The growing adoption of voice assistants is anticipated to drive the expansion of the speech technology market in the future. A voice assistant is a digital tool that recognizes voice commands, processes language, and generates voice output. As a crucial element of speech technology, voice assistants allow for hands-free device control and promote natural language interactions, thereby improving user convenience and accessibility across various applications. For example, a report from Vixen Labs, an app development studio based in England, revealed that in June 2022, the use of voice assistants like Google Assistant in the United States rose significantly, reaching 34% in 2022, up from 24% in 2021. Thus, the increased utilization of voice assistants is propelling the growth of the speech technology market.

Leading companies in the speech technology market are intensifying their efforts to create technologically advanced solutions, such as text-to-speech (TTS) APIs, to enhance naturalness and expressiveness. A Text-to-Speech (TTS) API converts written text into spoken words using synthetic speech, offering various voice options and customization features for more natural audio output. For example, in March 2024, Deepgram, a US-based AI company, introduced Aura, a TTS API tailored for real-time, conversational voice AI agents. Aura boasts 12 human-like voices, provides low latency of under 250 milliseconds for rapid responses, and is competitively priced at $0.015 per 1,000 characters. This API allows developers to create applications that facilitate natural conversations with users, making it particularly suitable for industries like customer service and healthcare. Additionally, Aura seamlessly integrates with Deepgram's Nova-2 speech-to-text API, delivering a comprehensive solution for developing sophisticated voice AI interactions.

In March 2022, Microsoft Corporation, a prominent US-based technology company, successfully acquired Nuance for a significant sum of $19.7 billion. This acquisition is poised to expedite Microsoft's industry-specific cloud strategy, particularly in transforming outcomes-based Artificial Intelligence (AI) in sectors such as healthcare, financial services, retail, and telecommunications. Nuance Communications, the acquired entity, is a distinguished US-based speech technology company, further strengthening Microsoft's position in the rapidly advancing field of speech technology.

The speech technology market includes revenues earned by entities by providing services such as speech recognition, voice recognition, speaker identification, speaker verification, automatic speech recognition, and text-to-speech technologies. The market value includes the value of related goods sold by the service provider or included within the service offering. Only goods and services traded between entities or sold to end consumers are included. The speech technology market consists of sales of microphones, speakers, and headsets. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD, unless otherwise specified).

Speech technology is a form of computational technology that utilizes voice recognition and speech synthesis technologies to facilitate machine understanding and response to human speech. It improves communication between humans and machines by enabling voice commands for virtual assistants, enabling hands-free operation in vehicles, and offering accessibility features such as speech-to-text across various applications.

Speech technology comes in two primary forms such as artificial intelligence (AI) and non-artificial intelligence. AI-based speech technology involves leveraging artificial intelligence, machine learning, and language models to empower computers in comprehending, interpreting, and generating human speech. This versatile technology can be deployed in diverse modes, including cloud, on-premises, or embedded, and finds applications across various sectors such as automotive, consumer, government, enterprise, healthcare, and banking, financial services, and insurance (BFSI).
