Yes, it is very much possible. If you are a beginner, I recommend you use python to do this. You can use PyQt for your GUI, pyttsx and SpeechRecognition for the speech engine (offline). Do the following to install them:
pip install SpeechRecognition
pip install pyttsx
Here’s some code to get you started on the speech recognition in python
import speech_recognition
import pyttsx
speech_engine = pyttsx.init('sapi5') # see http://pyttsx.readthedocs.org/en/latest/engine.html#pyttsx.init
speech_engine.setProperty('rate', 150)
def speak(text):
speech_engine.say(text)
speech_engine.runAndWait()
recognizer = speech_recognition.Recognizer()
def listen():
with speech_recognition.Microphone() as source:
recognizer.adjust_for_ambient_noise(source)
audio = recognizer.listen(source)
try:
return recognizer.recognize_sphinx(audio)
# or: return recognizer.recognize_google(audio)
except speech_recognition.UnknownValueError:
print("Could not understand audio")
except speech_recognition.RequestError as e:
print("Recog Error; {0}".format(e))
return ""
speak("Say something!")
speak("I heard you say " + listen())
