I would like to play sound in octave with pulseaudio. I saw this post but the octave audio management is changed in the new releases and it is not longer possible to use paplay like say that post, I have the version 4.2.1-4
Now when I try to use sound or audiolayer functions I get these errors:
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe

connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=No such file or directory)
attempt to connect to server failed
And no sound is played, next, if I retry to use sound I don't get error and it waits for the sound duration, however it keep to not play sound.
It seems it would like to use ALSA, but I'm using pulseaudio what can i do?
EDIT:
I notice that sometimes the error message change and it say:
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave

i have this code:

voices = engine.getProperty('voices')
engine.setProperty('voice', voices[0].id)
newVoiceRate = 200
engine.setProperty('rate', newVoiceRate)

engine.say(audio)
engine.runAndWait()
speak("hello this is a program")

My SO is Manjaro :)
When i run below python script it shows some error.
import speech_recognition as s
sr=s.Recognizer()
print("Please, speak now....")
with s.Microphone() as m:
audio=sr.listen(m)
query=sr.recognize_google(audio,language='eng-in')
print(query)
I tried almost all solution available online but still my problem is not solved.
The error massage in command line is:

But when i run this python script on jupyter-notebook or Pycharm it does't show any error but still not taking any input from microphone(but microphone start) and also not showing any output.
I started making a virtual assistant program taking help from this YouTube video(https://www.youtube.com/watch?v=AGatX_8gaeM).
I made the basic speech recognition code but it isn't responding to voice inputs to both internal microphone and external microphone.
When I run the program
import speech_recognition as sr
from gtts import gTTS
def recordAudio():
record=sr.Recognizer()
with sr.Microphone() as source:
print('Say something!')
audio=record.listen(source)
data=''
try:
data=record.recognize_google(audio)
print('You said: {}'.format(data))
except sr.UnknownValueError:
print('Ran into some unknown error retry....')
recordAudio()
except sr.RequestError:
print('Ran into request error retry....')
recordAudio()
except:
print('Ran into something other than UnknownValueError or RequestError')
recordAudio()
but this happens:

Can somebody help me out with this.
You have to connect a microphone on your laptop or pc
Because for giving inputs through voice need microphone
Firts:
you need a microphone
Second
Check if EVERY bracket has a closing part and if it still doesn't work then start over from scratch
I am trying SpeechRecognition module but i can get it to work.
Can anyone pleas help me.
I am using Linux Mint
Thias is my python code:
import speech_recognition as sr
r = sr.Recognizer()
try:

audio = r.listen(source)
text = r.recognize_google(audio)
print(text)
except:
print("not working")
and I get this error:

I'm setting up a sound recognizer with the speechRecognition python library.
This is my code so far:
#!/usr/bin/env python3
import speech_recognition as sr
r = sr.Recognizer('es-MX')
with sr.Microphone() as mic:
audio = r.listen(mic)
print(r.recognize(audio))
On running I get

I'm using SpeechRecognition version 1.3.1 running on Linux LXLE 14.04 x64 with python 3.4
It tells you it can not record audio on your device. It is not related to a jack server, it also tries to open alsa device and bluetooth audio device. Make sure that audio is properly set on your device. See also
PyAudio does not work and bricks sound on ubuntu
PyAudio working, but spits out error messages each time
I am having this same error. If you would like a work around you can use my code I wrote. I used the sounddevice library to record audio while there is audio it saves into one file, then convert it to text using the speech recognition library. The error comes when microphone is called in as it is using PyAudio.
https://shepai.github.io/code/PetSHEP/soundLib.py
The following lines should replace your "with microphone" bit
with sr.AudioFile(filename) as source:
Audio=r.record(source)
This is how I got round the problem, hope it helps :)
