programming in Choregraphe via Python

  • enter only one box Python Script
  • edit its contents via double click:
    • to __init__ add:
      self.tts = ALProxy('ALTextToSpeech')
    • to onInput_onStart add:
      self.tts.say("Ahoj, jak se máš?")
  • add Czech into Project Properties
  • save the project and run in on a virtual robot

speech input via Python

  • in __init__ add:
            self.speech = ALProxy("ALSpeechRecognition")
  'Running on virtual robot')
            self.speech = None
  • process speech accordingly
    def get_answer(self, reactions):
        if self.speech is None:
            return (random.choice(reactions.keys()))
            self.speech.setVocabulary(reactions.keys(), False)
  'Speech recognition engine started')
    def onInput_onStart(self):
        self.tts.say("Ahoj, jak se máš?")
        reactions = {
            'dobře':  'to je super!',
            'špatně': 'doufám, že to brzo bude lepší',
            'nevím': 'tak to určitě nebude tak zlé',
        answer = self.get_answer(reactions)
        react = reactions.get(answer)'answer={}, react={}'.format(answer, react))
