Voice SMS: how does it work?

When a company decides to launch an SMS campaign, they can choose to convert it into text-to-speech. The text message is then sent as a voice message.

The convenient part is that you don't have to record the message yourself. The voice is generated directly by the computer, and you can select the language and gender of the voice. Sending a voice SMS is a highly effective practice.

Why send voice messages via SMS?

If you are looking for a middle ground between an impersonal text message and a phone call, a voice message is the best option.

Why? Because a simple text message might not convey the right tone. Misunderstandings and confusion are all too common. Conversely, with voice messages, you can send up to 30 seconds of audio. Furthermore, recipients do not need internet access or social media accounts to receive voice messages.

This communication channel can be beneficial for both businesses and individuals.

Voice message: what is its purpose in business?

In short, sending a voice SMS allows for the delivery of important messages via text-to-speech, enabling much smoother and more efficient communication for businesses.

In the professional world, the uses of voice messaging can be summarized into three main areas. While there are many more applications for this communication channel, the most frequent uses relate to authentication, alerts, and assistance for visually impaired individuals.

Using voice SMS for account activation and authentication

Voice messages make it possible to send important information such as access codes, OTPs (one-time passwords), mTANs, etc.

The mTAN (mobile transaction authentication number) is used to confirm banking transactions. It is sent via SMS to provide an extra layer of security for transaction authorization. The voice OTP service, on the other hand, is a sequence of characters or numbers delivered via a phone call. It is most commonly used to verify a transaction or a login. Companies choose this authentication service because of its security, as it is virtually impossible to intercept a voice message.

Using voice SMS for alerts

Alert messages are usually urgent notifications that must not be missed. They can provide information about dangerous weather conditions, natural disasters, evacuations, missing persons, and more. In short, any information that may relate to the recipient's safety—information that is easily conveyed via voice SMS.

Using voice SMS for visually impaired individuals

Sending a voice SMS can also be extremely useful for people who have difficulty reading. The system calls the recipient and reads the message aloud, which is very practical. This is especially true for hospitals, nursing homes, and medical centers, where sending standard SMS or emails is not always the ideal solution. Many patients struggle to read appointment reminders or notifications sent via text. This problem is eliminated by using voice calls.
