Quantitative Breakdown of Voice Assistants’ Technology ROI for Modern Enterprises

A 2019 survey by PWC showed that over 90% of consumers aged between 18-64 years had sought knowledge about voice technology, while over 70% had used it at least once. This massive wave of consumers adopting voice technology for home improvement and ease-of-usage has ushered in a new age for voice assistance. The new consumer trend has also had a positive impact on the business world. The voice assistant market that was worth USD 11 billion in 2019 is now expected to grow by 17% by 2025.

As a result, every year more companies are exploring AI-based voice technologies and finding ways to implement voice assistants both internally and externally for cost savings, automation, business intelligence (BI), and better customer experience.

Another survey by Juniper showed that there were at least 3.25 billion enterprise voice assistants in operation, and the number could reach over 8 billion by 2023. Continuous breakthroughs in AI voice technologies also mean that more businesses find voice assistants increasingly beneficial in business settings. Voice recognition has become an integral part of service delivery as more connected devices enter the market with artificial intelligence and machine learning expanding globally.

Today, enterprise-ready virtual assistants are replacing previous-gen speech recognition systems that failed to imitate the natural human voice experience. This article breaks down the ROI of voice technologies for modern enterprises and offers a quantitative analysis of the overall business value of voice assistant technology.

Integration of Voice-Enabled Technologies

One of the leading use-cases of AI-enabled voice bots is digital assistance. These voice assistants are already very popular on different platforms including smartphones and wearable devices, and especially, smart speakers.

Smart speakers are the most widespread voice assistance devices after smartphones in 2020. According to voice assistant statistics, at least 127 million smart speakers were shipped globally in 2020, with China taking the lion’s share. There were over 3 billion AI voice assistants in use in 2019, and the number is expected to grow to over 6 billion by the end of 2023. The voice assistants are mainly used to accept commands or respond to customer queries.

Speech-to-text automated transcription has become an integral part of businesses in the market research and e-learning industry and advanced voice technology recognition made possible by Conversational AI has significantly improved the quality of the transcriptions.

Furthermore, most decision-makers and senior employees have adopted some level of voice-activated technologies personally, but fewer than 31% use them at the business level. It’s not yet clear why a divide exists in perception about deploying virtual assistants, artificial technology in the workplace versus in the home. This forked thinking maybe because over 75% of businesses identify virtual assistant artificial intelligence as a significant initiative but are slow to integrate voice assistant technology into their business models. The fence-sitters often cite the initial investment and the time it takes to train staff for implementing the technology as a constraint. Since most people are already using them at home, training would require shorter periods in case of adoption.

Voice: Challenges amid Opportunity

Ai-enabled virtual assistants have been used for a while now to perform a wide variety of tasks, from answering general questions to finding the right restaurants for a particular occasion. eMarketer recently recorded at least 112 million people using voice assistants in the U.S. monthly, and the figure has risen to over 132 million in 2021.

The increased interest in voice assistant technology means a more significant opportunity for marketers to engage, reach and better understand potential customers. According to Voiceboat.ai, 85 percent more people use smart speakers or over 87.7 million more users, offering marketers a greater chance to reach their target audience.

Virtual assistant artificial intelligence enables marketers to have more personalized conversations, thus allowing the users to share exactly what they are looking for so marketers can give customized answers, thus enhancing personalized experience. Marketers can also make multiple sales since they can access entire households using one voice assistant, sell more, and collect more insights through one campaign.

There remain a few concerns with data security concerns leading the pack with so many benefits of leveraging voice assistants. Some consumers are still wary of what the companies behind the Apps do with their personal data. Voice assistants don’t yet provide as enriching interaction as other channels, which could diminish engagement quality compared to what is available elsewhere. It’s still a bit costly to develop a voice app. In contrast, internal building capacity and developing Voice Engine Optimization (VOE) so you can fully use voice assistants require an investment in time.

Additionally, not all voice assistants are built the same. Some of the voice assistants built today face accuracy limitations brought about by different dialects and accents, timing, word error rate (WER), and difficulty in formatting, and background noise. And while these barriers to fully embracing virtual enterprise assistants do exist, several organizations in the U.S. continue to develop AI voice assistant technologies.

Savings and Benefits of Voice Assistant Adoption

The findings of the Opus Research survey indicate that voice technology is making a significant impact across various sectors, leading many executives to recognize its potential for transforming businesses. In this discussion, they explore the specific areas and scenarios where voice technology can provide value, ranging from improving productivity to enhancing customer experiences .

An effective approach to assessing the value of a technology for an organization is to consider the implications for industry peers if they choose not to adopt it. This is precisely the question that Opus Research addressed in their survey. The majority of respondents (59%) indicated that businesses that neglect to implement voice technology can expect a decline in customer satisfaction scores, leading to a reduced likelihood of customers enthusiastically recommending their products and services. Additionally, 63% of respondents expressed that Net Promoter Scores (NPS) would decrease without the inclusion of voice capabilities.

Apart from assessing the impact, respondents also had the opportunity to share their evaluations of the savings and benefits they have experienced through the adoption of voice technology. Interestingly, this year’s primary observed impact appears to be a shift towards cost savings, in contrast to the previous year where productivity gains took precedence. According to 51% of respondents, leveraging voice technology has resulted in cost savings ranging from 26% to 75%. However, productivity gains remain significant as well, with 49% of respondents reporting an increase in productivity ranging from 26% to 75% directly attributable to the implementation of voice technology.

The survey findings also indicate a continued investment in voice technology. A significant majority of respondents (81%) expressed their intention to either “Increase” or “Increase Significantly” their budgets for speech technology. This underscores the recognized value and essential role of speech technology in both ongoing digital transformation initiatives and day-to-day operations of companies.
