CALCULATE YOUR SPEAKER POLLUTION INDEX
What is the Speaker Pollution Index (SPI) in your audio presentations?
 
Let's lay the ground work for a comparison.
Start with an organization's visual representations, such as a logo. Companies spend thousands of dollars creating a good looking logo that is clean and crisp.
When it comes to audio presentations, more often than not, there is little or no concern given to clean and crisp audio. Even a big company like Citrix, which wants companies to use its services for webinars, fails to mention in its promotional material that clean delivery is a desirable quality in a speaker. (See 11 Tips for Webinar Speakers from an Audio Editor.)
To get an idea of how well your audio representations are sounding, calculate the Speaker Pollution Index.
Count the number of audible pollutions in a presentation. Audible pollutions can include, but are not limited to:
  • Um
  • Uh
  • Ah
  • You Know
  • Right
  • any unique utterances from the speaker that do not add meaning or content to the presentation.
 
In one recorded interview between interviewer and guest, the Speaker Pollution Index was 13.6. This was determined by 750 utterances in a 55-minute interview. 750/55 = 13.6 per minute!
The SPI could also be calculated with a 5 or 15 minute sample.
By creating Speaker Pollution Indexes, it is possible to track progress in live presentations to show improvement.
The goal, of course, is to approach an SPI of zero: 0/15. The closer to zero, the better.
A clean audio presentation is yet another organizational representation that will come into sync with a clean logo.
