google-speech-to-text API transcription response gets numbers instead words

Question

I use the code: which works fine with a sound file in the English language but why in a sound file in another language when I update the code to recognize another language accordingly I get the results in the response in numbers and not words, can you please help, I am a new student in this subject?, thanks

from google.cloud import speech

speech_client = speech.SpeechClient.from_service_account_file('key.json')
media_file_name = 't2.wav'
with open (media_file_name,'rb') as f:
byte_data_wav = f.read()
audio_wav =speech.RecognitionAudio(content=byte_data_wav)
config_wav = speech.RecognitionConfig(
sample_rate_hertz=44100,
enable_automatic_punctuation = True,
language_code ='iw-IL',
audio_channel_count=1
)
response_wav = speech_client.recognize(
config = config_wav,
audio  =  audio_wav
)
print(response_wav)
