[Event Management] AI voice is recommended for guidance and crowd control announcements! Solving part-time staff shortages.
Jan. 26, 2026

For event organizers of things like music concerts, sports matches, exhibitions, and lectures, the task of organizing the flow of people through guidance is a very difficult problem, isn't it?
Until now, it was common practice to place part-time staff with megaphones in various locations to give instructions in a loud voice.
However, that method places a heavy burden on the staff, and gathering part-time workers just for guidance is also a challenge.
In this article, we will introduce tips for reducing the burden of event guidance and call-outs to run a venue smoothly with fewer people!
The biggest secret is to utilize a text-to-speech service.
Since you can provide guidance in foreign languages like English as well as Japanese, it is also ideal for managing international events.
We will also introduce specific guidance and call-out methods using AI text-to-speech services, so why not refer to this article to solve your event management problems?

What Are the 3 Reasons Why Event Guidance and Call-out Announcements Are Difficult?

When managing an event, guiding participants and making call-outs are very difficult issues.
Not only might participants be unable to enjoy the event comfortably, but if guidance and call-outs aren't handled appropriately, safety issues and other troubles could also occur...
There are three main reasons why guidance and call-outs are difficult in event management.
1. It is difficult to share guidance and call-out tips with part-time staff
The biggest problem with event guidance and call-outs is that it is difficult to share tips and know-how with part-time staff.
Most guidance and call-out staff for events such as music concerts, sports matches, exhibitions, and lectures rely on part-time or temporary staff.
While veteran staff can provide smooth guidance by choosing the right words while observing the situation, event management often involves a large number of part-time workers who are entering the site for the very first time that day.
Furthermore, because they are often day laborers for a single day, it is frequently difficult for them to achieve easy-to-hear vocalization or call out in a tone that doesn't make customers feel uncomfortable.
Also, the fact that the content of announcements changes subtly depending on the person is a major issue.
The larger the scale of the event, the more staff and part-time workers are involved, making it difficult to share guidance tips with everyone.
2. Long hours of guidance and call-outs are a heavy burden for part-time staff
The heavy burden on part-time staff is another reason why event guidance and call-outs are difficult.
Events such as music concerts, sports matches, exhibitions, and lectures can range from those that finish in a few hours to those that last for long hours from morning to night.
During that time, staff in charge of guidance must constantly stand and repeatedly shout the same announcement content.
It is not uncommon for their voices to give out in the afternoon, preventing crucial guidance announcements from reaching the customers.
From the perspective of staff health management, there are limits to performing event guidance solely through the call-outs of part-time staff.
3. Staff call-outs and announcements don't reach people due to venue noise
Event venues are basically always overflowing with various sounds, such as BGM and talking voices.
In such an environment, even if part-time staff try to guide with their natural voices, the voices often don't reach participants.
When important precautions or guidance announcements aren't conveyed, troubles can occur, such as lines forming in unexpected places or people entering restricted areas.
This can be improved to some extent if part-time staff use megaphones, but even then, the sound is often distorted and hard to hear, or the equipment is difficult to adjust.
Furthermore, preparing megaphones requires the cost of purchasing equipment.
In order to reliably deliver information and achieve smooth guidance, it is necessary to use a means that can reliably deliver clear audio.
Solve Event Guidance and Call-out Problems with AI Text-to-Speech Services!

As you can see, there are several difficult problems to solve regarding event participant guidance and call-outs.
Therefore, we recommend introducing the latest AI services for event guidance and call-outs.
You can solve problems with event guidance, call-outs, and announcements all at once, from the management of the event day to the recruitment of part-time staff.
Achieve effective event guidance and call-outs with AI text-to-speech services
If you want to perform event guidance and call-outs more effectively and efficiently, it is recommended to use an AI text-to-speech service.
With an AI text-to-speech service, you can create and save audio files that are as easy to hear as announcements recorded by professional narrators, perfect for event guidance and call-outs!
The biggest merit of using an AI text-to-speech service is that the quality of event guidance and call-outs can be completely unified.
Until now, there was inevitably a difference in the volume and clarity of guidance and call-outs between veteran and new part-time staff.
But with AI voice, you can always announce with a constant volume and clarity, and with clear vocalization like a professional narrator.
Voices won't get quieter due to fatigue, and you can continue guidance and call-outs with always easy-to-hear and polite audio.
Also, because you can manage the content of guidance and call-outs as text, you can prevent troubles where what is said differs depending on the staff before they happen.
Solve recruitment problems for guidance and call-out part-time staff!
Using an AI text-to-speech service can also solve the recruitment problems of part-time staff for event guidance and call-outs.
When managing an event, it is very difficult to gather part-time staff for guidance.
As labor shortages become more serious, recruiting temporary part-time staff, which used to be easy, is becoming more difficult every year.
The risks of part-time staff canceling on the day or being late are also always present.
Many event managers have likely had the experience of struggling with staff placement on the day because the required number of people didn't show up.
In such cases, if you utilize an AI text-to-speech service, you can reduce the number of part-time staff required for event guidance and call-outs.
It is as simple as replacing locations where people previously stood to call out guidance with speakers playing audio created with an AI text-to-speech service.
The staff will only need to handle emergency responses or answer individual questions.
Since you can reduce staff management tasks, you will be able to manage events more efficiently.
Of course, by reducing the number of part-time staff hired, you will be able to run the event at a lower cost by saving on personnel expenses.

