What Is an Immersive Phone Call? 24

Immersive phone call

With advances in IVAS (Immersive Voice and Audio Services) technology, the idea of an immersive phone call is a major step forward in the fast-changing world of telecommunications. IVAS technology, a key feature of the next 5G Advanced standard, is poised to completely transform voice communication by providing high-quality, real-time immersive audio across a range of connected devices, including PCs, tablets, and smartphones.

In this article, we will learn in detail about what an immersive phone call is.? What is IVAS technology? How does immersive audio work? etc

By providing a three-dimensional audio experience, IVAS technology improves communication. By creating the impression that the caller is physically present with you, this immersive audio transcends the conventional boundaries of phone calls.

Who made the world’s first Immersive phone call?

The new IVAS codec technology, which is a component of the impending 5G Advanced standard, was shown in a live immersive audio and video chat that was conducted by Nokia’s President and CEO, Pekka Lundmark, and Stefan Lindström, Finland’s Ambassador of Digitalization and New Technologies. Lundmark showcased the improved three-dimensional audio experience that IVAS technology offers during the call, which was conducted from Nokia’s Espoo campus.

Lundmark also showed off the unique acoustic dimensions made possible by it. With its more realistic and immersive audio and video calling experience, IVAS has the potential to revolutionize the telecommunications industry, as demonstrated by this milestone.

With voices emanating from particular directions, the experience is similar to having a face-to-face chat and provides a spatial awareness that enhances the interaction’s authenticity and depth.

This development is especially noteworthy in light of 5G networks, which offer the low latency and bandwidth required to enable such high-end audio experiences. IVAS transforms phone conversations into immersive experiences that can mimic in-person interactions rather than just being a means of voice communication.

Immersive Phone Call technology has the potential to revolutionize a number of applications, including virtual events, business meetings, remote collaborations, and personal interactions.

What is IVAS technology?

Immersive Voice and Audio Services, or IVAS, is a cutting-edge technology that offers high-quality, real-time immersive audio across a variety of connected devices, including PCs, tablets, and smartphones, to improve audio experiences. It is a crucial part of the forthcoming 5G Advanced standard, which intends to use 5G networks’ capabilities to transform communications.

What is an immersive phone call?

Immersion calls improve voice conversations by utilizing immersive audio technologies. Immersion calls use three-dimensional audio, as opposed to conventional phone calls, which use flat, monophonic, or stereophonic sound delivery. Conversations feel more authentic and interesting when you have the impression that the person on the other end is physically present. Immersion calls provide more spatial qualities to the audio, which enhances context and clarity, especially in situations with multiple speakers, like conference calls, when it can be difficult to discern between speakers.

How does immersive audio work?

A three-dimensional soundscape imitating authentic auditory experiences is produced via immersive audio technology. It creates a virtual space with sound sources positioned all around the listener by employing sophisticated spatial audio algorithms. Accurate audio signal processing is used to create this illusion, adjusting sound timing, loudness, and frequency to mimic distance and direction.

Instead of the audio coming from a single, static source, the listener sees the sounds as coming from specific spots around them. A crucial component of this technology are Head-Related Transfer Functions (HRTFs), which simulate how sound enters the human ear from different angles to produce a more realistic and genuine-sounding auditory experience.

What Is an Immersive Audio Experience?

A rich, multidimensional sound environment is created for the listener by an immersive audio experience. By presenting sounds in a three-dimensional area surrounding the listener, this kind of experience transcends traditional stereo or surround sound. It enhances various activities including gaming, virtual reality, movies, and live events, and can be experienced through speakers, headphones, or VR headsets.

As a result, the listener experiences a greater sensation of presence and engagement, feeling more like a participant in the activity than a bystander.

What Is the Difference Between Spatial and Immersive Audio?

Sound that appears to originate from a particular spot in three dimensions is referred to as spatial audio. By giving audio direction and contextual relevance, it improves the audio’s realism. On the other hand, immersive audio is a more general term that includes spatial audio as well as other methods that produce a feeling of depth and surroundings.

While immersive audio focuses on generating a complete aural environment that surrounds the listener and provides a fully immersive experience, spatial audio is more concerned with directionality.

What Is the Difference Between Surround Sound and Immersive Sound?

A multi-channel audio system that uses many speakers positioned throughout the room is called surround sound, and its purpose is to surround the listener with sound coming from all directions. This idea is furthered by immersive sound, which adds a vertical dimension in addition to directional audio to produce a 360-degree sound field. As a result, sounds may now be heard surrounding the listener as well as from above and below, providing a more immersive and natural listening experience.

Additionally, sophisticated audio processing methods that improve realism and presence above and beyond what conventional surround sound systems can do are frequently incorporated into immersive sound.

What are the immersive sound formats?

Immersion sound formats are specialized audio formats made to produce crystal-clear, three-dimensional audio. For instance, Auro-3D, DTS, and Dolby Atmos are examples. With the help of object-based audio, which is supported by these formats, sound designers can precisely control the position and movement of individual sound pieces in 3D space.

In a home theater, movie theater, or on headphones, this produces a more lively and lifelike audio experience.

Who invented immersive audio?

Many companies and researchers have contributed to the evolution of immersive audio over the years. Dr. Amar Bose, the creator of Bose Corporation, was one of the first people in the field of spatial audio. He invented methods for reflecting sound to give the impression of space.

Immersive audio technology has advanced in large part for companies like Dolby Laboratories and DTS, especially with the release of the DTS and Dolby Atmos formats. These developments have had a big impact on how we listen to audio across a variety of mediums.


Realistic and captivating interactions are made possible by immersive audio, which is a major improvement in the way humans perceive sound. This technology has the power to change a lot of things in our daily lives, from making phone calls better to building realistic virtual environments.

Whether in virtual experiences, communication, or entertainment, immersive audio promises to get us closer to the feeling of actual presence as it develops.

What is the IVR call process?

IVR is a technology that call centers utilize to help support workers give more efficient and better phone service. While sophisticated IVRs use speech-to-text voice recognition technology, standard systems let users respond to prompts using a keypad.

Where is IVR used?

Both voice over IP (VoIP) and public switched telephone networks (PSTN) support IVR usage. The following elements are commonly found in an interactive voice response phone system: internet and intranet connectivity using a TCP/IP network.

What is the flow process of IVR?

The caller hears audio prompts during the play step. The call is terminated with the hangup step. Depending on the menu choice, the transfer step routes the call to a certain location. The caller is transferred to a different section of the IVR workflow via the go-to step.
