Kivy sample app with speech recognition

[Andreas Jung]

Hi there,

my plan is to write an iOS application with Kivy providing speech recognition (using the Speech-to-Text API of Google) in order to speak to my home :-) ..means my home automation should listen to me.

https://pypi.python.org/pypi/SpeechRecognition/

seems to do the job.

I am current primarily looking for some sample (Kivy) code for recording a command through the microphone (iOS) and storing it as WAV.

Any hint for the Kivy clueless?

Thanks

Andreas

Hi, here is mine.

main.py

from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.clock import Clock, mainthread
import speech_recognition as sr
 
class Principal(Screen):
    def BtnEscuchar(self):
        self.ids.lblMensaje.text = "Say something!"
        Clock.schedule_once(lambda d: self.GetAudio(), 0)
 
    def GetAudio(self):
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
        self.audio = audio
        try:
            self.ids.lblMensaje.text = "Google Speech Recognition thinks you said " + r.recognize_google(audio, language = 'es')
        except sr.UnknownValueError:
            print("Google Speech Recognition could not understand audio")
        except sr.RequestError as e:
            print("Could not request results from Google Speech Recognition service; {0}".format(e))
 
class testspkApp(App):
 
    def build(self):
        sm = ScreenManager()
        self.sm = sm
        sm.add_widget(Principal(name='Principal'))
        return sm
 
    def on_pause(self):
        return False
 
 
main = testspkApp()
main.run()
