How to Adjust Pauses in IVR Audio

When reading script text aloud, there are times when you want to make the pauses between audio segments longer.

For example, in the case of the generated example, you might feel the need for a pause after mentioning the numbers, such as "Press 1 for consultations regarding new contracts, and 2 for changes to contract details."

In such cases, 『Ondoku』 allows you to create pauses in two ways.

Insert a "。" at the point where you want a pause

"Press 1 for consultations regarding new contracts. Press 2 for changes to contract details."

By inserting a "。" (period) at the point where you want a pause, it will be read aloud with a pause.

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

Script with "。" and "、" inserted:

Thank you for calling. This is the Customer Consultation Desk of XX Corporation. Please follow the voice guidance and press a number. Press 1 for consultations regarding new contracts. Press 2 for changes to contract details. Press 3 for consultations regarding cancellations. Press 4 for other inquiries.

When read aloud, you can synthesize audio like this.

Using Speech Synthesis Markup Language (SSML)

With 『Ondoku』, you can create pauses using Speech Synthesis Markup Language (SSML).

For example,

By writing this, it is possible to create a pause of exactly 1000 milliseconds = 1 second.

When using SSML, it is necessary to write "<speak>" at the beginning and "</speak>" at the end.

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

Thank you for calling. This is the Customer Consultation Desk of XX Corporation.Please follow the voice guidance and press a number. Press 1 for consultations regarding new contracts. Press 2 for changes to contract details. Press 3 for consultations regarding cancellations. Press 4 for other inquiries.

By entering it like this, you can take a long pause of exactly 1 second.

The actual reading will sound like this.

To make a call center automated voice response system more comfortable to use, it is important to finely adjust how pauses are taken in the audio.

We explain how to use Speech Synthesis Markup Language (SSML) in this article, so please take a look!

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

How does IVR work? How is the automated voice played?

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

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

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

By having the caller operate the phone buttons according to the automated voice, calls can be distributed to specific persons or departments.

IVR is an abbreviation for "Interactive Voice Response," and in Japanese, it is called "Automated Voice Response System" or "Automatic 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 follow the voice guidance and press a number. Press 1 for consultations regarding usage, 2 for repairs and replacements, and 3 for other consultations.

This kind of automated voice response guidance is played.

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

The number of companies introducing IVR is increasing rapidly. What are the features and merits of automated voice response?

Recently, the number of companies introducing IVR is increasing rapidly.

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

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

By introducing IVR, automated voice responses can handle all calls, allowing for efficient phone response 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 responses can handle calls outside of business hours, allowing for more detailed customer support.

IVR Becomes More Accessible with AI Voice Synthesis Technology

Another reason IVR is becoming more widespread is that AI voice synthesis technology has evolved significantly.

Previously, automated voice responses could only read aloud in unnatural, robot-like voices, but with the latest voice synthesis software, natural, human-like reading has become possible.

Since free and low-cost text-to-speech apps and software have appeared, introducing IVR and automated voice response systems has become much easier than before.

If you are introducing IVR now, we recommend creating text-to-speech audio with the latest AI voice synthesis apps or software.

Referring to the creation method explained in this article, why not try building a call center automated voice response system with 『Ondoku』?

Introducing Applications and Usage Scenarios of IVR (Automated Voice Response System)

IVR (Automated Voice Response System) is utilized in various situations.

Here are specific applications and usage scenarios.

Introducing IVR to Corporate Call Centers and Customer Consultation Desks

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, a text-to-speech voice created with voice synthesis software responds first.

By introducing IVR to corporate call centers and customer consultation desks, phone inquiry content can be sorted in advance.

This allows calls to be connected to operators with specialized knowledge for each inquiry content, thereby shortening customer wait times.

Also, when call center lines are busy, it is possible to play an announcement saying, "The lines are currently busy."

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

By utilizing free AI voice synthesis software and apps, it has become possible to easily create automated voices for call centers at a much lower cost than before.

Since small companies, offices, and organizations can also introduce IVR, using AI voice synthesis software and apps is recommended for future automated voice response systems.

Automated Voice Response Systems are also Recommended for Reservation Systems

IVR can be utilized for reservation handling at hospitals, accommodations, restaurants, beauty salons, etc.

By creating text-to-speech audio with an AI voice synthesis app and introducing IVR, you can accept reservations via automated voice response 24 hours a day.

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

In a situation where labor shortages are an issue, handling phone reservations is a significant burden for staff.

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

Utilizing IVR for Municipal Inquiry Counters, Administrative Services, and Disaster Information

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

Calls made to municipal counters can be automatically transferred to the appropriate department using IVR.

Furthermore, routine procedures can be automated with automated voice response, such as oversized trash collection reservations or checking the application status of various certificates.

During disasters, IVR automated voice response can be used to provide guidance on evacuation center information, water supply locations, and safety information.

Especially in situations where a rapid response is required, such as disasters, AI voice synthesis software and apps that can create audio immediately are useful.

The ability to respond when many residents call simultaneously is another reason why IVR is suitable as a means of information provision in emergencies.

Parcel Redelivery Requests are a Common Application for IVR Automated Voice Response

Parcel redelivery request call centers are another representative scenario where IVR using automated voice response is used.

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

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

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

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

Recently, due to increased demand for international mail order, there have been successive new entries into the parcel delivery business.

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