inaSpeechSegmenter is a CNN-based audio segmentation toolkit suited to the tasks of Voice Activity Detection and Speaker Gender Segmentation.
It splits audio signals into homogeneous zones of speech, music and noise. Speech zones are split into segments tagged using speaker gender (male or female). Male and female classification models are optimized for French language since they were trained using French speakers (accoustic correlates of speaker gender are language dependent). Zones corresponding to speech over music or speech over noise are tagged as speech. Singing voice is tagged as music.
- 🏆 ranked #1 against 6 open-source VAD system on a French TV and radio benchmark
- 🏳️⚧️ Extended as a non-binary Voice Gender Prediction system for evaluating Transgender voice transition
- 😎 Used since 2020 in the annual French Audivisual Regulation Authority report on women representation in TV and radio!
- 🌟 Used to investigate the relationship between manual and automatic women representation descriptors in French TV and radio
- ♀️ ♂️ Applied for large-scale gender representation studies in French TV and radio.
- 🥳 Won MIREX 2018 speech detection challenge.
inaSpeechSegmenter works with Python 3.7 to Python 3.12. It is based on Tensorflow which does not yet support Python 3.13+.
It is available on Python Package Index inaSpeechSegmenter and packaged as a docker image inafoss/inaspeechsegmenter.
inaSpeechSegmenter requires ffmpeg for decoding any type of format. Installation of ffmpeg for ubuntu can be done using the following commandline:
$ sudo apt-get install ffmpeg# create a python 3 virtual environement and activate it
$ virtualenv -p python3 env
$ source env/bin/activate
# install framework and dependencies
$ pip install inaSpeechSegmenter# clone git repository
$ git clone https://github.com/ina-foss/inaSpeechSegmenter.git
# create a python 3 virtual environement and activate it
$ virtualenv -p python3 env
$ source env/bin/activate
# install framework and dependencies
# you should use pip instead of setup.py for installing from source
$ cd inaSpeechSegmenter
$ pip install .
# check program behavior
$ python setup.py testBinary program ina_speech_segmenter.py may be used to segment multimedia archives encoded in any format supported by ffmpeg. It requires input media and provide 2 segmentation output formats : csv (can be displayed with Sonic Visualiser) and TextGrid (Praat format). Detailed command line options can be obtained using the following command :
# get help
$ ina_speech_segmenter.py --helpInaSpeechSegmentation API is intended to be very simple to use, and is illustrated by these 2 notebooks :
- Google colab tutorial: use API online
- Jupyter notebook tutorial : to be used offline
The class allowing to perform segmentations is called Segmenter. It is the only class that you need to import in a program. Class constructor accept 3 optional arguments:
- vad_engine (default: 'smn'). Allows to choose between 2 voice activity detection engines.
- 'smn' is the more recent engine and splits signal into speech, music and noise segments
- 'sm' was not trained with noise examples, and split signal into speech and music segments. Noise segments are either considered as speech or music. This engine was used in ICASSP study, and won MIREX 2018 speech detection challenge.
- detect_gender (default: True): if set to True, performs gender segmentation on speech segment and outputs labels 'female' or 'male'. Otherwise, outputs labels 'speech' (faster).
- ffmpeg: allows to provide a specific binary of ffmpeg instead of default system installation
