Data Types for Conversation Analytics

Conversation analytics is work done to undertand, monitor, and track information within speech or text from conversations. This is powerful within sales, service, and media. We use conversation analytics to determine topic, sentiment, intent, and compliance to drive conversion, quality, and efficiency.

Here we demonstrate a few types data types that are useful for capturing and modeling the speech conversation data type so it is analytics ready. These examples can be found on github at


Switchboard is one data type where it captures speaker phrases as they go back and fourth. More details can be found at []

The python description says: A specialized list object used to encode switchboard utterances. The elements of the list are the words in the utterance; and two attributes, speaker and id, are provided to retrieve the spearker identifier and utterance id. Note that utterance ids are only unique within a given discourse.

Here is a sample of python code to load the sample data:

import nltk
from nltk.corpus import switchboard

Here is the sample data:

[<B.2: u'Uh , yeah , currently we have a poodle .'>,
 <A.3: u'A poodle , miniature or , uh , full size ?'>,
 <B.4: u"Yeah , uh , it 's , uh miniature .">,
 <A.5: u'Uh-huh .'>,
 <B.6: u'Yeah .'>,
 <A.7: u'I read somewhere that , the poodles is one of the , the most intelligent dogs , uh , around .'>,
