MIT Technology Review’s The Download weighs voice imitation and AI in classrooms
Markdown · JSON · Original source
On July 15, 2025, MIT Technology Review’s The Download newsletter discusses machine unlearning for AI-generated voices and a planned classroom initiative. Peter Hall describes a technique that could make AI models forget specific voices, presenting it as a possible way to curb audio deepfakes used for fraud or scams. James O'Donnell reports that , Microsoft, and announced a partnership with a teachers’ union to train teachers to use AI for teaching and school tasks. He warns that clear evidence of a net benefit for students is lacking and questions whether the companies funding the initiative will advise teachers honestly about when not to use AI. The newsletter reports plans to begin training in the fall; it does not establish what the training will achieve. Whether machine unlearning can effectively prevent voice misuse, and whether classroom AI benefits students, remain open.

Open question
What evidence will show whether the classroom initiative benefits students, and whether machine unlearning can curb audio deepfakes?
Source-stated
Peter Hall says machine unlearning could let AI models forget specific voices, potentially helping stop audio deepfakes used for fraud or scams.
A new technique known as “machine unlearning” could be used to teach AI models to forget specific voices.
Source-stated
James O'Donnell reports that OpenAI, Microsoft, and Anthropic announced a partnership with a teachers’ union to train teachers in AI use for classrooms and school tasks.
On July 8, OpenAI, Microsoft, and Anthropic announced a $23 million partnership with one of the largest teachers’ unions in the United States to bring more AI into K–12 classrooms.
Source-stated
James O'Donnell says clear evidence that AI can be a net benefit for students is lacking, and questions whether the companies funding the initiative will give honest advice about when not to use it.
There's a lack of clear evidence that AI can be a net benefit for students, and it's hard to trust that the AI companies funding this initiative will give honest advice on when not to use AI in the classroom.

attribution — pass: This is one MIT Technology Review newsletter issue that comments on stories in its own words, not a bare listing. The reading correctly credits the unlearning item to Peter Hall and the classroom item to James O'Donnell, matching the bylines.
This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.
summary — pass: The reading leads with the two lead items and names the actors. It explains machine unlearning in plain terms as making AI models forget specific voices. It links audio deepfakes to fraud and scams. It keeps O'Donnell's skeptical force about evidence and trust. It omits the $23 million figure, the K–12 scope and the 'God help them' aside, but these omissions do not prevent understanding. The question follows from the source.
Machine unlearning instead asks whether an AI can be made to forget a piece of information that the company doesn’t want it to know.
date — pass: July 15, 2025 matches the UTC day of originalPublished. The fall training start is reported as a plan, not an outcome. Later-dated Deep Dive teasers on the captured page, such as the 377 math findings item, are not used by the reading. The kind is publisher-page, so no archive disclosure is required. The modifiedAt value falls before publication.
They will train teachers at a New York City headquarters on how to use AI both for teaching and for tasks like planning lessons and writing reports, starting this fall.
support — pass: Each claim matches its excerpt. The 'could' framing for unlearning and deepfakes is kept. The partnership and the doubts about evidence and trust remain attributed to O'Donnell. The limitations rightly note that outcomes are unreported, and no unsupported benefits or costs are added.
This could be an important step in stopping the rise of audio deepfakes, where someone’s voice is copied to carry out fraud or scams.
media — pass: No media was selected, and no verified candidates were supplied. A null media ID is appropriate.
