Alsa lib error while running program and it automatically set particular threshold value always #100

Closed santhoshrsk closed 7 years ago

santhoshrsk commented 8 years ago

Steps to reproduce

Initially when i was working with this program in my raspberry pi running jessie, everything went so fine. But from today morning it is not picking any audio from usb microphone and always setting threshold values as 48.5477227879 even high noise and low noise situation.

so i tried to reinstall program again, eventhough it didnt worked for me.

after running main.py program it shows

"a moment of silence please.. Set minimum threshold to 48.5477227879 say something! "

thats it, after this nothing is happening.

After some time i tried to run it through terminal, it shiows error as " ALSA lib pcm_dmix.c :1022:(snd_pcm_dmix_open) unable to open slave" say some thing

what shall i do now to make this program run.

Expected behaviour

Run program without error and recognise speech.

Actual behaviour

scenario 1: Running from python

program running , no error, it shows "a moment of silence please.. Set minimum threshold to 48.5477227879 say something! "

and stay like this for whole time.

scenario 2: Running from terminal

"ALSA lib pcm_dmix.c :1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm rear ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm center_lfe ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm side ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm hdmi ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm hdmi ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm modem ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm modem ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm phoneline ALSA lib pcm.c:2289:(snd_pcm_open_noupdate) unknown PCM cards.pcm phoneline ALSA lib pcm_dmix.c :1022:(snd_pcm_dmix_open) unable to open slave Say something"

and stay like this at all, no more recognition.

System information

My SpeechRecognition library version is <3.3.3>.

My PyAudio library version is <0.2.9>

I installed PocketSphinx from Debian repositories.

Hi, I rectified this problem by reflashing my raspberry pi with new os and started again from scratch. But program works fine with my webcam microphone and when i change it to usb microphone it shows " IOError: -9997 Invalid sample rate"

to check sample rate, i gave sample rate as 44100 in Microphone declaration part in _main.py , then it is working but it is very slow, what to do now?

Uberi commented 8 years ago

Hi @santhoshrsk,

Can you run python -c "import pyaudio;audio=pyaudio.PyAudio();print([audio.get_device_info_by_index(i) for i in range(audio.get_device_count())])", and then paste the result here?

Also, try setting chunk_size to a larger value, like Microphone(chunk_size=8192), and see if that makes things a bit faster.

Hi, I'm having problems with ALSA when I run the library, I'm using Ubuntu 16.04 LTS (4.4.0-22-generic).

I've also tried changing the chunk_size value to 8192 and the problem persist.

Thanks in advance! NB

Hi @nbulian,

For some reason, it seems like you have a device on index 1, but not index 0. You can get around this by using Microphone(device_index=1) instead of Microphone() in your code.

nbulian commented 8 years ago

Hi @Uberi Thanks for your response! I did what you propose, but the problem with ALSA persist, but at least in another line!

Any way, thanks for your awesome work and your help.

@nbulian, can you post the code you're using, verbatim?

nbulian commented 8 years ago

This is the code I'm using:

import speech_recognition import pyttsx

speech_engine = pyttsx.init('espeak') speech_engine.setProperty('rate', 150)

def speak(text): speech_engine.say(text) speech_engine.runAndWait()

recognizer = speech_recognition.Recognizer()

def listen(): with speech_recognition.Microphone() as source: recognizer.adjust_for_ambient_noise(source) audio = recognizer.listen(source)

try: return recognizer.recognize_sphinx(audio) except speech_recognition.UnknownValueError: print("Could not understand audio") except speech_recognition.RequestError as e: print("Recog Error; {0}".format(e))

return ""

speak("Say something!") speak("I heard you say " + listen())

Uberi commented 8 years ago

@santhoshrsk, which part is slow, specifically?

@nbulian, actually, device_index=0 is correct, not device_index=1 as I said originally. Does this work for you? Also, there seems to be something wrong with your ALSA configuration; can you use arecord to obtain microphone recordings?

@hoangpx, try Microphone(device_index=2) - notice that the entry at index 2 is your actual USB sound card.

santhoshrsk commented 8 years ago

@Uberi ,When i use usb microphone, it is working only sample rate 44100 and i increased chunk size also to max of 8192 and when i speak it takes minimum 1 to 3 minutes to recognise and analyse takes some more time ,final result is taking about 5 to 7 minutes every time,even for a single word.

AlexMcDermott commented 8 years ago

I am having the same problem. Even when I specify device_index=2 when creating a microphone object I still get the errors. I have tried numerous things such as changing the device index manually which didn't work. It works with arecord but that's it. If you want them I can post the errors.

Uberi commented 8 years ago

It seems like things worked out for @hoangpx and @nbulian in this thread, so:

@manishsharma1992, try Microphone(sample_rate=44100) - your microphone's default sample rate seems to be 44.1 kHz.
@AlexMcDermott, it would be very helpful to have the information requested in this post, as well as your code.

Hi, great work @Uberi . I would like to bring in your notice that it worked perfectly when i initially tested examples but later i got same problem.

Hi @jatinkatyal ,

I am getting the same error as you posted. Were you able to narrow down the issue?

I am testing the microphone example with sphinx: pyaudio

Any help would be appreciated! Thank you.

Uberi commented 7 years ago

Hi @soumya-gk, @jatinkatyal,

We now have a new troubleshooting entry, https://github.com/Uberi/speech_recognition#the-recognizer-hangs-on-recognizer_instancelisten-specifically-when-its-calling-microphonemicrophonestreamread, which may be a solution for that issue. Give that a try!

soumyagk commented 7 years ago

Thank you @Uberi . I tried with different device indices and although that does not remove the error messages - the recognition worked. Currently it is working without providing any index too.

Hi @Bobbyissad,

Did you try to troubleshooting advice? Does it work when you select the correct device index?

SimeonAleksov commented 7 years ago

Hi @Uberi , I'm having the same problem, I tried every index, it doesn't seem to work, could it be because I'm using built-in microphone on laptop or it doesn't matter?

@SimeonAleksov, @alex-sch-acc, the microphone being internal should not matter, but it's strange that it's not showing up in the PyAudio devices list. Can you post the output of the debugging instructions in a new issue?

@harsh8398, I'd be happy to take a look in a new issue. For now, I'm closing this one since the original problem seems to have been resolved.

@Uberi please can you help me or any one here is my code import speech_recognition as sr import pyaudio

r = sr.Recognizer()

with sr.Microphone() as source: print('say something') audio = r.listen(source) voice_data = r.recognize_google(audio) print(voice_data)

and i get this output

matanox commented 4 years ago

Seems like an ALSA installation/configuration problem not specific to this particular project. I don't have the solution yet.

You are using which editor...??

Luban6887 commented 3 years ago

first you must know your threshold !! to find out threshold type in terminal

$python3 -m speech_recognition

then you will get a result - "Set minimum energy threshold to 1567.0664869865125" now copy the threshold then add this to your program like as

listener = sr.Recognizer()
listener.energy_threshold = 1568 
listener.dynamic_energy_threshold = True

this way i solved my problem ! now its working

waldisio commented 3 years ago

Yeah! It works here. Thank-you, Luban6887 !
