  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Video files conversion/transcoding Google App Engine

    15 août 2013, par Vasilis

    I want to start a cloud computing project with the simple task to :

    1. Receive uploaded video files
    2. Do some transcoding / converting to them
    3. Allow user to download / stream the generated file

    I was thinking ffmpeg as an external command line tool integrated in a Java/Google App engine Application. Since it was fairly hard to be assured about the limitations of the framework, can someone tell me if this is feasible ?

    Thank you in advance !

  • Improving Google Cloud Speech-to-Text accuracy

    6 juillet 2020, par lr_optim

    I'm working on a project where I need to perform these steps :

    


      

    1. Record a voice call (.webm -file)

      2. 


    2. Split the webm -file into chunks with ffmpeg and convert the file into wav

      3. 


    3. Transcribe the chunks using SpeechRecognition -library and Google Cloud API

      4. 


    


    I've faced problems with the transcription accuracy and wondering if there is something I could do to improve it. At the time I'm splitting the original file into 30s chunks. I thought there might be one problem, that I might be missing words because of splitting so I've tried also with longer chunks under 60s but didn't notice any improve in accuracy.
Reading trough the speechRecognition docs I decided to set r.energy_threshold = 4000, I also tried to set the energy_treshold dynamically like this :

    


    with sr.AudioFile(name) as source:
    r.dynamic_energy_threshold = True
    r.adjust_for_ambient_noise(source, duration = 1)
    audio = r.record(source)


    


    I've also tested en-US and en-GB to see if there's some difference but there isn't as much as I'd want. The program is supposed to work with english language spoken by nordic people. If someone has experience about choosing a right language model for people speaking with accent, please let me know.

    


    This is the ffmpeg command is use to split the webm file into chunks : command = ['ffmpeg', '-i', filename, '-f', 'segment', '-segment_time', '30', parts_dir + outputname + '%09d.wav']

    


    Is there somethig I could do better ? I'm wondering if the quality is not good enough an Google is having hard time because of that ?

    


    The main problem is I'm getting bad results (lots of wrong words) from Google and wondering if there is something I could do about it.
