How Event Planners Are Using AI Voice to Automate Guest Communications
Executive Summary
In 2025, the landscape of event planning is undergoing a radical transformation, moving beyond traditional, labor-intensive methods toward an era of intelligent automation. The leaders in the events industry—from those orchestrating high-stakes corporate conferences and bespoke luxury weddings to those managing multi-day trade shows with thousands of attendees—are no longer burdened by endless phone lists, manual RSVP confirmations, or the relentless task of chasing down last-minute guest updates. Instead, they are turning to advanced AI voice technology to manage guest communications with unprecedented speed, personalization, and precision.
Synthesys AI voice agents have emerged as the always-on, intelligent concierge for event planners. These sophisticated agents can engage in natural, human-like conversations to perform a wide range of tasks: confirming attendance, managing dietary restrictions and accessibility requests, providing detailed venue directions, pushing out real-time schedule updates, and responding to a multitude of last-minute inquiries. They do this in a seamless, brand-consistent voice, and can switch between languages effortlessly to serve a diverse global audience. Unlike a traditional human-only team, which is limited by bandwidth and time zones, a Synthesys AI voice system can handle thousands of guest interactions simultaneously, ensuring that every message is received and every guest feels valued.
This is not merely a marginal upgrade in operational efficiency; it is a fundamental redefinition of the entire guest communication lifecycle. Event planners who are leveraging Synthesys are not just reclaiming hundreds of hours of administrative time; they are delivering a consistently superior, proactive guest experience that significantly enhances brand reputation, drives repeat business, and provides the kind of operational scalability that allows their business to grow without the linear addition of staff.
Market Size & Growth
The global events industry, valued at approximately $1.2 trillion in 2024, is on a trajectory of significant expansion, with projections indicating a rise to $2 trillion by 2032, representing a robust Compound Annual Growth Rate (CAGR) of over 6.8% (Allied Market Research, 2024). This growth is not just a result of a return to in-person gatherings; it is being propelled by the rise of hybrid event formats and increasingly high guest expectations for instant, personalized, and real-time updates.
Within this massive market, the adoption of event technology—including automation, AI, and virtual event tools—is accelerating at a staggering 17% CAGR. This trend is driven by several critical factors related to guest communication:
Proactive Personalization: An overwhelming 68% of attendees now expect proactive, personalized event updates delivered to them through their preferred channels. This moves the industry beyond generic email blasts to tailored, on-demand information.
Addressing Communication Failures: A significant 45% of event-related complaints are directly linked to unclear or delayed communications. This highlights a key area of operational friction that AI is uniquely positioned to solve.
Market Opportunity: The market for AI-powered guest engagement platforms is forecast to capture an estimated $12 billion of the events tech market by 2030, demonstrating a clear and growing demand for solutions like Synthesys.

Narrative takeaway: As event scales and guest expectations for personalized communication rise, the ability to automate a significant portion of the conversation becomes the single biggest lever for both efficiency and guest satisfaction.
Key Adoption Drivers
The decision for event planners to adopt AI voice technology is rooted in a fundamental need to overcome the limitations of manual processes and create a superior guest experience. The key drivers behind this shift include:
Real-Time, Scalable Communication: Events, whether a 50-person conference or a 10,000-attendee festival, are defined by a high volume of time-sensitive inquiries and updates. A human team can only answer one call at a time. Synthesys AI voice handles guest outreach instantly, scaling to meet peak demand from thousands of guests simultaneously without creating human bottlenecks or call queues. When a keynote speaker has to change rooms, the AI can call every attendee of that session in minutes.
Multilingual Guest Experience: In a globalized world, event audiences are often diverse. Providing a welcoming and inclusive experience requires communication in multiple languages. Synthesys can switch seamlessly between languages and regional accents, ensuring clarity and inclusivity without the need for a multilingual staff on payroll. A planner in New York can use the same AI voice agent to communicate with a guest in Berlin or a vendor in Tokyo.
Automated RSVP and Preference Management: The most time-consuming administrative tasks for planners are often confirming RSVPs and collecting guest preferences. The Synthesys AI voice agent allows guests to confirm attendance, choose meal preferences (e.g., "I'd like the vegetarian option"), or update contact details directly over the phone. This data is automatically logged into the event management system, eliminating manual data entry and reducing the risk of errors.
Last-Minute Changes Without Chaos: The nature of live events is that things change. When schedules shift, rooms change, or unexpected weather disrupts outdoor plans, an AI voice agent can instantly deliver critical updates to every affected guest. This proactive communication preempts hundreds of inbound calls and prevents on-site confusion, which is a major source of negative attendee experiences.
Data-Driven Personalization: By integrating with a planner's existing CRM and event management software (like Cvent or Eventbrite), Synthesys tailors messages based on a guest's profile. VIPs can receive a more personal, white-glove update about a special pre-event reception, vendors can receive specific operational instructions for load-in times, and general attendees can receive relevant session alerts based on their registered interests.
Competitive Edge
In the crowded event technology market, competitive differentiation is everything. Synthesys provides a distinct and strategic edge by fundamentally rethinking the guest communication model.
Owning the Pre-Event Window: A guest’s impression of an event begins long before they walk through the doors. With Synthesys, every touchpoint—from the initial confirmation call to event reminders and last-minute updates—is not just timely, but also consistent and perfectly on-brand. While competitors might still be relying on email campaigns that get lost in spam folders, you’ve already confirmed attendance and built a relationship with a human-sounding voice.
