Because different words have very different best potential performance characteristics when used as wake words.
We would have liked to enable fully custom wake words, but it would have led to bad user experiences with the device either failing to wake up too often (false negatives) or having too many false positives or both.
So we compromised by enabling more than one, but not full choice.
- mc32 6y agoThanks for the insight. Is it difficult to fingerprint a sound bite? Have people repeat it several times and again for each user that wants to use the custom wake word?
- Daegalus 6y agofrom my observations of the masses that Alexa and co try to cater to, that's too much work or too technical. we have to remember the average joe/jane don't know what a browser is.
- sib 6y agoIt's not so much the "fingerprinting" - it's more that there are some words ("type 1") that have many relatively frequent words that sound like them, and there are other words ("type 2") that only have a very few other words (and infrequent ones at that) that sound like them. Type 2 words make better potential wake words. (That's not the whole story, but I think it's good model.)
