Reconnaissance vocale

Bonjour,

Ca paraît se faire.
Ici :

Quelqu’un(e) a-t-il déjà fait cela avec ce module ?

Je l’installe ainsi :

$ pip3 install SpeechRecognition

Il faut aussi le module “pyAudio” :

$ pip3 install --user pyAudio

Et au final j’obtiens une erreur :

Comment dois-je procéder ?

Le README de PyAudio conseille soit de l’installer via apt (si tu as la chance d’utiliser Debian). Si tu es obligé de l’installer via pip le README te conseille d’installer les dépendances :

Alternatively, if the latest version of PyAudio is not available, install it using pip. Be sure to first install development libraries for portaudio19 and python3.

Si tu as la chance d’utiliser Debian, un simple apt install portaudio19-dev python3-dev devrait suffire.

Avec une base Debian, par chance oui.

Le paquet python3-pyaudio s’installe correctement.
Merci pour ce rappel.

Mais le petit script .py pour test échoue.

Je suis très curieux de savoir si les résultats sont probants même si
c’est en langue anglaise.

Bonjour Julien,

Le script est celui-ci :

#!/usr/bin/python3.10

import speech_recognition as sr
import pyaudio

def listen():
     r = sr.Recognizer()
     mic = sr.Microphone(device_index=1)
     with mic as source:
         audio = r.listen(source, timeout=10)
         return r.recognize_google(audio)
print(listen())

listen()

Dans un autre exemple la ligne “index = pyaudio.get_device_count() - 1”
provoque l’erreur :

Traceback (most recent call last):
   File "/home/aciah/./test-speechrecognition2.py", line 6, in <module>
     index = pyaudio.get_device_count() - 1
AttributeError: module 'pyaudio' has no attribute 'get_device_count'

Problème de version de pyaudio ?

Merci Julien pour votre écoute

Probable, c’est une bonne piste en tout cas.

Tu peux utiliser apt-cache policy python3-pyaudio pour savoir quelle version tu as, et fais bien attention à lire la doc de ladite version, par exemple via un apt install python-pyaudio-doc si leur doc en ligne ne permet pas de choisir la version facilement.
