How can I perform a software update on the Blade?

The Blade has the ability to perform a Software update over-the-air (OTA). Note: performing a an update to the Blade OS will not remove or erase any of your personal data (photos, videos, settings and apps).

To perform a software update on your Blade, ensure the device's battery is charged to at least 50% and is connected to the internet (Wi-Fi).

You can also manually trigger a check for updates via the Blade Software Update menu or on the Companion App.

To check and update your Blade follow the below instructions: 

From the Companion App:

Ensure the Blade is currently connected to the Companion App on your smartphone. Click on Settings tab, scroll down and click on the "Software Update" option.

Clicking on 'Check for Software Update' will check if there is a new Software version available. If no updates are available, you will be prompted with a message indicating 'Your Blade software is up to date'.

What is Speech Recognition?

Speech Recognition is a software program that will listen to a user's voice and perform actions based on spoken commands. Speech Recognition allows the user to navigate around the Blade's UI and launch certain apps without touching the device. Individual apps can extend this functionality by using the Vuzix Speech SDK.

How do I enable Speech Recognition on the Blade?

Speech Recognition can be enabled from the Settings app on the Blade or by using the Blade Companion App. On the Blade, go to Settings > Device > Speech Recognition and select the microphone icon to enable or disable Speech Recognition. In the Blade Companion App, Speech Recognition can be enabled or disabled on a linked and connected Blade by going to the Settings tab > Speech Recognition and tapping the "Enable" control.


When Speech Recognition is first enabled, it will be listening for the trigger phrase "Hello Vuzix". After Speech Recognition hears the phrase "Hello Vuzix", an icon showing a microphone inside a circle will appear in the lower-left corner of the screen. This indicates that Speech Recognition is ready to listen for your commands. When you are finished using Speech Recognition, use the command "Voice Off" to deactivate Speech Recognition. Upon hearing this phrase, the listening icon should disappear and Speech Recognition will resume listening for the trigger phrase "Hello Vuzix". Speech Recognition will automatically deactivate itself after a certain amount of time with no voice activity.


Speech Recognition can also be activated by using a tap on the left side of the Blade. This feature must be enabled on the Speech Recognition page in the Settings app before it will be available. Activating Speech Recognition using a tap operates the same as saying the trigger phrase "Hello Vuzix". The sensitivity of this trigger can also be adjusted on the Speech Recognition page in the Settings app.

What Speech Recognition commands can I say?

Commands fall into two categories: navigation and actions.

Navigation commands such as "move right" or "move left" will act much the same as a touchpad swipe in those directions. These are associated with a standard keyboard key press. Action commands such as "take a picture" or "go to sleep" will perform a specific action that does not map to a keyboard key press. These will do more complex actions, like launching an app or putting the device to sleep. Some example commands are listed below:

  • Navigation: move left, move right, go back, go home, select this
  • Action: take a picture, start recording, go to sleep, get assistant

A full list of commands is available in the Speech Recognition page in the Settings app, or in the Speech Recognition section of the Settings tab in the Blade Companion App.

Can I make my own Speech Recognition commands?

The base set of speech commands cannot be changed. However, developers who are writing an app for the Blade can use the Vuzix Speech SDK to interact with Speech Recognition and set their own custom vocabulary of commands. These commands will not be available to other apps running on the device.

Does Speech Recognition record what I say?

Speech Recognition needs to capture audio input from the microphone in order to process spoken commands. Speech Recognition does not store this audio data in any form after processing a command.

Does Speech Recognition require an internet connection?

Speech Recognition on the Blade operates entirely offline and does not require an internet connection.

Can I use Speech Recognition to launch a digital assistant?

If a digital assistant is installed on the Blade, then the command "get assistant" will launch it. While the assistant is listening to the microphone, Speech Recognition will not be available. Note that digital assistants may require internet access and may record your audio data to the cloud.

Can I use other apps that record audio, like the Camera, while using Speech Recognition?

Speech Recognition cannot be used at the same time as another app that records audio. While Speech Recognition is enabled, any app that requests audio input will cause Speech Recognition to stop listening. Once that app is finished using the audio input, Speech Recognition will be automatically re-enabled.

What is the maximum length video I can record?

  • Videos can be recorded up to a 4GB limit 
  • Dependent on settings selected on the Blade, this can range from 1.5-2.5hrs

Do I need an Amazon Prime Account to use Alexa on the Blade?

No, a standard Amazon account will give you access to the majority of the features offered with the Alexa service on the Blade.

Why is there no sound coming out of my Vuzix Bluetooth headphones?

To properly connect the Vuzix Blade to the included Bluetooth headphones, first ensure that the Blade has the Bluetooth Audio Mode set to Audio Source.

Secondly, navigate into the Bluetooth headset icon to ensure the Headset and Audio Source indicators are listed as connected. (If disconnected, tap to connect)

Lastly, confirm the volume setting of the device, adjust to your preference.
