How to adjust pauses in IVR audio

When reading script text aloud, you may want to have longer intervals between sounds.

For example, in the generated example, you might feel like taking a pause after the part where the number is given, such as "Press 1 for consultations regarding new contracts, 2 for changes to contract details."

In such cases, "Ondoku" allows you to add pauses in two ways.

Insert a "。" where you want to pause the audio

「新規ご契約についてのご相談は1を。ご契約内容の変更については2を。」

By inserting a "。" (full stop) where you want to add a pause, as shown above, you can read it aloud with pauses.

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

Script with "。" and "、" inserted:

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

When you read this aloud, you can synthesize audio like this.

Use Speech Synthesis Markup Language (SSML)

In "Ondoku", you can use Speech Synthesis Markup Language (SSML) to add pauses.

For example,

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

When using SSML, you need to write "" at the beginning and "" 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 Co., Ltd.Please press a number according to the voice guidance. For consultations regarding new contracts, 1. For changes to contract details, 2. For consultations regarding cancellations, 3. For other inquiries, press 4.

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

When actually read aloud, it sounds like this.

To make a call center's automated voice response system more comfortable to use, it is important to finely adjust the timing of pauses in the audio.

The usage of Speech Synthesis Markup Language (SSML) is explained in this article, so please take a look!
