How was the dataset collected?
Every take is recorded on our custom consumer applications, where participants are paid for their contributions.
Contributors consent to the recording and licensing of their contributions for AI research and commercial development. Our contributor agreements explicitly cover model training and evaluation, speech recognition, text-to-speech, voice synthesis, voice cloning, and digital replicas, subject to each contributor’s consent and the applicable dataset license.
Why are we open sourcing it?
Everyone deserves to be understood. For technology to benefit humanity, it needs to reach people in the languages they call their own. We're sharing Basis Global Emotions so researchers and builders everywhere can develop models that understand and express emotion in more of the world's languages, including those often overlooked in speech research.
This release, like all our open source releases, is free for commercial and research use.
What other data does Basis gather?
Basis works with the world's leading research labs to build custom datasets across voice, video, and interaction, shaping each collection around the labs' research goals and data needs. Our voice datasets include emotionally steered speech, multi-speaker conversations with or without video, bilingual recordings, and more. We also provide transcriptions, human annotations, and pairwise human preferences at unmatched scale through our contributor network of over a million users.
