The agency said its online tool automatically strips out jargon and clichés from politicians’ speeches and statements.
The tool has an updated scoring system based on two variables.
The first is 'filler count' and adds up the number of separate pieces of 'waffle' in any one speech.
The second score, expressed as a percentage, is the ‘Switchoffeter’, which assesses how likely the listener is to drift off during the speech.
Phrases in the Polifiller database include variations on "to you I say", as well as "clean up the mess", "hard-working families" and "long-term economic plan".
Houston’s managing director, Hamish Thompson, warned politicians to find fresher ways of expressing themselves, or risk a high Polifiller score.
Thompson invited people to tweet him @HamishMThompson with suggestions for phrases to be included on the Polifiller database.
