HOTWORD VOICE ACTIVATION

2. Tutorials & Examples

Voice activate your flow with any greeting or hotword and start giving voice commands.

Try the following three different continuous listeners that are triggering voice recognition by:

FLOW 1 - Listening for any arbitrary sound louder than the background noise. The sound levels gradually self adapts to different background noise and microphone hardware levels.

FLOW 2 - Listening for any arbitrary sound louder than a set trigger limit. The trigger limit is manually set to a specific background noise and microphone hardware level.

FLOW 3 - Always recognising speech by continuously restarting the recognition every few seconds. The recognition already adapts for background noise and microphone hardware levels but uses more battery, online resources and may fail to hear the command when restarting.

Note 1! Continuous sound listening should now work notwithstanding any illegal sound negative or zero value hardware bugs caught in the sound level block.

Note 2! Not all devices are shipped with an speech recognition engine, try installing Google Voice Search if an UnsupportedOperationException occur.
