Vispero

Blind and low-vision people run JAWS, ZoomText, and Fusion to read screens, magnify text, and operate applications that sighted users navigate by sight alone, paying for access to a digital environment that builders constructed without them.

What it is

WebAIM's 2024 Screen Reader User Survey found that 40.5% of respondents used JAWS as their primary desktop screen reader, and 60.5% listed it among screen readers they commonly used.¹ JAWS (Job Access With Speech) converts on-screen text, interface elements, and document structures into synthesized speech or refreshable Braille output, letting blind users operate Windows applications, browse the web, and read documents through auditory and tactile channels. ZoomText enlarges and re-renders on-screen content for people with low vision, adjusting magnification, color contrast, and cursor tracking so that partially sighted users can read interfaces that ship with fixed font sizes and insufficient contrast. Fusion combines both programs into a single installation, and Vispero markets it toward people with progressive vision loss who move between magnification and full screen reading as their sight changes.

Vispero, headquartered in Clearwater, Florida, assembled these products through a series of acquisitions. Vector Capital, a private equity firm, simultaneously acquired Freedom Scientific and Optelec in late 2015 and merged them under the Vispero name.² Freedom Scientific had itself formed in 2000 when Henter-Joyce, the original maker of JAWS, merged with Blazie Engineering and Arkenstone.³ Vispero added Enhanced Vision in 2018 and had acquired The Paciello Group (now TPGi), an accessibility consulting firm, in 2017.² The resulting company sells assistive technology software, electronic video magnifiers, Braille displays, and accessibility consulting and testing services across more than 70 countries.

JAWS Professional carries a perpetual license price of roughly $1,100 for a single user. Freedom Scientific introduced annual Home licenses in 2018 at $90 per year for JAWS and $80 per year for ZoomText, as Bill Holton reported in AccessWorld, targeting users who found upgrade costs prohibitive or lacked agency sponsorship.⁴ State vocational rehabilitation agencies, the Veterans Administration, and educational institutions fund many licenses, treating the purchase as an employment investment. Employers with multi-user enterprise agreements can extend Home Edition licenses to employees or students for $125.⁴ Freedom Scientific's trial version restricts use explicitly, with license terms that prohibit using the 40-minute demo for "development and testing of JAWS scripts, applications, HTML coding, or other Web Based code," as Jared Smith documented in a 2008 WebAIM analysis.⁵ Eric Eggert noted in 2022 that developers who cannot afford or access JAWS for testing default to NVDA or skip screen reader testing entirely, and that Freedom Scientific's restriction on evaluation use discourages the very testing that would improve JAWS users' experience.⁶ Vispero later released JAWS Inspect, a separate product that renders JAWS speech output as text for sighted testers, though it requires its own license and does not replace hands-on screen reader testing by blind users.

NVDA, a free and open-source screen reader that Michael Curran began writing in 2006 because he found commercial screen readers unaffordable, now serves 37.7% of primary desktop screen reader users globally and 65.6% when respondents name all screen readers they commonly use.^{1 7} Curran and James Teh, who met as blind teenagers at a music camp in New South Wales, founded NV Access in 2007 to manage continued development.⁸ NVDA's zero-cost availability removed the financial barrier to developer testing and gave blind users in countries without vocational rehabilitation funding their first access to a full-featured Windows screen reader.

