Component Insights

The software component segment led the market with a revenue share of over 71% in 2021. High penetration of the software segment can be attributed to advancements in increased computing power, information storage capacity, and parallel processing capabilities to supply high-end services. For instance, in January 2021, Amazon Web Services Inc. and Talkdesk, a cloud call center software company, collaborated to provide customers with the freedom, agility, and insight to manage contact center operations and improve customer experience by combining Talkdesk CX Cloud's unique cloud-native capabilities with AWA's extensive AI and machine learning offerings. Moreover, this speech recognition software is used to make audio information available to users and has automatic subtitles for deaf people.

Leading firms in various industries are implementing speech-to-text technologies to deal with the constantly rising video-based material. This aids firms in developing new ways to tap into the massive volumes of data accessible to create new processes, services, and products, giving them a competitive advantage. For instance, in August 2020, Speechmatics, a provider of Autonomous Speech Recognition technology, collaborated with Prosodica Inc., a software development company and provider of audio analysis and innovative voice technology, to offer superior call experiences to improve customer care and enhance customer experiences.

Deployment Insights

The on-premises segment dominates the market with a revenue share of over 59% in 2021. The on-premises deployment model is preferred by sectors related to communication, marketing, HR, legal departments, studios, researchers, and broadcasters, among others, due to security concerns. Furthermore, due to its security and licensing, on-premises deployment is preferred by large corporations and banking institutions. Such security concerns are anticipated to supplement the growth of the on-premises model segment during the forecasting period.

The cloud segment is expected to expand at a significant CAGR of 16.2% from 2022 to 2030. The cloud-based technology provides benefits such as minimum capital requirement and easy deployment, facilitating the adoption of the cloud deployment model. The adoption of a cloud-based model is projected to be encouraged by the COVID-19 pandemic, as social distancing and lockdown practices encourage companies to move to a cloud-based speech-to-text API model that can be operated remotely. Cloud-based speech-to-text software has development potential due to businesses' increasing demand for SaaS services (Software as a Service). Furthermore, the cloud segment of the market is predicted to advance faster, as the demand for cost-effective, scalable, and easy-to-use speech-to-text API solutions further grows.

Organization Size Insights

The large enterprise segment held the largest revenue share of more than 65% in 2021. The major factor propelling the growth of the segment is the high capital stability which allows large enterprises to afford such API integrations. However, during the projection period, the SME segment is expected to advance at a faster rate. Large firms are facing extending competition from developing SMEs, which is driving the segment's expansion.

Speech-to-text API solutions and services demand is predicted to increase at a rapid rate among SMEs throughout the projection period due to the availability of cost-effective cloud solutions. Due to the COVID-19 pandemic, both small and large enterprises are expected to restrict their R&D investments in speech-to-text software and solutions, which may hamper the advancement in speech-to-text technology.

Application Insights

The fraud detection & prevention segment dominates the speech-to-test API technology market with a revenue share of 28% in 2021. This is due to the growing need for speech-to-text APIs in the entertainment and media industry, which convert video and audio content into shareable and searchable text.

The industry is divided into contact center and customer management, content transcription, fraud detection and prevention, risk and compliance management, subtitle generation, and other applications. The content translation that uses technology to improve speech to text, such as machine learning and artificial intelligence, is anticipated to accelerate the expansion of the industry.

The contact center & customer management segment is expected to witness significant growth during the forecast period; this growth can be attributed to the increasing use of contact center technologies to help companies create phone menus through APIs such as community forums, omnichannel self-service capabilities, and interactive speech recognition (IVR). Furthermore, content transcription using developing technologies like artificial intelligence and machine learning improves speech-to-text conversion, which is projected to drive market expansion.

Verticals Insights

The BFSI segment dominates the market, with a revenue share of 29% in 2021. The major factor propelling segment growth is the use of speech-to-text converters to analyze the customer’s feedback. Banks and financial institutions file complaints, address inquiries, and collect feedback from clients daily. Most consumers prefer speaking with an operator rather than typing their questions or browsing through several menus and screens. The speech-to-text converter technology plays an essential role in addressing the customer’s feedback and makes the working of BFSI smooth.
