What it is
Voice AI encompasses technologies that allow computers to interact with humans using spoken language. This includes automatic speech recognition (ASR), which converts spoken words into text, and natural language understanding (NLU), which interprets the meaning of that text. It also includes natural language generation (NLG) and text-to-speech (TTS), which convert text back into spoken language. Voice AI systems are trained on vast datasets of human speech and text to improve accuracy and naturalness.
Voice AI is ubiquitous, powering virtual assistants like Amazon Alexa and Google Assistant, customer service chatbots, and voice interfaces in cars and smart devices. Its increasing sophistication impacts how consumers interact with technology and how businesses automate communication. Developments in voice AI are closely watched by investors interested in the smart home market, customer experience technology, and accessibility solutions. Understanding voice AI helps retail investors recognize the underlying technology driving many popular consumer products and enterprise solutions.