Why it matters

Scribes, typographers, and eventually software engineers encoded information in visual form and left blind readers to find their own path to the content. Ray Kurzweil's 1976 reading machine and IBM's 1986 Screen Reader, which Jim Thatcher developed at IBM Research, gave blind users their first computational access to printed and on-screen text.⁹ Ted Henter, a championship motorcycle racer who lost his sight in a 1978 automobile collision in England, enrolled in computer programming at the University of South Florida and spent years working in the field before teaming up with investor Bill Joyce to found Henter-Joyce in St. Petersburg, Florida in 1987.¹⁰ Henter released the first version of JAWS for DOS in 1989, naming it after a joke with a friend about a competitor called Flipper, then retrofitting the acronym "Job Access With Speech."¹⁰ JAWS distinguished itself through user-customizable scripting that let blind users adapt the reader to specific applications, and its Windows version, released in January 1995, arrived just as employers began requiring graphical computing skills. Richard Chandler, formerly CEO of Sunrise Medical, orchestrated the 2000 merger of Henter-Joyce, Blazie Engineering, and Arkenstone into Freedom Scientific, seeing higher margins in assistive technology than in his prior medical device business.¹¹ Paul Schroeder reported in AccessWorld that competitors worried the consolidation would allow Freedom Scientific to dominate the market, and Jim Halliday of HumanWare criticized Chandler's decision to terminate their JAWS dealership arrangement.¹¹ Vector Capital's 2015 acquisition of Freedom Scientific and Optelec repeated the pattern at larger scale, consolidating the three largest Western assistive technology hardware and software brands under one private equity owner.² That consolidation gave Vispero dominant market position, but it also concentrated pricing power over a product that blind workers need in order to hold jobs in a digital economy. NVDA's emergence in 2006 as an open-source alternative created the first credible check on that concentration. Michael Curran and James Teh built a screen reader funded by donations and grants rather than license fees, and by 2024 NVDA had reached near-parity with JAWS in primary usage and surpassed it in common usage.^{1 7} Of WebAIM's 2024 survey respondents, 78.1% viewed free or low-cost screen readers as viable alternatives to commercial products, up from 48% in 2009.¹

Computer science programs rarely teach semantic HTML, ARIA landmarks, or accessible design as core competencies, and the professional norms they produce reproduce the exclusion that screen readers then must bridge. WebAIM's 2026 analysis of the top one million home pages found that 95.9% had detectable WCAG 2 failures, averaging 56.1 errors per page.¹² Developers ship unlabeled buttons, inaccessible forms, and images without alt text not because individual engineers intend to exclude blind users but because the training pipeline, hiring criteria, and sprint structures that govern their work treat accessibility as an optional enhancement rather than a requirement. Freedom Scientific's own licensing terms reinforce this norm by prohibiting developers from using the JAWS trial version for testing, a restriction that Jared Smith at WebAIM called counterproductive because it prices out the very developers whose work determines whether JAWS users encounter accessible interfaces.⁵ Reuschel, McDonnall, and Burton tested 30 Fortune 500 company job application websites with screen reader users in 2023 and found that 76.7% had critical issues preventing at least one tester from completing an application independently, with only 55.6% of 90 total attempts succeeding without sighted assistance.¹³ Aaron Page, Director of Accessibility at Allyant and a blind user of JAWS, described abandoning websites that lack useful headings or landmark regions, and he rejected accessibility overlay tools that force him to disclose his disability before a site will render properly.¹⁴ The 71.6% of WebAIM respondents who reported using more than one screen reader reveal the scale of navigator-side compensation labor involved. Users maintain fluency in multiple tools because no single screen reader handles every inaccessible site, and they carry the cost of learning, configuring, and switching between them.¹

Vispero charges blind users for access to a digital environment that builder-side neglect has already made hostile to them. A blind worker whose employer does not provide JAWS needs roughly $1,100 for a perpetual Professional license or $90 per year for a Home license, a recurring expense that sighted workers never face. State vocational rehabilitation agencies fund many of these purchases, but they do so through an employment-contingent model that ties assistive technology access to labor-market participation. Retired users, people between jobs, and disabled people whom the labor market has excluded receive less support. Scope's 2025 Disability Price Tag report found that disabled households in the United Kingdom need an extra £1,095 per month on average to reach the same standard of living as non-disabled households, with assistive devices, specialist equipment, and adaptive technology contributing to that gap.¹⁵ Vispero's 2018 subscription pricing reduced the entry point, but the adaptation tax remains. Blind users pay for the tools that let them participate in systems that sighted users access at no additional cost, and those tools function well only when builders have done the development work of coding semantic HTML and following WCAG guidelines. When builders skip that work, the screen reader still runs, but it encounters unlabeled elements, keyboard traps, and visual layouts that resist linear parsing. The user absorbs the cost of the tool and the labor of working around the tool's limits.

