Using the HMT

Speech Keyboard HMT Interaction



Cloud Dictation in Release 12

Release 12 for the HMT introduces a new cloud dictation engine for RealWear’s speech keyboard that delivers more accurate, responsive, and grammatically correct results. User who have used the HMT previous to Release 12 will notice very few differences with this dictation method, and developers who have already implemented dictation in their applications will not need to make any changes to take advantage of this improved cloud dictation.

Local dictation is available in English, German and Mandarin Chinese. For all other languages, only cloud dictation is available.

To switch from local dictation, say the following commands, then select your choice:

Speech Keyboard

Speech Keyboard is the default method by which text may be entered into a text field using the HMT-1 or HMT-1Z1.

Whenever a text entry screen is brought into focus or selected, the hands-free keyboard is displayed overlaying part of the application.

Speech Keyboard Help

Speech keyboard provides various input methods:

  • Normal Entry Keyboard:Use words that stand for each letter, such as “Alpha” for the letter “a”.
  • Secure Entry Keyboard: For secure text such as passwords, enter text without saying the character name.
  • ABC Mode Keyboard:  Spell out words one character at a time.  
  • Scan Code: Scan a code generated by a RealWear code generator, such as the companion app, to enter in a string of text.
  • Dictation: A speech-to-text system interprets your voice and writes words.

Normal Entry Keyboard

Using the Normal Entry Keyboard you may enter letters, numbers, or symbols.

The Normal Entry Keyboard opens in the letter list. Scroll left or right to see the code word associated with the character.

To switch to the Numbers keyboard, say ‘NUMBERS’.

To switch to the Symbols keyboard, say ‘SYMBOLS’

Note, the letter does not have to be in the focus square in order to say each code word. You may speak the phonetic commands for characters either individually or as a group.  For instance, you could enter one character at a time by saying ‘ROMEO’, then saying ‘ECHO’ once the ‘R’ character has registered, or you could enter an as many letters as is needed with one command.

EXAMPLE: Saying “ROMEO ECHO ALPHA LIMA WHISKEY ECHO ALPHA ROMEO” in one breath without break will enter ‘realwear’ into the text field.

Remember the command ‘SPACEBAR’ is part of all three Normal Entry lists; you can say that at any time to add a space.

Secure Entry Keyboard

When a password field is selected, the Secure Entry keyboard appears.  This means that phonetic speech commands are disabled, and the user must use head movements, left or right, to highlight a character. When the desired character is in the focus square, say ‘SELECT’ to choose that letter.

ABC Mode

Please see Speech Keyboard – ABC Mode for more information.

Scan Code

Saying the command ‘SCAN CODE’ opens the barcode reader and allows the user to scan a QR Code for remote keyboard entry using the RealWear Companion app on a mobile phone. This is convenient for passwords and long strings of text.  Simply open the RealWear Companion app, select ‘Remote Keyboard’, enter text and tap on the QR Code.  From the HMT keyboard say ‘SCAN CODE’, then scan the QR Code visible on the screen of your smartphone.  You can also access the ‘SCAN CODE’ option by saying ‘MORE OPTIONS’.


For Speech-to-Text entry, say ‘Dictation’, then immediately begin speaking freely.  Dictation is cloud-based for all languages, so an internet connection may be required.  Some languages support local dictation as well.  You can also access the ‘DICTATION’ option by saying ‘MORE OPTIONS’.  For more information, please visit


NOTE: If the keyboard becomes hidden or accidentally closed, use the “SELECT ITEM #” command to select the text field again and the speech keyboard will reappear.


If entering a password for WiFi authentication, simply say “PASSWORD” to activate the speech keyboard.
