inaSpeechSegmenter

inaSpeechSegmenter is a CNN-based audio segmentation toolkit.

It splits audio signals into homogeneous zones of music and speech. 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 are tagged as speech.

inaSpeechSegmenter has been designed in order to perform large-scale gender equality studies based on men and women speech-time percentage estimation.

Installation

inaSpeechSegmenter is a framework in python 3. It can be installed using the following procedure:

Prerequisites

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

PIP installation

Simplest installation procedure

# create a python 3 virtual environement and activate it
$ virtualenv -p python3 inaSpeechSegEnv
$ source inaSpeechSegEnv/bin/activate
# install a backend for keras (tensorflow, theano, cntk...)
$ pip install tensorflow-gpu # if you wish GPU implementation (recommended if your host has a GPU)
$ pip install tensorflow # for a CPU implementation
# install framework and dependencies
$ pip install inaSpeechSegmenter

Installing from from sources

# clone git repository
$ git clone https://github.com/ina-foss/inaSpeechSegmenter.git
# create a python 3 virtual environement and activate it
$ virtualenv -p python3 inaSpeechSegEnv
$ source inaSpeechSegEnv/bin/activate
# install a backend for keras (tensorflow, theano, cntk...)
$ pip install tensorflow-gpu # if you wish GPU implementation (recommended)
$ pip install tensorflow # for a CPU implementation
# install framework and dependencies
$ cd inaSpeechSegmenter
$ python setup.py install

Using inaSpeechSegmenter

Speech Segmentation Program

Binary program ina_speech_segmenter.py may be used to segment multimedia archives encoded in any format supported by ffmpeg. It requires input media and output csv files corresponding to the segmentation. Corresponding csv may be visualised using softwares such as https://www.sonicvisualiser.org/

# get help
$ ina_speech_segmenter.py --help
usage: ina_speech_segmenter.py [-h] -i INPUT [INPUT ...] -o OUTPUT_DIRECTORY

Does Speech/Music and Male/Female segmentation. Stores segmentations into CSV
files

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT [INPUT ...], --input INPUT [INPUT ...]
                        Input media to analyse. May be a full path to a media
                        (/home/david/test.mp3), a list of full paths
                        (/home/david/test.mp3 /tmp/mymedia.avi), or a regex
                        input pattern ("/home/david/myaudiobooks/*.mp3")
  -o OUTPUT_DIRECTORY, --output_directory OUTPUT_DIRECTORY
                        Directory used to store segmentations. Resulting
                        segmentations have same base name as the corresponding
                        input media, with csv extension. Ex: mymedia.MPG will
                        result in mymedia.csv

Using Speech Segmentation API

InaSpeechSegmentation API is intended to be very simple to use. See the following notebook for a comprehensive example: API Tutorial Here!
