Keywords and Categories API

The Speech Analytics Keywords and Categories API allows our clients to access Keyword and Category Speech Analytics reports through HTTP requests. The files can be received in either XML or CSV.

This report provides keywords and categories for all phone calls for a given time period.

What is a call category?

Customers and potential customers will call your business for multiple different reasons. You can use our Speech Analytics module to categorise each call into meaningful groups so you can do further analysis.

Examples of call categories include:

  • Sales Calls
  • Bookings
  • Account Enquiries
  • Membership Enquiries
  • Billing
  • Support

How do you create a call category?

During the setup phase of the Speech Analytics module, you will provide Delacon with your business’s main call categories as you know them. Each call category will have within it a set of keywords that are related to that category, plus a weighting for each keyword. This weighting defines the importance of that keyword to that category. Note that keywords can be in multiple categories.

When the module analyses the phone call, it will take the keyword and its weighting into consideration before deciding what category the call should be in.

For example, a call may feature keywords from both the sales category and the billing category but may mention sale category keywords more frequently or may mention sales category keywords which have a higher weighting than the billing keywords mentioned. Therefore, the call will be defined as a sales call.

What is a keyword?

A keyword is the word or phrase you are looking for in each call category. Each keyword will have a weighting to define their level of importance to each category.

We can also use keyword spotting where our module looks for specific keywords which may be separate to your category keywords. For example, if you are running a promotion for a specific product, you can keyword spot to see how often this product is mentioned in phone calls.
