# Artificial voice has developed strongly in the 4.0 era

Artificial voices are developing rapidly. Over the past few years, businesses have learned to use AI to create artificial voices. Then use them to make promotional videos for businesses, virtual assistants and video game characters. Typically, businesses have relied on text-to-speech (TTS) services to generate voiceovers. The right voices to reflect the personality of the brand. Their purpose is to create spoken content.

For example, message snippets will be faster and less expensive. By relying on machines instead of recording MCs. Some voices still don't show human-like intonation. However, in a recently published MIT Technology Review article discussing, advances in AI are making those limitations disappear.

What is artificial voice?
Artificial voice technology is one of the core technologies of the voice communication era VUI (Voice User Interface) in the 4.0 revolution.

An artificial voice is a machine-generated voice that learns and reconstructs a human voice. Artificial voice generation technology is known for speech synthesis technology. Also known as text-to-speech technology (Text To Speech).

Artificial voices now have natural intonation, are diverse in regions, and are easy to integrate with any system.

In the world, the technology of creating artificial voices has been studied for several decades. Especially thrive in the last 10-15 years. Text To Speech has developed almost completely abroad. Especially in countries where English is used, it brings many practical values ​​in business and life such as:

- Automated customer care switchboard system

– Virtual assistant

– Integration into public transport systems, healthcare, smart cities, smart phones, ..

– Text-to-speech

Demand for artificial voice
Easy-to-use artificial intelligence voice generator. Allow the whole society to develop voice content. Allow the disabled community to self-produce content and access information like normal people.

It also changes the form as the content. Instead of having to record by real people like now for each news and content. The system brings a new experience of news production, content based on machine learning technology of text-to-speech.

artificial voice market

It is forecasted that from 2016 to 2022, the artificial voice market is constantly growing. In all fields such as electronics, finance, healthcare, education, etc. This technology is considered to bring new and more attractive services. Not only with suppliers but also with consumers.

Not out of that trend, in Vietnam, artificial intelligence voice construction technology is predicted to develop rapidly. The technology of building artificial voices is predicted to develop rapidly. Because the digital transformation is being promoted. Smartphones are widely used and 5G broadband will explode.

How to create an artificial voice
Currently, with the development of technology, there are many ways to create artificial voices. However, the most popular methods are: Contextual Voice Generation, Synthetic Dataset, Synthetic Voice

Contextual artificial voice
Currently, businesses are quite satisfied with this technology although it is still a bit stiff. But for the applications it offers, the artificial voice still meets most of the standard speech requirements. With built-in technologies, today's advancements in AI have made voices much more human, Voices more expressive and nuanced.

how to create artificial voice

Businesses that are adopting TTS are gradually adopting artificial voices in a number of areas. Such as in manuals and advertisements. Example: In 2017 KFC celebrated National Fried Chicken Day by recreating the driving experience with an emulation of KFC's international icon, Sanders.

During the campaign, users like to be ordered with Sanders. The campaign used speech recognition, AI and TTS and to generate voice audio. It created the voice of the KFC operator. TTS helped inject character and humor into a global brand by creating a playful experience.
