can't recognize words correctly

[iProMC]

Hello, when I start my project and say for example: (open google). the project can't recognize words correctly and give me a random word.

my codes
#start
import os
import sys
from playsound import playsound
import pyaudio
import webbrowser
import datetime
import wikipedia
import speech_recognition as sr
from pocketsphinx import pocketsphinx, Jsgf, FsgModel

rootdir = os.path.dirname(sys.modules['main'].file)
rootdir2 = os.path.dirname(sys.modules['main'].file)
rootdir3 = os.path.dirname(sys.modules['main'].file)
rootdir +="\sounds"
rootdir2 +="\env\Lib\site-packages\speech_recognition\pocketsphinx-data\en-US"
rootdir3 +="\config"

grammar_file = "contact.gram"

#grammar_path = os.path.join(rootdir3 + "\contact.gram")
#fsg_path = "{}.fsg".format(grammar_path)

#print("Grammar Filepath: {}".format(grammar_path))
#print("FSG Grammar Filepath: {}".format(fsg_path))

Create decoder object

config = pocketsphinx.Decoder.default_config()
config.set_string("-hmm", os.path.join(rootdir2, 'acoustic-model'))
config.set_string("-lm", os.path.join(rootdir2, 'language-model.lm.bin'))
config.set_string("-dict", os.path.join(rootdir2, 'pronounciation-dictionary.dict'))
config.set_string("-logfn", os.devnull)
decoder = pocketsphinx.Decoder(config)

Convert grammar

grammar_path = os.path.abspath(os.path.dirname(grammar_file))
grammar_name = os.path.splitext(os.path.basename(grammar_file))[0]
fsg_path = "{0}/{1}.fsg".format(grammar_path, grammar_name)
if not os.path.exists(fsg_path):
jsgf = pocketsphinx.Jsgf(grammar_file)
rule = jsgf.get_rule("{0}.{0}".format(grammar_name))
fsg = jsgf.build_fsg(rule, decoder.get_logmath(), 7.5)
fsg.writefile(fsg_path)
print('Successful JSFG to FSG conversion!!!')

Pass the fsg file into the decoder

decoder.set_fsg(grammar_name, fsg)

#2
r = sr.Recognizer()
mic = sr.Microphone()
with mic as source:
audio = r.listen(source)
result = r.recognize_sphinx(audio)
print(result)
with open('contact.gram') as myfile:
if result in myfile.read():
print('Blahblah')
if result =="hello":
print("You said Hello")
playsound(rootdir + "\test.mp3")

elif result == "time":
  print("BETA")

elif result == "what then":
  print("opening youtube")
  playsound(rootdir + "\\test.mp3")
  webbrowser.open("youtube.com")

elif result == "open google":
  print("opening google")
  playsound(rootdir + "\\test.mp3")
  webbrowser.open("google.com")
