Amazon computers in the cloud process the user's request and send back a response or initiate an action. Amazon Echo users utter the wake word when they want to activate and engage with the device.

The term wake word is analogous to hotwordwhich is used to activate the voice user interface VUI on Google Home. While the Echo device is constantly listening, it only records and transmits audio after the wake word has been spoken. Users can review and delete their voice recordings from Amazon servers through the Alexa app or by visiting the Alexa Privacy Settings web page.

End users can also request that Alexa play a short tone to indicate device has heard the wake word and audio is being sent to the cloud.

The Amazon Echo uses deep learningan aspect of artificial intelligenceto teach Echo software how to recognize the wake word. According to Amazon, Echo devices have a recording buffer of just a few seconds, which is just long enough to detect the wake word.

Amazon uses real-world customer voice interactions to help train their neural networking algorithms. The thin ring on the Amazon Echo will turn blue and flash. When the wake word is being changed, the light on the device will briefly flash orange. All Amazon Echo devices have multiple, built-in microphones that help the device ignore background noise and decipher wake words spoken from a distance.

To prevent Alexa from being woken accidentally, comp anies can submit audio samples to Amazon to have specific instances of the wake word ignored. For example, a company making a television commercial about "Alexa" can submit the audio to Amazon.

A friendly introduction to Recurrent Neural Networks

Using a technique called acoustic fingerprinting, Amazon can detect when multiple devices are hearing the same command at around the same time during a television commercial for Alexa, for example. Amazon utilized a recording of the commercial, along with acoustic fingerprinting, to ignore the wake word, "Alexa," whenever Whitaker uttered it. Please check the box if you want to proceed.

Precise is a wake word listener. Like its name suggests, a wake word listener's job is to continually listen to sounds and speech around the device, and activate when the sounds or speech match a wake word. Unlike other machine learning hotword detection tools, Mycroft Precise is fully open source. Take a look at a comparison here. Once that hotword is detected your speech is streamed to the cloud recognition service of your choice - then you get the results. Generally, running npm install should suffice.

This module however, requires you to install SoX. Try out Porcupine using its interactive web demo. You need a working microphone. Try out Porcupine by downloading it's Android demo application.

The demo application allows you to test Porcupine on a variety of wake words in any environment. Mycroft is an Artificial intelligence for everyone.

Perhaps you liked the name Alexa so much, you gave it to your daughter, and now your Echo unit responds to commands directed at your child. If you think that solution sounds clunky or difficult to remember which wake word for which unit? To do so simply open up the Alexa app on your mobile device or navigate to echo. Within the settings menu, select the Echo device whose wake word you wish to change.

Select the wake word. Be aware, as the warning above the selection menu indicates, that it will take a few minutes for the change to take effect and that during this time you will be unable to use your device. If you have more than one Echo or Echo Dot, repeat these steps for each device as wake words are set on an individual basis. With a simple configuration tweak you can switch the wake word on all your devices or split up the wake word between different areas of your home.

Precise is a wake word listener. The software monitors an audio stream usually a microphone and when it recognizes a specific phrase it triggers an event.

When the software recognizes this phrase it puts the rest of Mycroft's software into command mode and waits for a command from the person using the device. Mycroft Precise is fully open source and can be trined to recognize anything from a name to a cough. In addition to Precise there are several proprietary wake word listeners out there. If you are looking to spot a wakeword Precise might be a great solution, but if it's too resource intensive or isn't accurate enough here are some alternative options.

Precise is designed to run on Linux. It is known to work on a variety of Linux distributions including Debian, Ubuntu and Raspbian. Training takes lots of data. These datasets are available for anyone to download, use and contribute to.

A number of models trained from this data are also provided. The official models selectable in your device settings at Home. You can find info on training your own models here. It requires running through the source install instructions first.

If you just want to use Mycroft Precise for running models in your own application, you can use the binary install option. Note: This is only updated to the latest release, indicated by the latest commit on the master branch. If you want to train your own models or mess with the source code, you'll need to follow the Source Install instructions below. First download precise-engine. This will get the latest stable version the master branch.

Note that this requires the models to be built the the same latest version in the master branch. Next, install the Python wrapper with pip3 or pip if you are on Python 2 :. If you would like your models to run on an older version of precise, like the stable version the binary install uses, check out the master branch. Next, install the necessary system dependencies. If you are on Ubuntu, this will be done automatically in the next step. Otherwise, feel free to submit a PR to support other operating systems.

The dependencies are:. In addition to the precise-engine executable, doing a Source Install gives you access to some other scripts. You can read more about them here. One of these executables, precise-listencan be used to test a model using your microphone:. At it's core, Precise uses just a single recurrent network, specifically a GRU.

This project design a micro device, who can detect and classify some wake words in speech. The machine learning functions in the world of audio include wake word detection, audio scene detection, speech recognition, and noise reduction. It is a symbolic math library, and is also used for machine learning applications such as neural networks.

On-device wake word detection engine powered by deep learning. The software used for comparison of systems was the TensorFlow framework. I tested it out by going to the console and training a model. Now, in addition to pushing a button to "start listening", you can now also just say the wake word "Alexa", much like the Amazon Echo.

On-device wake word detection engine powered by Snowboy is an highly customizable hotword detection engine that is embedded real-time and is always listening even when off-line compatible with Raspberry Pi, Ubuntu Linux, and Mac OS X.

This tutorial showed how you can use a wake word to initiate dialog with a virtual assistant that is built using IBM Watson services. In this case, I've just used the wake word, "Yes," but you can imagine customizing it for things that you wanted an interface to wake up with. The wake-word is local, which ensures that the data sent to the cloud is data the user consents to send up.

To summarize, rather than code up a wake word recognizer, we code up a program that can learn to recognize wake words, if we present it with a large labeled dataset.

Take a look at a comparison here. I thought it would be cool to create a personal assistant in Python. A hotword also known as wake word or trigger word is a keyword or phrase that the computer constantly listens for as a signal to trigger other actions. Missing operators are easy to add. The following operators are implemented and After getting the display and worker up and running I started down the path of training my model for keyword recognition.

Even if tract is very far from supporting any arbitrary model, it can run Google Inception v3 and Snips wake word models. This time, the wake word is present in the audio, so we get a much higher score from the inference section. The requested start date was Wednesday, 06 November at UTC and the maximum number of days going backward was You will be using TensorFlow. See Using a custom wake word to see how to configure this. This robot has been a dream robot for me to build for a long time.

Keep in mind, as a best practice you should always export production versions of agents before making changes. Much smaller. The Alexa assistant technology on the Echo is not actually in the device.
