Speech-to-Text API Market Statistics: 2031

The global speech-to-text API market was valued at $2.4 billion in 2021, and is projected to reach $12.1 billion by 2031, growing at a CAGR of 17.8% from 2022 to 2031.

Rise in need for voice-based devices drives the speech-to-text API market growth. Several new advanced devices are being introduced with voice-controlled features, which include voice processing features, such as content transcription, conference call analysis, enabling users to access educational, entertainment and other content through their smart devices. In addition, rise in need for voice-based devices for better and faster experience is also boosting market growth. Thus, these factors drive the growth of the speech-to-text API market size.

However, transcribing audio from multichannel may hinder the adoption and multilingual support for captioning and subtitling hampering the growth of the speech-to-text API market size. On the contrary, innovation in speech-to-text solutions for disabled students will provide major lucrative opportunities for growth of the market.

Speech-to-Text API Market

The speech-to-text application programming interface (API) is a programming interface that enables the utilization of speech synthesis and recognition in a variety of devices and applications. Speech-to-text API is a multidisciplinary subject of computational linguistics that explores methods that allow computers to translate and recognize audible language into text. This is also called as Automatic Speech Recognition (ASR) or Speech-to-Text. It encompasses electrical engineering, computer science, and linguistics research and knowledge. Moreover, it provides hints to boost the transcription accuracy of rare and domain-specific words or phrases. Use classes to automatically convert spoken numbers into addresses, years and currencies.

Top Impacting Factors

Rising Need for Voice-based Devices

With the growing technological adoption and massive proliferation of internet-based content, the need for smart devices, such as smart speakers and mobile phones, has been increasing from the last decade, which resulted in the increased need for making online video content accessible for every individual. Several new advanced devices are being introduced with voice-controlled features, which include voice processing features, such as content transcription, conference call analysis, enabling users to access educational, entertainment and other content through their smart devices. Hence, speech-to-text applications have increased due to the increased need for understanding customer preferences.

Moreover, the demand for smart homes and smart appliances is increasing owing to various factors, including growing internet penetration, advancements in technology, and increasing awareness about automation. The COVID-19 pandemic has also resulted in the increasing use of smart devices and appliances in almost every aspect of daily life people have been forced to work from home, which is increasing demand for speech-to-text API in the market.

Rise in Demand of AI in Speech-to-text Technology

Advances in speech recognition technology have enabled businesses to develop voice-enabled interfaces that match consumer expectations thanks to significant advancements in natural language processing (NLP) and speech quality. Moreover, continuous enhancements in Al, cloud computing, and information technology have empowered innovations such as voice-to-text progress at a remarkable pace, which contribute to augment the speech-to-text API market growth.

In addition, advanced technologies such artificial intelligence and machine learning enable conversational devices to accurately perceive speech, which improves the system's capacity for self-learning. Furthermore, Al-based speech and voice recognition systems will automatically capture the complete agent-customer interaction to provide hidden feedback and opportunities. Therefore, this is a major propelling factor for the speech-to-text API market.   

Transcribing Audio from Multichannel

Transcribing audio from multiple channels is a major restraining factor for this technology because defining multiple entities becomes difficult and can cause inaccurate transcriptions or captioning Moreover, background noise low-quality microphones, reverb and echo, and accent variations may hamper the transcription accuracy Speech-to-text APIs should be trained properly for multi-channel speech recognition through numerous types of data sets; however, it becomes difficult for enterprises to gather a variety of data sets for building their approach and solution that accurately converts speech-to-text for multiple channels. Therefore, this is a major factor hampering the growth of speech-to-text API industry.

Multilingual Support for Captioning and Subtitling

The language differentiation across the globe is the major concern for content creators to create transcripts and subtitles accurately for every language speech-to-text API solutions have been difficult to implement in countries that have several regional and local languages. As consumers and enterprises located across different parts of a country speak a variety of local languages, approaching them with a generic solution will not add any value to their business and would not lead to the successful penetration of speech-to-text API solutions. Moreover, solutions must be different in terms of functionality and platform from mainstream mobility solutions.

In addition, several speech-to-text API solution providers are making efforts to ensure users who speaks a single language and cannot speak other languages apart from their local dialect would get an opportunity to access speech-to-text features on their smartphones as well huge benefits can be achieved by designing speech-to-text API solutions for micro-linguistics and local languages.

Innovation in Speech-to-text Solutions for Disabled Students

With the help of the speech-to-text API technology, any video or audio-based content can be converted by a computer into text, which helps struggling listeners or hard of hearing students read correctly and do their work without taking help from others. For instance, speech-to-text software can enable a deaf- mute student to communicate with his/her teachers and classmates. Hence, this system works as assistive technology, helping disabled people benefit from the ICT.

Moreover, the individuals with Disabilities Education Act (IDEA) provides interactive software for disabled students. These students are unable to hear properly in the classroom. To overcome this, Gaylen Kapperman and Jodi Sticken of Northern Illinois University developed an interactive software tutorial that helps these students study the Nemeth code (a Braille code for mathematics) with the help of speech-to-text technology. The software is installed in Braille Lite-a small, portable Braille Notemaker that is equipped with synthetic speech software and a refreshable Braille display.
