Toward more scalable speech technology for African languages
Learn how we are exploring the potential of synthetic data to improve automatic speech recognition for low-resource African languages Africa is home to over 2,300 languages, and the majority of them are unsupported by both automatic speech recognition (ASR) to transcribe speech and speech synthesis to generate it. Developing speech technologies requires voice datasets: collections […]

From words to impact: an evaluation of CLEAR Global’s work in northeast Nigeria from 2017 to 2025
This report presents an evaluation of our northeast Nigeria program between 2017 and 2025. The program is on standby as of June 2025 due to budget constraints and the global downscaling of humanitarian efforts. This assessment examines eight years of efforts to bridge communication gaps and improve language access for marginalized communities in one of […]