What Are the Tips for Creating Event Guidance and Call-out Audio with AI Services?
If you use an AI text-to-speech service to create event guidance and call-out audio, we recommend keeping a few tips in mind.
A tip for conveying information to participants more effectively is to be conscious of the "pauses" in the text.
Before conveying something important, you usually pause for a moment or take a breath, right?
When making event guidance and call-out audio with AI, it is important to create audio with an easy-to-hear rhythm by including more commas and periods, or by using "SSML tags" to adjust the audio.
Tips for taking "pauses" in audio with the AI text-to-speech service Ondoku are introduced in this article, so please take a look!
Choosing audio that matches the atmosphere of the event is also a tip for creating easy-to-hear guidance and call-out audio.
For a fun festival, choose a bright and energetic voice; for a calm exhibition or a solemn ceremony, we recommend choosing a lower, calmer voice.
By using audio that fits the scene, you can convey information to event participants more smoothly.
Also, instead of starting to speak audio suddenly, including a chime sound at the beginning is another tip.
In this way, simply by being conscious of a few tips, you can more effectively call out to and guide event participants with AI voice.
With Ondoku, you can easily create audio files as many times as you like while listening, so it is also recommended to make several audio files while imagining how they will sound at the actual site and choose the best one.
English and Foreign Language Guidance/Call-outs Are Also Important for Event Management

In future event management, guidance and call-outs in English and other foreign languages will also be important.
It is recommended to produce English and foreign language announcement audio using an AI text-to-speech service as well.
Guiding event participants in English or foreign languages is very difficult
As globalization progresses, the number of overseas participants in events such as music concerts, sports matches, exhibitions, and lectures is increasing.
However, until now, it has been very difficult to provide guidance or call out to event participants from overseas in English or other foreign languages.
It was hard to find part-time staff with language skills such as English, and hiring personnel with language skills required high labor costs.
As a result, until now, guidance and call-out announcements could only be made in Japanese, leading to cases where foreign participants got lost or troubles occurred because they couldn't understand the rules.
Solve event English guidance and call-outs with AI text-to-speech services
But it's okay!
Guiding and calling out to event participants from overseas can also be easily solved by utilizing AI text-to-speech services.
You can create easy-to-hear audio with native pronunciation simply by entering English text created with a translation tool into the text-to-speech service.
AI-generated audio is much easier to hear than English pronounced by Japanese staff, so foreign participants will be able to participate in events more comfortably.
Announcement audio for guidance and call-outs can be created in foreign languages other than English
What's more, by using an AI text-to-speech service, you can create guidance and call-out announcement audio in foreign languages other than English.

What Are the Tips for Multilingual Guidance and Call-outs to Event Participants?
There are tips for effectively playing guidance and call-out audio for event participants from overseas at the venue.
The method is very simple.
Create audio data that connects multiple languages, such as Japanese announcements followed by English announcements, and then Chinese announcements.
Then, simply play that audio repeatedly from speakers.
However, if you create separate audio files for each language, such as Japanese and English, it takes time and effort to edit them later.
That's where you want to utilize Ondoku's "SSML tag" function.
With Ondoku, by using "SSML tags," you can read text that contains a mix of multiple languages, such as Japanese and English.
The method for multilingual reading with SSML tags is explained in this article, so please take a look!
The secret to smoothly calling out to and guiding event participants from overseas is to use an AI text-to-speech service.

What Are the Tips for Effective Event Guidance & Call-outs?

Finally, we will introduce tips for performing event guidance and call-outs more effectively!
Tips for Differentiating Between AI Voice Announcements and Part-time Staff Call-outs
The biggest secret to smoothly guiding event participants and making call-outs is to use AI voice announcements and part-time staff call-outs in the right place at the right time.
For example, standardized guidance that doesn't change for anyone, such as calls for ticket checks at the entrance, directions to the restroom locations, or warnings about no smoking, is best left to audio created with an AI text-to-speech service.
Conversely, situations that require judgment, such as individual responses to troubled participants, the occurrence of sudden illness, or organizing unexpected crowds, require responses by part-time staff.
By leaving simple guidance and call-outs to audio created with an AI text-to-speech service, part-time staff can concentrate on tasks that only humans can perform.
In this way, by clearly dividing roles between guidance audio created with an AI text-to-speech service and the call-outs of part-time staff, high-quality event management is possible even with a small number of people.
Prompting participants to prepare with advance announcements is also an important tip
Another important tip for smooth guidance is to call out to participants one step before they take action.
For example, instead of calling out "Please have your ticket ready" right in front of the entrance gate, play an announcement asking for ticket preparation in the aisle dozens of meters before the gate.
That way, participants can get ready while walking and will be able to pass through the gate smoothly.
For this preliminary call-out announcement, playing AI text-to-speech audio through speakers is extremely effective.
"It's not worth placing a staff member, but it would be kind to have guidance."
By playing call-out announcements at such points, you can guide event participants much more smoothly.
Latest AI is Recommended for Event Guidance and Call-outs!
Event guidance and call-outs are indispensable tasks for ensuring the safety and satisfaction of participants.
However, as labor shortages become more serious, it is becoming increasingly difficult to run events using only part-time staff.
As introduced in this article, AI text-to-speech services are ideal for standardized guidance announcements and repetitive call-outs.
With the AI text-to-speech service Ondoku, anyone can easily create high-quality announcements simply by entering text.
We recommend utilizing AI text-to-speech services for future event management.
When you are struggling with event management for music concerts, sports matches, exhibitions, lectures, etc., why not utilize AI text-to-speech audio for participant guidance and call-outs?
We sincerely hope that you can solve the difficult problems of event management, such as participant guidance and call-outs.
