The World of Voice Messaging: Exploring Different Types and Applications


As technology continues to advance, so does the way we communicate. One method that has gained significant popularity in recent years is voice messaging. In this blog post, we’ll explore what voice messaging is and discuss several types of voice messaging systems, including Sigma Voice’s automated voice messaging system, voice messaging on iPhone and Android, and WhatsApp voice messaging.

What is Voice Messaging?

Voice messaging is a communication method that allows users to send short audio recordings to one another instead of using traditional text messages or phone calls. These recordings can be listened to and responded to at the recipient’s convenience, making voice messaging a versatile and efficient option for both personal and professional communication.

Sigma Voice’s Automated Voice Messaging System

Sigma Voice offers an innovative automated voice messaging system that enables organizations to send pre-recorded voice messages to a list of phone numbers within minutes. This Software as a Service (SaaS) platform allows companies to contact customers, employees, or members with ease and efficiency.

Also referred to as mass calling, this system is particularly useful for sending important notifications, reminders, and updates to large groups of people. Whether it’s a school notifying parents about a sudden closure, a political campaign rallying supporters, or a business sharing an exclusive promotion, Sigma Voice’s automated voice messaging system streamlines the communication process and ensures that messages are delivered promptly and accurately.

In addition to its automated voice messaging system, Sigma Voice also offers text to voice messaging, commonly known as text to speech. This feature allows organizations to create dynamic messages that incorporate specific details, such as dates, times, or dollar amounts, by converting written text into natural-sounding speech.

Text to voice messaging is particularly useful for appointment reminders, as it allows businesses to send personalized and timely notifications to clients. For example, a dental office can use this service to remind patients of their upcoming appointments, including the specific date and time. This not only adds a touch of personalization but also helps reduce no-shows and last-minute cancellations. With Sigma Voice’s text to voice messaging, organizations can effortlessly cater to their audience’s needs while enhancing the overall communication experience.

Voice Messaging on iPhone and Android

Smartphones have made voice messaging more accessible than ever, with both iPhone and Android offering native support for this feature. On iPhones, the iMessage app allows users to send voice messages by simply holding down the microphone icon and recording their message. Similarly, Android users can send voice messages through the Google Messages app by tapping and holding the microphone icon.

Voice messaging on smartphones is particularly useful for quick, informal communication. It can help convey tone and emotion that may be lost in text messages, making conversations feel more personal and engaging.

WhatsApp Voice Messaging

WhatsApp, a widely-used messaging platform, has also integrated voice messaging into its service. Like the voice messaging features on iPhone and Android, WhatsApp allows users to record short audio messages that can be sent to individuals or groups. To use this feature, users simply tap and hold the microphone icon within a chat.

WhatsApp voice messaging is popular for its ease of use and ability to send messages across different platforms, as it is available for both iPhone and Android devices. Additionally, with end-to-end encryption, WhatsApp ensures that voice messages remain private and secure.


Voice messaging has come a long way, with various platforms offering unique ways to communicate using audio recordings. From Sigma Voice’s automated mass calling system to voice messaging features on iPhone, Android, and WhatsApp, there is a solution for every communication need. As technology continues to evolve, we can expect voice messaging to become even more versatile and prevalent in our daily lives.
