Hello,

Something i never understood if why with an if and else statement there is that repeat effect.
Inside the try except the voice is saying "le fruit a été ajouté dans le panier" if its fraise or pomme word and saying "le légume a été ajouté au panier" if its a vegetable.
Why is it jumping to the else if there is no vegetable?

from speech_recognition import Recognizer, Microphone
from gtts import gTTS
import subprocess

recognizer = Recognizer()

# On enregistre le son

with Microphone() as source:
    print("Réglage du bruit ambiant... Patientez...")
    recognizer.adjust_for_ambient_noise(source)
    print("Vous pouvez parler...")
    recorded_audio = recognizer.listen(source)
    print("Enregistrement terminé !")
    
# Reconnaissance de l'audio

try:
    print("Reconnaissance du texte...")
    text = recognizer.recognize_google(
            recorded_audio, 
            language="fr-FR"
        )
    print("Vous avez dit : {}".format(text))
    hotword= ["pomme","fraise"]
    for h in hotword:
        if h in text:
            tts = gTTS(u"le fruit a été ajouté dans le panier", lang="fr")
            tts.save('out.mp3')
            cmd = ['mpg321', '-q', 'out.mp3']
            subprocess.call(cmd)
        else:
            tts = gTTS(u"le légume a été ajouté au panier", lang="fr")
            tts.save('out.mp3')
            cmd = ['mpg321', '-q', 'out.mp3']
            subprocess.call(cmd)
except Exception as ex:
    print(ex)

Thank you

This is not what the code does. The code says "le fruit a été ajouté dans le panier" for every hotword that is found in the text and it says "le légume a été ajouté au panier" for every hotword that is not found in the text. The code does not know about fruits and vegetables.

i solve the problem this way but there must be a way not to repeat all the code so many times:

if "pomme" in text:
        tts = gTTS(u"le fruit a été ajouté dans le panier", lang="fr")
        tts.save('out.mp3')
        cmd = ['mpg321', '-q', 'out.mp3']
        subprocess.call(cmd)
    if "fraise" in text:
        tts = gTTS(u"le fruit a été ajouté dans le panier", lang="fr")
        tts.save('out.mp3')
        cmd = ['mpg321', '-q', 'out.mp3']
        subprocess.call(cmd)
...

I thought the h in hotword was looping everyword in the list and if h == text (so "pomme" in list = the word text when = "pomme" than it excute the script?

You seem to have a hard time with code that needs to remember something. In your example you need to rember if you found one of the hotwords in the text. If a hotword was found you perform one action, else you perform another. The important thing is to evaluate the condition first, the perform the action. In your first example the evaluation and performing action were intertwined.

    # This is the search
    found_word = None
    for h in hotword:
        if h in text:
            found_word = h
            break

    # Perform the action based on search result
    if found_word
        tts = gTTS(u"le fruit a été ajouté dans le panier", lang="fr")
        tts.save('out.mp3')
        cmd = ['mpg321', '-q', 'out.mp3']
        subprocess.call(cmd)
    else:
        tts = gTTS(u"le légume a été ajouté au panier", lang="fr")
        tts.save('out.mp3')
        cmd = ['mpg321', '-q', 'out.mp3']

This is kind of ugly, so Python has a shorthand.

def contains(string, substrings):
    if any(s in string for s in substrings):
        print(f"{string} contains one of these {substrings}")
    else:
        print(f"{string} does not contain any of these {substrings}")

contains("blast", ["first", "last"])
contains("blast", ["begin", "end"])

Functionally this is identical to:

def contains(string, substrings):
    found = False
    for s in substrings:
        if s in string:
            found = True
            break
    if found:
        print(f"{string} contains one of these {substrings}")
    else:
        print(f"{string} does not contain any of these {substrings}")

contains("blast", ["first", "last"])
contains("blast", ["begin", "end"])

Another way to solve your particular problem is to use sets. You have a set of words and a set of hotwords. If the insersection of words and hotwords is not empty, that means one of the hotwords is in words.

if set(words).intersection(set(hotwords)):
    # do found stuff
else:
    # do not found stuff

In the last case it always jump to the else. Even if i say a word in the list:
Tomate is a fruit but it reply it is a vegetable (else) .

for the function i dont get where the blast is coming from and what is the use of contains.

from speech_recognition import Recognizer, Microphone
from gtts import gTTS
import subprocess

recognizer = Recognizer()

# On enregistre le son

with Microphone() as source:
    print("Dite un fruit ou un légume dans le microphone")
    print("Réglage du bruit ambiant... Patientez...")
    recognizer.adjust_for_ambient_noise(source)
    print("Vous pouvez parler...")
    recorded_audio = recognizer.listen(source)
    print("Enregistrement terminé !")
    
# Reconnaissance de l'audio

try:
    print("Reconnaissance du texte...")
    text = recognizer.recognize_google(
            recorded_audio, 
            language="fr-FR"
        )
    print("Vous avez dit : {}".format(text))
    words = text
    hotword = ["fraise", "pomme","tomate"]
    def contains(string, substrings):
        found = False
    for s in substrings:
        if s in string:
            found = True
            break
        if found:
            tts = gTTS(u"le fruit a été ajouté dans le panier", lang="fr")
            tts.save('out.mp3')
            cmd = ['mpg321', '-q', 'out.mp3']
            subprocess.call(cmd)
        else:
            tts = gTTS(u"le légume a été ajouté au panier", lang="fr")
            tts.save('out.mp3')
            cmd = ['mpg321', '-q', 'out.mp3']
            subprocess.call(cmd)
        
contains("blast", ["text"])
contains("blast", ["fraise", "pomme","tomate"])
  except Exception as ex:
    print(ex)

The set() approach will only find matching words if there are matches to be found. "tomato" does not match "Tomato", nor does it match "tomatoes" or "I like that with tomato please". Verify that "words" is a list of words and not a string that contains words.

My "any" example finds substrings in a word, not words in a list. It is not directly applicable to your problem, but it does a nice job demonstrating how "any" works.

I cant figure out why it is not working.

Quote: Verify that "words" is a list of words and not a string that contains words.

I am not sure what you meant by string that contains words.

Do you understand the difference between a list of strings and a single string?

the list of strings: hotword = ["fraise", "pomme","tomate"]
a single string : a = "Hello"

the variable text is a string?
I mean it returned a string, the string pomme. But i cant confirm it was under the form of a string.

it becomes a string representation here: print("Vous avez dit : {}".format(text))

does it sees a string here: if set(words).intersection(set(hotword)):

i am not sure

Also i am trying to rerun the program so the user can tell another phrase after 15 seconds. It has been changed for phrase but it doesnt seems to recognize phrases.

A list of words is ["Vous", "avez", "dit", "pomme"]. A string of words is "Vous avez dit : pomme". You can use set intersection to find "pomme" in a list of words. You cannot use it to find the substring "pomme" in a longer string (a string of words).
