Posted by Josh Gordon for the TensorFlow team.
The TensorFlow blog has moved to https://blog.tensorflow.org. Please visit us there.
Thank you to our readers, and to our many guest authors who have created an incredible collection of content representing a diverse body of work. Thanks also to Medium for a great couple of years.
Although we’ve decided to move our blog, articles from the global TensorFlow community — including students, researchers, and companies large and small — will remain an important part of it.
In the future, new articles will be published on https://blog.tensorflow.org. …

Why does “Yo Google” not work with Google Assistant? After all, it’s only one word different from the phrase “Ok Google”. It’s because Google Assistant is listening for two specific words — or Wake Words. Wake Words are critical to the design of low-power machine learning to process data with a computationally inexpensive model to “wake up” the device for full processing. Audio wake words, such as “Ok Google”, are widely used to wake up AI assistant devices before they process speech using more computationally expensive machine learning models.
With the availability of low-power cameras, a popular application includes using a vision sensor with a microcontroller to classify when an image frame contains a person (or any object of interest). We refer to this application as Visual Wake Words because it enables a device to wake up when a human is present, analogous to how audio wake words are used in speech recognition. …
