Tests show Google Assistant more apt than Alexa or Siri to understand English spoken with an accent
A speech recognition test run by lab Vocalize.ai pitted digital helpers Alexa, Google Assistant and Siri against each other. The competition was designed to find out which of the three could better understand those speaking English with an accent. The testing measured the trio's response to a native U.S. accent, a moderate Indian accent, and a moderate Chinese accent.

All three did well with isolated word recognition, nailing the U.S. and Indian accents. But Google Assistant proved to be far superior in understanding English with a Chinese accent than the other two assistants. In fact, Google Assistant had a perfect score in all three rounds of this test. For the Speech-In-Noise test that introduced ambient sounds, Google scored a perfect 0% for the U.S. accent, 2% for the Indian accent and 6% for the Chinese accent. Siri's scores were 8% (U.S.),11% (Indian) and 14% (Chinese). Alexa's results were 11%, 15% and 19% respectively. According to Vocalize.ai, the results achieved by Siri and Alexa are the same that you would expect to see from a human with a moderate hearing loss.

Measuring how well each of the three virtual assistants performed when different volume levels were tested, Google Assistant was on top followed by Alexa and Siri. The author of the study said that those with a Chinese accent might have to speak louder for Siri to understand them.

I figured this was the case, based on various videos testing this out on YouTube.

If you owned a mini even its way better than the others. But since your only an Apple guy libra89, then you wouldn't have known. But there is no competition between assistant and Siri. Assistant is so far ahead that Siri is a joke nowadays.

You're incorrect, but thanks for assuming. I do know that the difference is night and day between Siri and Google Assistant.

And water isn't wet. Google assistant doesn't even have legitimate rivals anymore. Only thing I really want them to add is the granularity with on phone commands like Bixby

Not possible.... All phones manufacturers have different skins i.e. Different features and different settings and there layouts.

Google Assistant is so far ahead of Siri and Alexa and Bixby that no more comparisons are even needed. Plus Google Assistant does very well with people that have speech impediments, and pronounce words incorrectly.

Do people really use voice activated assistants regularly past the “wow check this out” phase? I tried it a few times, both Siri and GA, and thought it was ok, but overall thought it was a nice party trick and quickly forgotten.
