Jen did you run the commands posted on the website?
To set up voice access, head over to WebADB and follow the instructions to connect your device. Then go to the Interactive Shell section. Run the following commands in order
am startservice com.android.cts.apps.accessibility.voiceaccess/com.google.android.apps.accessibility.voiceaccess.JustSpeakService
settings put secure enabled_accessibility_services com.android.cts.apps.accessibility.voiceaccess/com.google.android.apps.accessibility.voiceaccess.JustSpeakService
settings put secure accessibility_enabled 1
pm uninstall -k --user 0 com.lge.voicecommand`
If you get an error when running any of the above commands, ignore it and proceed to run the remaining commands. This is normal and Voice Access will still work after running all of the commands.
Voice access will now work!! Enjoy.
