not found output as speech to text

[akshat9425]

i used your provided transcribe function for speech to text and i replaced your provided _decoder with other objects provided by pocketsphinx here is my code

def transcribe(fp):

config = pocketsphinx.Decoder.default_config()
config.set_string('-hmm', HMDIR)

config.set_string('-lm', LMDIR)
config.set_string('-dict', DICTD) 
decoder = Decoder(config)

speech_rec = pocketsphinx.Decoder(config)
opened_file =  open(fp)
print("\n""types results",type(opened_file),"\n\n")
#exit(0)
opened_file.seek(44)

    # FIXME: Can't use the Decoder.decode_raw() here, because
    # pocketsphinx segfaults with tempfile.SpooledTemporaryFile()
data = opened_file.read()
decoder.start_utt()
decoder.process_raw(data, False, True)
decoder.end_utt()

result = decoder.hyp()

result = speech_rec.get_hyp()

exit(0)

print("our results",result)
transcribed = [result]
logging.info('PocketSphinx ?????%r', transcribed)
return transcribed 

and i got this as output 👍

You just said: <pocketsphinx.pocketsphinx.Hypothesis; proxy of <Swig Object of type 'Hypothesis *' at 0x7f074c6033f0> >

but expecting speech to text

someone please suggest what's wrong here

and if i use

decoder.hyp().hypstr

than nothing is printed as output

where did you get this code ?
what version of pocketsphinx are you using ?

[akshat9425]

Thanks for reply let me explain from scratch
I used https://github.com/VikParuchuri/scribe but in above repo there is a file named recognizer.py which contains function recognize() inside that there is decode_raw() which is not supported now

for its replacement i use algorithm of EXAMPLE 46 of this link
https://www.programcreek.com/python/example/10479/tempfile.SpooledTemporaryFile

here is my code of that function

def transcribe(fp):

config = pocketsphinx.Decoder.default_config()
config.set_string('-hmm', HMDIR)
config.set_string('-lm', LMDIR)
config.set_string('-dict', DICTD) 
decoder = Decoder(config)

speech_rec = pocketsphinx.Decoder(config)
opened_file =  open(fp)
print("\n""types results",type(opened_file),"\n\n")

opened_file.seek(44)
data = opened_file.read()
print("value of data",data)
decoder.start_utt()
decoder.process_raw(data, False, True)
print("value of process_raw",decoder.process_raw(data, False, True))
decoder.end_utt()

result = decoder.hyp().hypstr

print("our results",result)
transcribed = [result]
logging.info('PocketSphinx ?????%r', transcribed)
return transcribed 

version of pocketsphinx is : Version: 0.1.15
version of sphinxbase is : Version: 0.8

if i speak nothing than i got 0 as output from process_raw and if i say hello i got some specific value like 256 from process_raw() but blank string from decoder.hyp().hypstr

Download latest (5prealpha) Pocketsphinx and Sphinxbase code from github
and try followig example
https://github.com/cmusphinx/pocketsphinx/blob/master/swig/python/test/decoder_test.py

or see similar code in jasper-dev
https://github.com/jasperproject/jasper-client/blob/jasper-dev/plugins/stt/pocketsphinx-stt/sphinxplugin.py

i used https://github.com/cmusphinx/pocketsphinx/blob/master/swig/python/test/decoder_test.py
and pass my audio file with .wav extension in place of goforward.raw file and goforward.mfc file i also ran code as it is once

in all three cases i got results as: hyp().hypstr gives blank string and model score along with confidence are giving some values

what to did to get text from hyp().hypstr of wav file

[akshat9425]

i need to know while creating decoder other than .dict and .bin file you also passed a file of hmm model which one file it is i downloaded https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/US%20English/cmusphinx-en-us-8khz-5.2.tar.gz/download from here i found 6-7 files inside it

[G10DRAS]

Make sure wav file is in 16Khz 16 bit mono format.

Try this model

https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/US%20English/cmusphinx-en-us-ptm-5.2.tar.gz/download

[akshat9425]

thanks alot man its now working i was stucked from many days because of this

[akshat9425]

yeah, its working well but i need model for indian english and hindi i think that was for american english i already developed application for speech to text in american english
will you please suggest me or send links to download model for indian english and hindi that would work with pocketsphinx

[G10DRAS]

Did you search sourceforge for it ??

[akshat9425]

yeah, i found their pretrained indian english and hindi models but they are not working

[akshat9425]

https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/Indian%20English/cmusphinx-en-in-5.2.tar.gz/download

https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/Indian%20English/cmusphinx-en-in-5.2.tar.gz/download

see above two

even when you sent me 6th model from below link https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/US%20English/
us english works but first one model of this link doesn't works

[akshat9425]

while using hindi model i got below error
AttributeError: 'NoneType' object has no attribute 'hypstr'

here is my code
from os import environ, path

from pocketsphinx.pocketsphinx import *
from sphinxbase.sphinxbase import *

MODELDIR = "/home/user/scribe/model/hindi/"
DATADIR = "/home/user/scribe/pocketsphinx/test/data/"

config = Decoder.default_config()
config.set_string('-hmm', path.join(MODELDIR, 'hindi_hmm'))
config.set_string('-lm', path.join(MODELDIR, 'hindi.lm'))
config.set_string('-dict', path.join(MODELDIR, 'hindi.dic'))
config.set_string('-logfn', '/dev/null')
decoder = Decoder(config)

#stream = open(path.join(DATADIR, 'goforward.raw'), 'rb')
stream = open('/home/user/Downloads/Audio_Conversation-001.wav', 'rb')

in_speech_bf = False
decoder.start_utt()
while True:
buf = stream.read(1024)
if buf:
decoder.process_raw(buf, False, False)
if decoder.get_in_speech() != in_speech_bf:
in_speech_bf = decoder.get_in_speech()
if not in_speech_bf:
decoder.end_utt()
print 'Result:', decoder.hyp().hypstr
decoder.start_utt()
else:
break
decoder.end_utt()

If not working then Train your own model.

[akshat9425]

how?
i am a beginner please send me any suggestion to train my own model

[G10DRAS]

a good start point
