What Does G2’s AI Market Report Reveal About AI Voice Assistant Adoption in 2026?
Key Insights
- Based on 1,419 verified reviews from G2’s 2025 State of AI in AI Voice Assistants Survey, 76% of AI voice assistant users acknowledge significant or transformational operational ROI. However, measuring this ROI ranks as the third biggest challenge. Organizations recognize the value provided but struggle to internally measure and verify it. The benefits are undeniable, yet proving them remains difficult.
- Adoption of voice AI continues to grow steadily across all sectors. With 88% of platforms reporting rapid adoption increases in the last 12 months and 65% describing the current phase as “rapid adoption across industries,” the focus has shifted from whether to invest in voice AI to when to do so.
AI voice assistants have moved beyond experimentation, with over half of users having fully operational systems and rising popularity across multiple industries and segments.
G2 analyzed verified reviews and surveyed 17 prominent AI vendors to assess AI voice assistants’ real-world performance. The findings show soaring adoption, and while all respondents plan to greatly increase their investment, demonstrating clear value and ROI is lagging behind.

Key Findings
- According to G2’s 2025 State of AI in AI Voice Assistants Survey, and based on 1,419 verified reviews, 76% of AI voice assistant users report significant or transformational operational ROI. Yet, measuring that ROI simultaneously ranks as the #3 challenge. Organizations believe in the value being delivered, but cannot measure and prove it internally. There’s no doubt the benefits are real, but the proof remains a challenge.
- Voice AI adoption is steadily growing across all segments. With 88% of platforms reporting rapidly increased adoption over the past 12 months and 65% describing the current stage as “rapid adoption across industries,” it’s clear that the question isn’t whether to invest in voice AI, but when.
AI voice assistants are no longer an experiment; the software is fully operational for over half of users, and popularity is accelerating across all industries and segments.
G2 analyzed verified reviews and gathered responses from 17 leading AI vendors to understand how AI voice assistants are performing in real-world environments. The data reveal that software adoption is soaring, and even though 100% of survey respondents expect to significantly increase their investment, the ability to demonstrate its value and ROI hasn’t kept pace.

What is the state of AI in AI voice assistants in 2026?
Our survey data shows that 65% of platform users describe the current industry stage as “rapid adoption across industries,” and 88% report that adoption rapidly increased over the past 12 months alone. This signals that this category is already quite mainstream, despite its relatively young age.
What’s interesting about this fast adoption is that companies with fewer than 10 employees (SMB) represent the single largest reviewer segment, while enterprise organizations account for just 59 reviews combined. Voice AI assistants didn’t get adopted because large companies were early trend-setters and spreading the word. It gained popularity because smaller organizations that probably didn’t have to cut through the purchasing red tape with a procurement team, multiple approvals, etc., were advocates of the software and were able to easily buy and implement it.
When a category grows this fast from the “bottom up”, I believe it signals one of two things: either the technology is solving a legitimate problem at a low barrier to entry, or expectations are outpacing reality. In the case of AI voice assistants, the data points to the former. The category averages a 9.26 out of 10 user recommendation score from 1,419 reviews, an unusually high score for a market still rapidly growing. Our data shows that the software is definitely meeting users’ expectations, and now organizations need to incorporate and scale to meet their customers’ needs to stay competitive.
What are verified buyers saying about AI in AI voice assistants?
User sentiment from the market is nearly unanimous. Across 1,419 verified G2 reviews, 93.1% of buyers express positive sentiment by rating their AI voice assistant experience 4 stars or above (out of 5). Just 4.9% are neutral, and only 2.0% are negative. For a category still growing and experiencing real infrastructure challenges, that level of satisfaction is impressive.
On the positive side, buyers consistently highlight ease of setup, the quality of voice agents, and time savings in customer support. On the not-so-positive side, the pain points are pricing at scale and gaps in features cited most frequently. However, reviewers use the words “would” and “could” a lot, which feels more like suggestions, rather than outright criticism or dissatisfaction. They’re buyers who see the potential and want more of it.
What are buyers prioritizing in AI voice assistants in 2026?
Structured input from our survey and user reviews helps us understand what buyers are prioritizing, and why. A couple of common themes, as demonstrated by actual user quotes below, show where they are finding ROI in simple, day-to-day operations, such as tickets and queues, not through large, complicated projects. As well as how they are unlocking ROI with quick onboarding and deployment, and a low barrier to entry. But again, the challenge is having the right tools to prove the ROI is there.
Theme 1: Delivering ROI through self-service. A software engineer from a mid-market-sized company says of Kore.AI, “The biggest benefit has been the self-service aspect — customers get instant answers to things like order tracking without waiting in a queue. Smart, no-code AI that deflects tickets and delivers clear ROI.”
Theme 2: Quick deployment/onboarding. “For what it costs and how quickly you can get started, it’s been one of the easier wins for us — and we did it all without adding headcount,” says a software developer for a small business about Ringg AI.
What does G2’s AI market report for AI voice assistants mean for buyers?
The data from our vendor survey shows us that the market has already made up its mind. AI voice assistants are no longer being evaluated as a “nice to have” software; companies are actively buying, using, and scaling them. The question for most organizations in 2026 isn’t whether voice AI works. It’s whether they’re moving fast enough to keep up with the companies that have already figured this out.
For buyers, two things stand out clearly. First, the ROI is real, but it’s being seen before it’s being measured. Organizations are experiencing operational gains, such as faster response times, reduced support costs, and self-service that actually works, but most still lack the tools to measure what they know is happening. For buyers who have already deployed voice AI and haven’t invested in a way to measure this, that’s the gap to close next. The value is there, but they need to clearly see it to prove it, defend it, and expand on it.
Second, the barrier to entry seems to be very low, but the barrier to scale is higher. The data shows that buyers are getting the software up and running quickly, often without adding headcount. The initial deployment isn’t the issue; it’s integrating voice AI into existing infrastructure, aligning it to disparate data, and getting organizational buy-in (proving ROI) to move from the pilot stage to full deployment and usage.
For buyers evaluating AI voice assistants today, the market data has already validated the category and its ROI, and that satisfaction is high across every segment. The only risk now for buyers isn’t whether to adopt, but to wait any longer.
