What is Voice Messaging?

Voice messaging, also known as Voice Broadcast Messaging (VBM), is a communication technology that allows businesses and governments to send automated voice messages in bulk.

Forget about dialling manually each number or spending hours calling your customers one by one. Voice messaging allows you to send pre-recorded messages to your audiences in a couple of minutes.

Most common voice messaging services involve IVR or text-to-speech (We will explain more about them later!). You can also personalize the message and interact with the recipient through the numeric keypad of their phone, for example, to enter a number to choose an option or enter a sequence of numbers belonging to an ID.

Why integrate a Voice Messaging system?

We are sure that one of your primary concerns right now is how to improve your customer experience. If not, you should start thinking about it.

According to Zendesk, 52% of customers make a special effort to shop for brands they are loyal to. CX drives engagement and satisfaction.

How can businesses do that? With an effective communication strategy.

But there are indeed some challenges. Every communication channel has its cons and pros. SMS has character limits; Emails have a low open rate compared to SMS; WhatsApp it’s not globally accessible.

If you are using phone calls, you probably know that call centres are super expensive to run. When we talk about voice messaging, we go beyond simple phone calls.

Voice communications bring value to your business by helping you navigate all those challenges.

It’s accessible

You can send automated voice calls to every mobile phone globally. It doesn’t need to be a smartphone.

It’s cost-effective

With a response rate of 90%, you can be sure that almost all your customers will listen to your message.

It’s efficient

Thanks to IA, your customers can find the answers to their questions by themselves without the need for any human intervention. This self-service that voice technology allows improves both productivity and engagement.

Considering that 90% of consumers want to receive consistent interactions across multiple channels, we recommend you think of voice messaging as an alternative to SMS or email rather than using it to complement the communication channels you are already using.

By integrating two o more channels into your communication strategy, you can deliver your customers a consistent omnichannel customer experience.

How does Voice Messaging work?

In this busy and fast-paced world, nobody has time to wait on hold in a queue. Also, nobody has the patience to answer too many questions to find a simple answer. That’s why choosing the right automated voice messaging system is key to avoiding customer frustration.

You should find an efficient system which allows you to create a simple but powerful experience. These are some voice messaging key functionalities:

  • Text-to-Speech: This voice functionality allows to write a text and send it via voice. A good voice messaging system should allow businesses to personalize the message, for example, by calling the customers by their names or invoice number. Also, some voice providers incorporate Automatic Speech Recognition in text-to-speech messages and enable automated passwords to be repeated over secure lines to customers.
  • Pre-recorded audio: Is the possibility to deliver pre-recorded audio to your customers and employees when they answer the call. It’s a good option to deliver a more “human” experience and make your customers feel it more personal.
  • Interaction Voice Response (IVR): Thanks to Interactive Voice Response, you can give your recipients the possibility to interact with you during an automated voice call. For example, they can use their telephone keypad to choose an option or enter numerical data.

Voice API

API (Application Programming Interface) is a technology software which allows different applications to work together. With APIs, you can embed communication capabilities into your existing IT systems and CRM without no development from your side.

People use APIs all the time – developers know that – but the rest do not even notice it.

For example, when you are sending instant messages via WhatsApp or Facebook, you are using an API. When Google ask you about your location, it’s a geolocalization API that makes that work. Also, when you are looking for cheap flights on a website and it redirection you to the airline portal.

Most CPaaS providers have low-code communication APIs that allow seamless integration to different mobile channels capabilities without any technical knowledge.

That means you don’t have to invest in a team of developers to create conversational experiences. A Voice API is a particular software designed to add into existing systems voice capabilities such as text-to-speech, pre-recorded audio, IVR, and password delivery.

How Does Voice Broadcasting compare to other communication channels?

Voice Messaging use cases

Combined with other mobile communication channels, such as SMS or WhatsApp, voice can boost productivity and customer engagement. How? By automating tasks like sending due-date payments, reminders, special offers, and more.

Here we will explain the top automated voice messaging use cases your customers will love:

  • Send generic or personalized offers: Build relationships with customers and improve engagement by sending generic or personalized voice calls to share special offers, encourage loyalty, and more.
  • Offer Easy Appointment Management: Send personalized text-to-speech voice calls that provide essential appointment details, like date, time, and appointment location. Enable the recipient to easily confirm, cancel, or reschedule via IVR.
  • Prevent fraud: One-time passwords (OTPs) through a text-to-speech voice call prevent fraud and improve business security. Voice OTP use case is a great option for authentication because the audio can be repeated as many times as you indicate to ensure the recipient understands.
  • Increase Accessibility: Ensure compliance with accessibility regulations, including the ADA Requirements on Effective Communication, by providing communication channels that meet government-mandated accessibility requirements.
  • Get Quick Customer Feedback: Our integration APIs make it easy to survey recipients about the service they receive by generating a voice + IVR call from within your IT system (CRM, ERP).
  • Provide Helpful Reminders: Send generic or personalized voice calls to remind recipients of upcoming payments, expiration dates, and other important details.
