POWERING INCLUSIVE SPEECH TECHNOLOGY
AT SCALE
Partner with TWB Voice
to close the global language gap
Billions without voice technology
Speech technology is one of the fastest-growing sectors in AI, but it’s failing 4 billion people worldwide who speak underresourced languages.
Current systems only work well in a handful of globally dominant languages, leaving numerous communities without access to voice-enabled services, information, and digital tools.
While the technical know-how to resolve this is available , the lack of data imposes a barrier to progress.
Speech technology requires extensive voice recordings, transcriptions, and linguistic metadata that don’t exist for the majority of the world’s languages. This leaves social impact opportunities unexplored and communities underserved.

TWB Voice: speech technology for all
TWB Voice is a scalable voice data collection platform that enables organizations to build inclusive speech technology infrastructure.
It leverages our global network of 100,000+ linguists to crowdsource high-quality voice datasets for low-resource languages.
The platform also allows for the onboarding of new contributors in collaborations with partners.
Platform Capabilities
Scalable voice data collection for low-resource languages.
Quality assurance systems with community-driven validation.
Open dataset creation for researchers and developers.
Ethical data governance with informed consent.
Pathways to
self-managed projects.
How we delivered speech technology in northeast Nigeria
In 2025 we successfully collected voice data and built datasets in Hausa, Kanuri, and Shuwa Arabic. From these datasets, we developed speech-to-text and text-to-speech models in Hausa and Kanuri.
Taking on the challenge to activate and mobilize the community, we worked to compile and validate over 111 hours of automatic speech recognition data, and 20 hours of text-to-speech data with 135 contributors.
What voice data can do
Voice datasets enable transformative services across multiple sectors.
Organizations can deploy voice-powered chatbots that answer frequently asked questions on critical topics like health information or agricultural best practices, making essential knowledge accessible regardless of literacy levels.
Additionally, speech-to-text models allow organizations to listen to, transcribe, and analyze incoming information and questions from communities, creating feedback loops that improve service delivery and ensure programs respond to actual community needs.
