The global speech-to-text API market size was valued at USD 1,321.5 million in 2019 and is projected to reach USD 3,036.5 million by 2027, exhibiting a CAGR of 11.0% during the forecast period.

Increasing migration towards voice-enabled applications is leveraging machine learning (ML), augmented reality (AR), and natural language processing (NLP) to automate the conversation. The growing popularity of smart mobile phones and smart speakers are leading to the adoption of voice enabled systems. Moreover, real-time support services and popularity of transcription encourage the industry giants to develop speech-to-text API solutions. For instance, in 2017, Fujitsu Social Science Laboratory Limited and Fujitsu Limited developed FUJITSU Software Live Talk, which is a communication tool for the hearing-impaired. The company added multilingual translation functionality to the system to support real-time communication and to immediately display translations as text on screen.

Considering the current COVID-19 pandemic situation, large enterprises and small and medium enterprises (SMEs) are expected to reduce their research & development spending on speech-to-text software and solutions which might disrupt the speech-to-text developments. However, the demand for such solutions is anticipated to see substantial increase due to social distancing and stay-at-home initiatives taken by the world. The adoption of these solutions is expected to exhibit high adoption in industries such as healthcare, e-learning, and media & entertainment to optimize the overall execution of operations.

The speech-to-text API market is further projected to showcase considerable growth due to increasing cancellation of conferences and events by technology giants. It has led to conducting digital or virtual conferences. As speech-to-text solutions offer faster transcription, low costs, and high accuracy, it is expected that multiple enterprises might adopt these solutions to speed-up the processes such as news and speeches given by political leaders and conferences.

Adoption of IP-based Interactive Voice Response (IVR) in Contact Centers Trending in the Market

Contact centers have developed from simplistic stand-alone activities distributed over a single platform to multi-site, multi-functional customer experience management systems. By using sophisticated speech-to-text solutions, it is possible to create a seamless and flexible framework to provide outstanding customer support. Businesses can also create an organized means of gathering consumer details and motivating call center agents. In April 2019, the GL Communications, Inc. developed a speech-to-text conversion application which is used for testing Voice Mail (VM) systems and Interactive Voice Response (IVR), as well as for voice transmission over any network and confirming voice prompts.

Speech-to-text technology helps contact centers to better grasp the voice of customers by doing in-depth data mining on customer communications. In addition to this, these solutions provide contact centers with an easy way to gauge their consumers and gain a deeper understanding of customer needs.


Smart Speakers and Intelligent Voice Assistants to Drive the Revenues through Speech Recognition

In the last few years, the use of smart speakers and voice assistants, such as Alexa, Siri, Cortana, and Google Assistant has increased. As these devices are integrated into more households, voice-enabled apps are likely to radically transform how users participate with technology. Smart speakers have grown in prominence, with predictions that the number of households using them would rise dramatically in the coming year. Without a question, this evolution of voice enabled smart speakers provides fascinating possibilities, making it easy for users to navigate the internet environment or operate certain tools.

In addition to broader language assistance, smart speakers and voice assistants boost the quality of speech recognition, which can be extended and amortized through a wide variety of platforms. Moreover, increased availability of smart speakers which consume less power as compared to the previous ones has made an additional contribution to the growth of the market. 

Although, recordings obtained by voice assistants provide companies with fresh proof of data that can theoretically be utilized to profile customers in other areas – such as emotion analysis or also facets of mental well-being. Popularity of such intelligent voice assistants is likely to drive the growth of this market.

Artificial Intelligence (AI) Incorporated with Speech Technology Promises to Increase Profits and Transform Businesses

With substantial improvements in natural language processing (NLP) and speech quality, advances in speech recognition technologies have led companies to create voice-enabled interfaces that meet the consumer standards. Tandem enhancements in AI, 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.

With advanced technologies such as artificial intelligence and machine learning, conversational devices are able to properly understand the speech which enhances self-learning abilities of the system. AI based speech-to-text conversion models are able to enhance accuracy and adapt automatically to the changes in languages. Speech-to-text with AI has become an ordinary service with the increasing application of these models. Further, AI-based speech and voice recognition systems will automatically capture the complete agent-customer interaction to provide hidden feedback and opportunities.


Privacy Issues to Impede Adoption of Voice-enabled Applications

Privacy issues regarding voice-enabled devices are becoming one of the major restraining factors for the market growth. Many subsequent cases about privacy issues from voice-controlled virtual assistants confine the adoption of voice-enabled devices. For instance, Google LLC was restricted by Germany’s data protection commissioner to listening Europe’s voice recordings in August 2019, as the privacy issue arrived by Google’s AI-based speech recognition technology.
