterns are unstable. Uniformly slowing down every syllable distorts natural prosody and makes the conversation feel robotic or disconnected. What’s needed is selective, context-aware, real-time pace adjustment.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">What Makes Real-Time Speech Adjustment Hard</h2>Slowing down audio sounds simple—until you realize you only have milliseconds to decide how to do it. Most systems manipulating speech (like podcast editors or language tools) work on pre-recorded files. That gives them full visibility into the pattern before making adjustments.&nbsp;&nbsp;But Hecttor,&nbsp;the world's first and only technology that works in real time, has an absolutely different approach. It works in real-time, which means it doesn’t know what’s coming next. Hecttor faced three major challenges:&nbsp;<ul><li>Latency: The system must process and return adjusted speech in under 200 milliseconds to keep conversations fluid. Otherwise, even the shortest delay repeated once may cause communication issues.</li></ul><blockquote>Business owners DO understand that even though customers don't feel the influence of technology, it directly impacts agent performance and subsequently helps resolve customer issues easier and faster.&nbsp;</blockquote><ul><li>Prosody Preservation: Slowing speech can't flatten tone, intonation, or emotional cues. These are critical to human communication. Unlike real-time voice translation or accent removal tools that may distort prosody, Hecttor needed to keep authenticity and adjust speech without applying an additional layer that changes the voice.</li><li>Device Constraints: Most contact centers don’t run high-performance machines. Many use older, overloaded desktops. Hecttor needs to perform complex computations without relying on a cloud GPU or high-end local hardware. This challenge is addressed by optimizing the performance to work stably on machines with limited performance.</li></ul><h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">The AI Behind Hecttor</h2>At the core of Hecttor is a hybrid system combining signal processing and machine learning. If we could use the word “magic” when talking about tech, we would definitely use it for Hecttor’s technology. Its predictive algorithms and real-time speech enhancement transform how spoken language is understood in fast-paced environments like contact centers. It detects speech patterns and intelligently adjusts the speed of incoming speech, just enough to improve comprehension without introducing noticeable delay. The system learns and adapts to user preferences and context, making the voice natural and easy to listen to, even over hundreds of calls a day.Besides speed adjustment, Hecttor uses speech enhancement techniques to improve voice clarity and reduce distractions. We go beyond traditional noise cancellation, helping agents focus on what matters: the speaker’s actual words.&nbsp;<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Real-Time, On-Device: Why It Matters</h2>While most AI tools run on the cloud, offering on-device integration of Hecttor was a strategic decision.&nbsp;<figure class="image"><img style="aspect-ratio:1792/680;" src="https://proper-serenity-0267541add.media.strapiapp.com/vizual_1_89e0e745e4.png" alt="vizual 1 .png" srcset="https://proper-serenity-0267541add.media.strapiapp.com/thumbnail_vizual_1_89e0e745e4.png 245w,https://proper-serenity-0267541add.media.strapiapp.com/small_vizual_1_89e0e745e4.png 500w,https://proper-serenity-0267541add.media.strapiapp.com/medium_vizual_1_89e0e745e4.png 750w,https://proper-serenity-0267541add.media.strapiapp.com/large_vizual_1_89e0e745e4.png 1000w," sizes="100vw" width="1792" height="680"></figure>&nbsp;<ul><li>Latency Minimization: Offloading to a server—even one with a high GPU—has more delays due to network roundtrips. For live conversations, this isn’t acceptable.</li><li>Security &amp; Compliance: Call centers are often legally prohibited from routing voice data outside their storage or servers. On-device processing ensures Hecttor aligns compliance and no data leaves the machine, solving privacy measures from the start.</li><li>Hardware Adaptability: Despite device constraints, we constantly optimize the model size and processing routines to run smoothly even on older machines common in contact centers.</li></ul>&nbsp;One of the major breakthroughs came with the voice boost feature that enhances clarity and speech only when needed. It detects weak audio input, amplifies relevant parts of speech, and avoids boosting background noise or silence. Combined with the noise cancellation feature, it dramatically improves low-quality call environments.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Hecttor at the Core: The Invisible Engine</h2>What makes Hecttor truly unique in its effectiveness isn’t just what it does—it’s how invisibly and seamlessly it does it.&nbsp;In real time, you won’t see any additional hardware or any manual adjustments while on the call. Hecttor listens, analyzes, and adjusts the speed of fast-paced speech—just enough for agents to understand everything without interrupting the natural flow of conversation. There’s no change in speech quality except for speed that feels like magic in a headset.&nbsp;Behind the scenes, Hecttor predicts where comprehension might break down and transforms the audio to match the agent’s listening capacity—all without ever recording or storing data.&nbsp;Once experienced, it’s hard to imagine running a contact center without it. That’s why early adopters are moving fast—and why speed adjustment is no longer a “nice-to-have” but a competitive necessity.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Integration with Enterprise Tech Stacks</h2>Hecttor’s innovation goes beyond its core functionalities. Successful enterprise adoption depends not just on product capability but also on deployment simplicity. We make sure Hecttor is lightweight—there’s no cloud dependency and no need for centralized management. Each agent gets Hecttor installed independently, whether in a 5-person team or a 5,000-seat operation.&nbsp;Hecttor is smoothly and automatically integrated with popular CCaaS platforms, softphones, and monitoring tools. That said, Hecttor supports large and small teams with equal productivity.&nbsp;<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Designed for Security, Privacy &amp; Compliance</h2>Every design decision behind Hecttor was made with security-first principles. Since all processing happens locally:&nbsp;<ul><li>No call data is sent externally.</li><li>No personal information is used or stored</li><li>Voice data never leaves the device or touches a cloud server.</li></ul>&nbsp;The system complies with SOC 2 Type 2 principles by default; integration provides complete transparency. The analytics service, where allowed, only tracks performance stats like CPU usage—never voice content.<h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">The Future of Hecttor</h2>Hecttor has just started its journey in voice AI and we have already managed to raise the issue of comprehension. Along with current features, Hecttor will soon be upgraded with new capabilities already in development, extending both the technical depth and the practical reach of Hecttor:<h3 style="line-height:1.38;margin-bottom:4pt;margin-top:16pt;" dir="ltr">Hecttor’s Bidirectional Speech Speed Adjustment</h3>One of the major upgrades will enable Hecttor’s speech speed adjustment and voice boost for both agents and customers. “Can you repeat that?” will remain in the past for agents AND customers, and communication will be all about understanding and problem-solving. As a result, contact centers will see better KPIs and more inclusive communication, particularly when agents and customers have different linguistic or cognitive processing speeds.&nbsp;<blockquote>By focusing on precision, adaptability, and mutual understanding, Hecttor’s evolution isn’t just technical—it’s human-centric at its core.</blockquote><h2 style="line-height:1.38;margin-bottom:6pt;margin-top:18pt;" dir="ltr">Conclusion</h2>This non-tech introduction to Hecttor’s technology is just a short overview of what is really happening at the core because Hecttor isn’t just a voice tech product—it’s a system built on deep respect for the complexity of human communication.&nbsp;&nbsp;When we were building Hecttor, we acknowledged that fluency isn’t binary and that understanding, especially under pressure, is a shared challenge across borders and professions. We've introduced real-time voice AI that works with people—not just for them.&nbsp;&nbsp;Today Hecttor is already expanding who really needs to succeed in customer service and, ultimately, who gets to be heard.<h3 style="line-height:1.38;margin-bottom:4pt;margin-top:16pt;" dir="ltr">Want to see Hecttor in action?
