Coherence Algorithm

Coherence Algorithm used in Automated analysis of free speech predicts psychosis onset in high-risk youths (download the paper) to study the speech coherence level. For now, the algorithm works in English but it is very easy to adapt into others languages.

On-line use

It is available to use online in the site: http://speech-tools.liaa.dc.uba.ar/coherence/

Install

The easy way to install is using pip, doing:

pip install git+https://github.com/facuzeta/coherence/

It takes some time becouse it has to download the trained models ( more than > 30 MB)

Example

After install...

import coherence

some_large_text= "The campaign brought ... I began by making up my mind..."

coh = coherence.coherenceAnalisys()
res = coh.analysis_text(some_large_text) 

res is the dictionary with the statistics, you can see the result using the on-line app http://speech-tools.liaa.dc.uba.ar/coherence/

How does it work?