Marta Russell argued in Beyond Ramps and subsequent essays that capitalism treats disabled people's bodies as a resource from which industries extract value, turning impairment into a market opportunity for medical, rehabilitation, and device companies while keeping disabled people themselves in positions of economic dependency.¹⁶ Vispero generates revenue from products that exist because builders failed to make digital environments usable without them. If every website met WCAG standards, if every application shipped with semantic structure and keyboard operability, the market for screen readers would not disappear, because blind users still need non-visual interfaces, but the compensatory function that drives much of the market's volume would shrink. Russell did not indict individual AT companies for serving a real need but named the arrangement that produces the need and asked who profits from its perpetuation. The blind and low-vision community has organized around exactly this distinction. The National Federation of the Blind has advocated for accessible technology standards alongside AT funding, recognizing that assistive technology alone cannot substitute for builder-side care. NVDA's open-source model, funded by community donations and grants from organizations including Mozilla and Microsoft, represents one community-generated response to the commodification of access. NVDA does not eliminate the adaptation tax, because users still carry the labor of navigating inaccessible environments, but NV Access removes the license fee from the equation for users whom vocational rehabilitation and employer funding do not reach.⁷

Blind and low-vision people face 1.6 to 2.8 times the risk of depression compared to sighted populations, with 10.7% to 45.2% reporting moderate-to-severe depressive symptoms, as Demmin and Silverstein documented in their 2020 review in Clinical Ophthalmology.¹⁷ Builders who ship inaccessible digital environments contribute to that differential risk by restricting autonomy, forcing dependency, and narrowing social participation. When a blind user cannot complete a healthcare appointment form, book travel, or access a child's school portal without asking a sighted person for help, the resulting dependency compounds the exclusion that the inaccessible interface created. McDonnall, Steverson, Sessler-Trinkowsky, and Sergi surveyed 314 employed blind and low-vision workers and found that 59.1% encountered difficulties accessing software, websites, databases, or digital documents at work, with inaccessible documents, presentation software, and employer databases ranking among the most common barriers.¹⁸ Michael Taylor, a screen reader user writing for UsableNet in 2025, described a travel booking experience so inaccessible that he had to abandon the task and ask a sighted person to complete it, and he estimated that half the apps on his phone did not work for him.¹⁹ McDonnall and Sui's 2019 analysis found that only 44% of working-age Americans with visual impairments held employment, compared to 78.6% of people without disabilities, and that 61% of working-age adults with vision loss were entirely outside the civilian labor force.²⁰ In 2024, the EEOC settled a case against The Results Companies for $250,000 after the firm hired a blind customer service representative in Texas, failed to install the JAWS screen reader she had requested, refused to contact Freedom Scientific for technical support, and then terminated her.²¹ The case documented how an employer's failure to complete a single builder-side development task, installing and configuring assistive technology, converted a qualified worker into an unemployed one. Inaccessible digital platforms contribute to the employment gap directly, because jobs that require web-based applications, cloud-based tools, and browser-accessed platforms become inaccessible when those platforms fail basic screen reader compatibility, and the blind worker who cannot complete a job application, navigate a company intranet, or use a project management tool faces exclusion that no amount of personal assistive technology can overcome.

Vispero's consolidation made possible product integration, such as Fusion and cross-platform Braille support, that smaller firms could not sustain independently, and NVDA's parallel rise gave blind users a zero-cost alternative that reached populations whom commercial licensing and vocational rehabilitation never served. Together, the two screen readers extended non-visual access to Windows computing further than any prior decade, but both face a deeper constraint upstream, because WebAIM's million-page studies show that the web grew less accessible between 2025 and 2026, not more, with detectable errors per page increasing 10.1%.¹² NVDA depends on community funding and volunteer labor that remain structurally fragile, and Vispero's private equity ownership concentrates pricing power in an arrangement where blind users already carry the adaptation tax. As long as builders treat accessible development as optional, screen readers will function partly as tools of participation and partly as instruments of compensation, and blind users will carry the cost and labor of both.

