The TWB Voice Playbook is a practical guide to planning and managing voice data collection projects for low-resource languages. It is aimed at both new and experienced teams and covers the full process, from setting up the project to publishing your dataset. 

The playbook draws on CLEAR Global’s experience developing and running TWB Voice, a platform launched in 2025 to collect and validate voice recordings from many contributors. These recordings help build voice technologies like Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) for low-resource languages. 

While the playbook reflects lessons learned from our work in TWB Voice, it also offers guidance relevant to organizations and communities who want to collect voice data through other platforms or initiatives.
