A new revolution has already been announced, even if you have been skeptical about the voice technology before, the figures are quite eloquent. Canalys reported 187% worldwide market growth in smart speaker shipments in the second quarter of 2018 and 137% growth is predicted for the 2019. So a new eon of voice-enabled devices can be regarded open, and the former trend of voice technology implementation can already be acknowledged as a major shift happened in the digital world recently.
Why does the AI Voice Technology Gain popularity?
Every generation is characterized differently, and from the IT trend adoption viewpoint as well. At present, it is the millennials, who are using voice technology much more than other age groups. The eMarketer report claims that practically twice as many millennials interact with voice assistants than Generation X representatives. It's around 30 million vs 15.3 million if compared monthly. The usage gap is predicted to grow even more over the next 3 years.
To figure out the prospects, let's first delve into the history of the technology.

The Evolution of Voice Technology
The first speech recognition systems, IBM's Shoebox and Bell Labs' Audrey, can be traced back to the 1950s. Naturally, they recognized little words and phrases and were limited in their capabilities. Audrie was the first. It recognized only single voice digits spoken aloud. It was initially intended for hands-free dialing on the telephone. Almost a decade later, IBM launched its Shoebox. In addition to digits, it recognized 16 words. As the decades passed, AI voice technology advanced along with computing power, data processing, and new algorithms' development.
In the 1970s, the American DARPA (Department of Defense Advanced Research Project Agency) started the SUR (Speech Understand Research) program. As a result, the “Harpy” speech system was created in 1976. It could understand over 1,000 English spoken words. Still, it was limited in the ability to understand natural language. Also, the first commercial application of IVR (interactive voice response) was launched.
In the 70s-80s years of the previous century, the HMM (Hidden Markov Model) development improved speech recognition significantly. Instead of just looking for familiar sound patterns, HMM considered if the unknown sounds could be words.
90s -2000s brought the introduction of PCs and the advent of the internet. It enabled the more advanced speech recognition systems and voice AI technology development. DragonDictate was the first consumer solution that used discrete dictation methods. However, the user had to pause after each word. In 1997, Dragon Systems released Dragon Naturally Speaking. It was the first continuous speech recognition tool to transcribe speech into texts. Also, the early virtual assistants activated by voice appeared.
Since 2010, the rise of ML and AI in voice technology has enabled the creation of sophisticated systems. The decade started with IBM’s Watson. Then followed Apple's Siri, Microsoft’s Cortana, Amazon's Alexa, and Google Assistant. The technology has skyrocketed in this period. Today we see cutting-edge versatile software products.
However, the launch of GPT chat opens even broader prospects for voice AI systems. They have the potential to improve their capability of complex queries understanding and more human-like responses. It also leads to creating more natural, realistic, and personalized interactions with virtual assistants. It means increased user satisfaction and engagement.
What Makes Voice so Popular?
It’s actually the technology for everyone, which makes the users feel natural. People expect conversations and actions, so their voice queries are often more precise and action-oriented. Daily routines do not prevent the users from accessing their devices and using voice assistants, the latters in their turn can be accessed anywhere and at any moment.
Besides, it’s easily integrated with other devices and powered by Artificial Intelligence, it gets smarter while used. So it does not require developing specific custom applications.
AI Voice Technology — What Actually Is It?
Speaking about Alexa, Bixby, or Siri, we, in fact, speak about the interface, covering multiple software layers, from voice recognition through AI to voice-enabled applications. In fact, voice technology is the combination of IoT (devices and gadgets), AI (services), and UX (interaction) resulting in a hands-free technology which to a great extent still resembles science fiction.