A Look at New Features in the JAWS 2023 Release (November 2022)
-- Jamie Pauls, AccessWorld (American Foundation for the Blind)

• Pauls reviewed JAWS 2023's Smart Glance feature, which detects visually emphasized content that developers did not mark with semantic HTML elements. The feature addresses a persistent gap in builder-side development practice, where developers use visual styling (color, font weight) to convey meaning without providing equivalent semantic structure for screen readers. Pauls noted that the feature sometimes flags less relevant items like copyright dates, illustrating the difficulty of compensating computationally for missing content structure.²²

A New Way to Obtain JAWS and ZoomText (December 2018)
-- Bill Holton, AccessWorld (American Foundation for the Blind)

• Holton reported on Freedom Scientific's introduction of annual subscription licenses for JAWS ($90/year) and ZoomText ($80/year), a shift from the perpetual license model that had priced many individual users out of the product. The subscription targeted users with outdated software versions who found upgrade costs prohibitive or lacked vocational rehabilitation sponsorship, reducing the financial barrier to assistive technology while converting the cost from a one-time purchase to a recurring obligation.⁴

Digital Accessibility in 2025: A Screen Reader User's Honest Take (July 2025)
-- Michael Taylor, UsableNet

• Taylor, a screen reader user, described travel booking websites so inaccessible he had to ask a sighted person for help, and he estimated that half the apps on his phone did not work for him. He noted genuine improvement in e-commerce and online banking accessibility while identifying healthcare management and mobile apps as persistent failure points, a pattern consistent with uneven builder-side iteration across industries.¹⁹

Blind worker to receive $250,000 for call center's failure to accommodate (October 2024)
-- Caroline Colvin, HR Dive

• The EEOC settled a disability discrimination case against The Results Companies after the firm hired a blind customer service representative, asked her to step down when she requested JAWS, failed to install the software upon her return, refused to contact Freedom Scientific for technical support, and then fired her. The case documented how an employer's refusal to complete a single builder-side development step, installing and configuring assistive technology, converted a qualified worker into an unemployed one.²¹

• Aaron Page, Director of Accessibility at Allyant and a blind JAWS user, described abandoning websites that lack heading structure and rejecting accessibility overlay tools that require him to disclose his disability before a site renders properly, calling instead for sites that "should just work for me without doing any of that."¹⁴
• WebAIM's 2024 survey found that 85.9% of screen reader users said more accessible websites would improve their experience more than better assistive technology, placing the burden of change on builders rather than on navigator-side tools.¹
• During the COVID-19 pandemic in March 2020, Freedom Scientific made JAWS, ZoomText, and Fusion available free of charge to anyone in the United States and Canada with a personal email address, initially through June 2020 and later extended through August 2020, acknowledging that the shift to remote work and online services had made screen reader access an immediate necessity for blind and low-vision people who lacked current licenses.²³

What care sounds like (builder-side interventions)

Care at the development and design stages involves building digital environments that screen readers can parse without requiring users to compensate for missing structure:

• "We tested every form field with JAWS and NVDA before merging the pull request."
• "We labeled all interactive elements so screen readers announce their purpose without users having to guess."
• "We structured the page with heading levels and landmark regions so keyboard and screen reader users can jump to content the same way sighted users scan visually."
• "We included blind testers in our usability study and changed the checkout flow based on what they could not complete."

What neglect sounds like (builder-side interventions)

Neglect at the development and requirement-setting stages involves building for sighted users and treating screen reader compatibility as someone else's problem:

• "It looks fine on screen, so it should be fine."
• "Screen reader support is not part of the MVP."
• "We will add accessibility in a later sprint."
• "Only one user reported that issue, so it is not a priority."
• "The screen reader cannot read it? Maybe they need a newer version."

What compensation sounds like (navigator-side compensations)

Compensation describes the labor blind and low-vision people carry when builders ship inaccessible digital environments:

• "I spent twenty minutes tabbing through unlabeled buttons trying to find the submit control on a form a sighted person fills out in thirty seconds."
• "I keep JAWS, NVDA, and VoiceOver installed because no single screen reader handles every broken site, and I switch between them depending on which one can parse the layout."
• "I had to call my daughter to read me the healthcare portal because the form fields were images that my screen reader could not detect."
• "The travel site was so broken I gave up and asked someone sighted to book the flight for me."
• "I pay $90 a year for software that lets me use websites other people access for free, and half those sites still do not work."

---

All observations occur within the context of the global assistive technology market for blind and low-vision users, centered on U.S. and European markets where vocational rehabilitation funding, employer licensing, and individual subscription purchases determine who can afford screen reader access to a digital environment that builders have not made independently usable.