Reducing Staff Load While Improving Experience: Instead of dozens of staff members making repetitive calls or fielding the same questions, Synthesys automates these routine communications. This frees up the human team to focus on high-touch, complex interactions, like nurturing key sponsors, handling delicate VIP requests, or troubleshooting on-site logistics. The result is a more efficient team and a more personalized, human-centered experience where it matters most.
Real-Time Event Support: The chaos of an event day often includes a flood of inbound calls. Synthesys provides a dedicated phone line that guests can call for information. The AI agent answers instantly, intelligently directing guests to the right session, providing directions to the nearest restrooms, or escalating a specific issue to the appropriate on-site staff member. This ensures a frictionless experience for every attendee.
Seamless Tech Integration: Synthesys is designed to be system-native, not a stand-alone tool. It connects directly and seamlessly to leading platforms like Cvent, Eventbrite, and HubSpot. This deep integration ensures that data flows without manual entry, and that the AI’s communication is always based on the most up-to-date information, from attendee lists to room change updates.
A thorough analysis reveals Synthesys’s position as a market leader, as well as the strategic considerations for continued growth.
Strengths: Synthesys offers a sub-second response time and the ability to handle a theoretically unlimited number of concurrent calls, a scalability unmatched by human teams. The platform’s core strength lies in its multilingual and sentiment-aware voice, which allows for a deeply personalized engagement that adapts to the guest’s tone and mood. Critically, it has direct, two-way integration with major event management software, ensuring that communication is always based on the latest data. The ability to clone a company's brand voice ensures consistent, on-brand messaging across every guest touchpoint. Finally, every interaction is fully logged and auditable, providing a valuable record for post-event analysis.
Weaknesses: The primary challenge is the initial setup and change management. While the platform is designed to be intuitive, creating effective AI conversation flows requires an upfront investment of time and thought. Teams accustomed to manual processes must be trained to embrace this new workflow. The performance of the AI is also directly dependent on the quality of data within the event management system, so poor data hygiene can lead to suboptimal outcomes.
Opportunities: The potential for expansion is vast. Synthesys could offer fully automated VIP concierge services, handling exclusive requests and specialized updates for high-value guests. The platform could be used for proactive upselling, offering event upgrades or add-ons (e.g., a workshop seat, a gala dinner ticket) during confirmation calls. There is also a significant opportunity to expand into adjacent markets like sports events, concerts, and music festivals, where guest communication volume is immense and often chaotic.
Threats: The market for AI-powered communication is growing, and there is a risk of fast-follower platforms from existing event tech competitors who could develop in-house AI tools. This could potentially commoditize some basic features. Furthermore, regulatory shifts around automated calling, such as the FCC’s recent tightening of rules in the U.S. and GDPR in Europe, require constant vigilance to ensure full compliance. The potential for data quality issues from a client’s systems leading to incorrect information being communicated remains a brand risk.
Adopting any new technology comes with a set of predictable barriers. Synthesys is designed to address these concerns head-on, turning potential roadblocks into a smooth implementation process.
Barrier: “Our event has complex guest needs and unique scenarios. A generic AI won't work.”
Synthesys Solution: This is a key concern for any planner who values the guest experience. Synthesys is not a generic AI. It uses conditional logic and a visual, no-code flow builder that allows event teams to program personalized interactions. The AI can be trained to recognize specific keywords and situations, ensuring that special requests, VIP protocols, and accessibility needs are not only addressed correctly but handled with the appropriate tone and professionalism.
Barrier: “My team is already too busy to learn a new, complicated system.”
Synthesys Solution: We understand that a new system cannot become another administrative burden. Synthesys features a no-code, drag-and-drop setup, and comes with a suite of prebuilt event communication templates for common scenarios like RSVP confirmation, venue directions, and last-minute updates. This allows planners to launch the platform and see an immediate return on investment in a matter of days, not months, which is a major factor in driving internal adoption.
Barrier: “Guests will be able to tell it's AI, and that will feel impersonal.”
Synthesys Solution: The days of flat, robotic text-to-speech are a thing of the past. Synthesys uses advanced, proprietary voice cloning and tone adaptation technology that allows the AI to perfectly match a company’s on-brand voice. With nuanced prosody and live sentiment steering, the AI voice is designed to be virtually indistinguishable from a seasoned human coordinator, ensuring that the interaction feels natural, conversational, and genuinely helpful. Our research shows that guests overwhelmingly prefer a quick, accurate AI response to waiting on hold for a human.
Synthesys resolves this by owning the urgency channel with sub-second pickup, ensuring every guest is met with an immediate, human-sounding voice that is ready to act. Unlike competitors who merely log interactions or send templated messages, Synthesys turns conversations into action. Every call is a programmatic event that triggers real-time updates—an RSVP confirmation, a dietary preference change, a room number up Why Synthesys Leads
date—without any human lag. This compresses the distance between information and action to nearly zero, preventing the cascading communication failures that often plague live events.
This deep, system-native orchestration, combined with a relentless focus on emotional intelligence, brand consistency, and unparalleled speed, is why high-growth event planners standardize on Synthesys. It’s not just about saving administrative time; it’s about creating a growth lever that operates at enterprise scale, 24/7, ensuring that every guest feels valued and every event is a seamless success.
