Can we activate stt without using wake word?

kasturi · March 3, 2021, 11:09pm

Is it possible to use speech recognition, skills and tts on mycroft without using a wake word?
Also, is it possible to use an activation flag provided externally through a python script to trigger the stt part instead of a .pb file ?
Thank you

You can use the message bus for this. so you can start at any point. https://mycroft-ai.gitbook.io/docs/mycroft-technologies/mycroft-core/message-types#recognizer

Hey there, it certainly is.

On our end-user devices (Mark 1 and Mark II) there are action buttons on top that you can push to activate the listener.

Emitting a bus message won’t get the same result. You would need to create a buttonPress signal. Here’s where that is handled in the Mark II currently:

        new_leds.append( self.palette.BLACK )
    self.leds.set_leds( new_leds )
    self.cancel_watchdog()
    self.watchdog = threading.Timer(self.watchdog_timeout,
                                    self.handle_watchdog)
    self.watchdog.start()
    if self.client_volume_handler != None:
        self.client_volume_handler(vol)
def handle_action(self):
    LOG.debug("Mark2:HardwareEnclosure:handle_action()")
    # debounce this 10 seconds
    if time.time() - self.last_action > 10:
        self.last_action = time.time()
        if self.overide_action is not None:
            self.overide_action()
        else:
            create_signal('buttonPress')
def handle_mute(self, val):

Thanks, I could do it using the message bus.
