MLCommons, a nonprofit AI safety working group, has collaborated with AI development platform Hugging Face to release one of the world's largest collections of public domain voice recordings for AI research. Dubbed Unsupervised People's Speech, the dataset contains over a million hours of audio spanning at least 89 different languages.

The motivation behind creating this vast dataset, according to MLCommons, is to support research and development in various areas of speech technology. By providing a massive repository of voice recordings, the organization aims to facilitate broader natural language processing research, particularly for languages other than English. This, in turn, could lead to more inclusive communication technologies globally.

The dataset is expected to have a significant impact on the research community, enabling the development of more accurate speech recognition models, improved speech synthesis, and novel applications in speech technology. MLCommons anticipates that Unsupervised People's Speech will pave the way for breakthroughs in low-resource language speech models, enhanced speech recognition across different accents and dialects, and innovative uses of speech synthesis.

However, experts caution that datasets like Unsupervised People's Speech can pose risks for researchers who utilize them. One of the primary concerns is biased data, which can perpetuate prejudices in AI systems. In this case, the recordings in Unsupervised People's Speech were sourced from Archive.org, a nonprofit organization with a predominantly English-speaking contributor base. As a result, the majority of the recordings are in American-accented English, which could lead to biased AI models.

For instance, AI systems trained on Unsupervised People's Speech might struggle to transcribe English spoken by non-native speakers or have difficulty generating synthetic voices in languages other than English. Furthermore, there is a possibility that some recordings may have been included without the knowledge or consent of the individuals involved, raising concerns about privacy and data ownership.

According to an MIT analysis, hundreds of publicly available AI training datasets lack licensing information and contain errors. This highlights the need for creators to have more control over how their work is used in AI research. Ed Newton-Rex, CEO of Fairly Trained, a nonprofit focused on AI ethics, argues that creators should not be required to "opt out" of AI datasets, as this places an undue burden on them.

MLCommons has committed to updating, maintaining, and improving the quality of Unsupervised People's Speech. Nevertheless, developers are advised to exercise caution when working with this dataset, taking steps to mitigate potential biases and ensure that the data is used responsibly.

In conclusion, the release of Unsupervised People's Speech marks a significant milestone in the development of AI research, but it also underscores the importance of responsible data collection and use. As AI continues to permeate various aspects of our lives, it is crucial that we prioritize ethical considerations and strive to create more inclusive, unbiased AI systems.
