The Open Voice Network Interoperability and TrustMark projects are incubation projects within the non-profit, vendor-neutral Linux Foundation AI & Data Foundation.

The mission of LF AI & Data is to build and support an open artificial intelligence (AI) and data community, and drive open source innovation in the AI and data domains by enabling collaboration and the creation of new opportunities for all the members of the community. Learn more at

Technologists, industry practitioners, academic researchers, and ethicists come together from around the world to pursue the aims of the Open Voice Network: to build the open, standards-based, interoperable, and trustworthy future of voice / Conversational AI.

What this means to you: a level playing field, with unfettered access to constituents and new markets. Efficiency in development and delivery: build and maintain once, with use everywhere. Accelerated innovation: standard building blocks allow investment in differentiation. A confidence in the data behavior of others.

Open Voice Network projects are guided by four ideals. We seek a world in which conversational AI technology

is worthy of user trust

enables user, ecosystem, and architectural choice

is inclusive and accessible

is open in software and hardware, with standards serving as a foundation for commercial differentiation.


The Open Voice Network Interoperability and TrustMark Initiative projects joined the prestigious Linux Foundation AI & Data Foundation with incubation status on November 1, 2023.

Previously, the projects were part of the Open Voice Network, a much smaller, independent Linux Foundation community, which grew from 2016-2018 collaborative research by the Auto-ID Center of the Massachusetts Institute of Technology (MIT), Capgemini Consulting, and the Intel Corporation, and was founded in June 2020.

As part of the LF AI & Data Foundation, the Open Voice Network Interoperability and TrustMark Initiative projects will enjoy collaboration opportunities with numerous existing and in-development LF AI & Data projects in areas of natural language processing, data privacy and security, trustworthy AI, and the new LF AI & Data Generative AI Commons. The Open Voice Network projects also have access to the shared legal, operational, and marketing services of the LF AI & Data Foundation.

About the Linux Foundation
The Linux Foundation is dedicated to building sustainable ecosystems around open source projects to accelerate technology development and industry adoption.

Founded in 2000, the Linux Foundation provides unparalleled support for open source communities through financial and intellectual resources, infrastructure, services, events, and training. Working together, the Linux Foundation and its projects form the most ambitious and successful investment in the creation of shared technology.

Please visit the Linux Foundation website for more information.

The LF AI & Data Foundation supports and sustains open source projects within artificial intelligence (AI) and the data space. You can think of us as a greenhouse growing and sustaining open source AI and data projects from seed to fruition. We provide support to projects for open development among a diverse and thriving community, in addition to a number of enabling services that include membership and funding management, ecosystem development, legal support, PR/marketing/communication, events support, trademark management, export control filings, and compliance scans.

What do we value

A Shared Vision & Mission Among The Many


The Open Voice Network Interoperability and TrustMark Initiative projects seeks to make voice / Conversational AI work like the web – open, standards-based, unfettered – and for voice / Conversational AI to be worthy of user trust.


The Open Voice Network projects will achieve their vision through the communal development and adoption of industry standards and usage guidelines, industry education and advocacy initiatives, and the development and documentation of voice-centric value propositions.
