From Siri to Alexa, voice assistants are everywhere, but the technology tends to miss every third word that people with Down syndrome say. Now a new effort is underway to change that.

Google is partnering with the Canadian Down Syndrome Society to collect voice samples from adults with Down syndrome in order to program its algorithm to better decipher the unique speech patterns of this population.

Speech is often altered in those with Down syndrome due to variances in the facial skeletal and muscular systems, according to the Canadian Down Syndrome Society. However, in a small pilot, Google and the nonprofit group found that there were enough similarities across those with the chromosomal disorder to train the voice assistant technology.

“With the help of the Canadian Down Syndrome Society we were able to sample a small group to test whether there were enough patterns in the speech of people with Down syndrome for our algorithm to learn and adapt,” said Julie Cattiau, product manager at Google. “It’s exciting to see the success of that test and move into the next phase of collecting voice samples that represent the vocal diversity of the community. The more people who participate, the more likely Google will be able to eventually improve speech recognition for everyone.”
