New throat patch can turn muscle movements into speech

PARIS — A brand new adhesive patch might someday assist individuals with voice problems converse once more by utilizing synthetic intelligence to learn the actions of their throat muscle tissue and switch them into speech, researchers mentioned Tuesday.

The small, stretchy patch is powered solely by the muscle actions, the US-based researchers revealed in a research in Nature Communications.

Attached to the pores and skin, the patch converts the actions of the larynx muscle tissue into electrical alerts, that are in flip translated into speech by a machine studying algorithm, a type of AI.

Then a speaker performs the sentences the individual supposed to say aloud—although the prototype can at the moment solely relay sure pre-recorded phrases.

Crucially, the patch works without having to select up on the vibrations of an individual’s vocal cords, which means it could assist restore the speech of individuals with broken vocal cords, lead research writer Ziyuan Che of the University of California, Los Angeles advised AFP.

Nearly a 3rd of individuals undergo at the least one voice dysfunction of their lifetime, in line with the research.

Existing therapies for severe voice issues, similar to handheld units like an electrolarynx, could be “inconvenient, uncomfortable, or invasive,” the researchers mentioned.

95% accuracy

The waterproof patch is roughly the scale of a giant coin and weighs simply seven grams.

Che in contrast its texture to that of a rubber glove.

To take a look at the machine, eight volunteers with out voice problems have been requested to each converse and whisper 5 sentences together with “Merry Christmas,” “I love you” or “I don’t trust you.”

They learn out the phrases whereas standing, strolling and working, to indicate the patch labored whereas on the transfer.

The machine precisely predicted what the volunteers have been saying roughly 95 % of the time, in line with the research.

Some phrases that transfer throat muscle tissue in an identical method—such because the phrase “make” and the identify “Mark”—might be tough for the patch to inform aside, Che mentioned.

“But those two words usually appear in a long sentence like ‘I am going to make dinner,’ or ‘How you doing Mark?'” Che added.

This permits the machine—which interprets sentences, not simply phrases—to select up the context.

Che cautioned that the prototype was nonetheless years away from probably being obtainable to sufferers.

And all of the sentences that may at the moment be performed by the machine must be pre-recorded, which “would limit the application of our device,” Che acknowledged.

But he believed that extra superior algorithms would permit the patch to translate larynx muscle actions “without the need of pre-recording the voice signals.” — AFP
