Currently, our lines are very busy. We apologize for the inconvenience, but please stay on the line or try calling back after a while.

2. Read the Script Text Aloud on the 『Ondoku』 Website

Once the script is ready, read it aloud on the 『Ondoku』 website.

After opening the 『Ondoku』 top page, paste the script text into the text box.

At this time, it is recommended to input one segment of audio at a time, such as "when the call first comes in" or "when connecting to an operator."

After entering the script, select the language and voice type.

In 『Ondoku』, for Japanese, you can read aloud with over 16 types of voices, including female, male, and children!

As an example, we will use the female voice "Nanami (Guidance)," which is perfect for IVR automated voice response.

In such cases, 『Ondoku』 allows you to take pauses using two methods.

Insert "。" (period) where you want a pause

"For inquiries regarding new contracts, press 1. For changes to contract details, press 2."

By inserting a "。" (period) where you want a pause, the system will read it with a pause.

Also, by inserting a "、" (comma), you can take a shorter pause.

Script with "。" and "、" inserted:

Thank you for calling. This is, XX Corporation, Customer Consultation Desk. Please press a number, according to the voice guidance. For inquiries regarding new contracts, press 1. For changes to contract details, press 2. For cancellation inquiries, press 3. For other inquiries, press 4.

When read aloud, you can synthesize audio like this:

Use Speech Synthesis Markup Language (SSML)

In 『Ondoku』, you can use Speech Synthesis Markup Language (SSML) to take pauses.

For example, by writing:

you can take a pause of 1000ms = exactly 1 second.

When using SSML, you must write 「」 at the beginning and 「」 at the end.

For example, if you want to take a longer pause after "Customer Consultation Desk." in the current script:

Thank you for calling. This is, XX Corporation, Customer Consultation Desk.Please press a number according to the voice guidance. For inquiries regarding new contracts, press 1. For changes to contract details, press 2. For cancellation inquiries, press 3. For other inquiries, press 4.

By entering it like this, you can take a long pause of exactly one second.

What is IVR (Automated Voice Response System)? Explaining the Mechanism and Features

From here, we will explain the basic mechanism and features of IVR (Automated Voice Response Systems).

What is the Basic Mechanism of IVR? Responding to Customer Calls with Automated Voice

IVR (Automated Voice Response) is a system that responds to calls coming into a call center by playing audio.

By having callers operate phone buttons according to automated voice instructions, calls can be distributed to the appropriate personnel or departments.

IVR is an abbreviation for "Interactive Voice Response," and in Japanese, it is called "Automated Voice Response System" or "Automated Response Voice System."

The mechanism of IVR is very simple.

When a customer calls a company's phone number, the IVR (Automated Voice Response System) first responds automatically.

Thank you for calling. This is XX Corporation.

Please press a number according to the voice guidance. For consultation on how to use, press 1. For repairs or exchanges, press 2. For other consultations, press 3.

Automated voice response guidance like this is played.

When the customer presses a button on the phone, the IVR system recognizes the number input and transfers the call to the appropriate department or call center operator.

The Number of Companies Implementing IVR is Growing. What are the Features and Benefits of Automated Voice Response?

Recently, the number of companies implementing IVR has been increasing rapidly.

The biggest reason is to solve the problem of labor shortages.

Call center operators are chronically in short supply, and the difficult situation for recruitment continues.

By implementing IVR, all calls can be handled through automated voice response, making it possible to respond efficiently with limited personnel.

Another reason is the ability to improve customer service.

Customers expect to be able to inquire with companies 24 hours a day.

With IVR, automated voice response can handle calls outside of business hours, allowing for more detailed customer support.

IVR Becomes More Accessible with AI Speech Synthesis Technology

Another reason IVR is becoming even more widespread is the significant evolution of AI speech synthesis technology.

In the past, automated voice response could only read aloud in unnatural, robot-like voices, but the latest speech synthesis software has made natural, human-like reading possible.

Because text-to-speech apps and software that can be used for free or at a low cost have appeared, implementing IVR/Automated Voice Response Systems has become much easier than before.

IVR (Automated Voice Response Systems) are utilized in various situations.

We will introduce specific uses and scenarios.

Implementing IVR in Corporate Call Centers and Customer Service Windows

The most common use of IVR is in corporate call centers and customer consultation desks.

When you call the customer support of a large company, in most cases, read-aloud audio created with speech synthesis software responds first.

By implementing IVR in corporate call centers and customer consultation desks, phone inquiries can be sorted in advance.

As a result, calls can be connected to operators with specialized knowledge for each inquiry type, which shortens customer wait times.

Also, when call center lines are busy, it is possible to play a message saying, "Our lines are currently busy."

While there is a limit to the number of calls an operator can handle, by utilizing AI speech synthesis software and automated voice response systems, any number of calls can be received simultaneously.

By utilizing AI speech synthesis software and apps that can be used for free, it has become possible to casually create automated voices for call centers at a much lower cost than before.

Since IVR can be implemented even in small companies, offices, and organizations, it is recommended to use AI speech synthesis software and apps for future automated voice response systems.

Automated Voice Response Systems are also Recommended for Reservation Systems

IVR can also be utilized for taking reservations at hospitals, accommodations, restaurants, beauty salons, etc.

By creating read-aloud audio with an AI speech synthesis app and implementing IVR, reservations can be accepted 24 hours a day through automated voice response.

By having customers input the date and time using phone buttons according to the automated voice response guidance, information can be automatically registered in a database to accept the reservation.

Amidst labor shortages becoming a problem, taking phone reservations is a significant burden for staff.

By creating read-aloud audio for automated voice response with AI speech synthesis software and apps, it is possible to improve the labor environment for staff and increase customer satisfaction.

Utilizing IVR in Municipal Inquiry Windows, Administrative Services, and Disaster Information

IVR (Automated Voice Response Systems) are also widely used by local governments such as city and ward offices.

Calls made to municipal windows can be automatically transferred to the appropriate department utilizing IVR.

Additionally, routine procedures can be automated through automated voice response, such as bulky waste collection reservations or checking the application status of various certificates.

In times of disaster, IVR automated voice response can also provide guidance on evacuation center information, water supply locations, safety information, etc.

Particularly in situations where a prompt response is required, such as disasters, AI speech synthesis software and apps that can create audio immediately are very useful.

Being able to handle cases where many residents call at the same time is another reason why IVR is suitable as a means of information provision during emergencies.

Delivery Redelivery Requests are a Common Use for IVR Automated Voice Response

Call centers for requesting redelivery of packages are a representative scenario where IVR utilizing automated voice response is used.

When you call a delivery company, an automated voice plays through the IVR.

Recently, customers can complete redelivery procedures simply by inputting the number stated on the slip using their phone.

Since IVR eliminates the need for a call center operator to respond, it also helps solve labor shortages for delivery companies.

Unlike before, customers no longer need to wait until they are connected to a call center operator, making it easier to request redelivery 24 hours a day.

Recently, with the increase in mail-order demand from overseas, there have been successive new entries into the delivery business.

If you are building a new redelivery acceptance system, it is recommended to implement an automated voice response system utilizing AI speech synthesis services.

Eliminating wait times when being transferred because a call was made to the wrong department is also a major benefit.

Inquiries and Phone Reception are Possible 24/7 with Automated Voice Response

The ability to inquire 24 hours a day is also a major benefit of IVR.

By implementing an automated voice response system, customers can call at their own convenience without worrying about business hours.

Even when calling late at night or early in the morning, basic information such as business hours and regular holidays can be obtained through automated voice response.

In the case of sudden temporary closures, you can create audio with AI speech synthesis software and inform customers of the closure through automated voice response.

IVR also has Benefits for Privacy Protection

IVR also has benefits in terms of privacy protection.
