PronSci charts

The set of PronSci charts is made up of a Rectangle chart, a two-part Spelling chart (also known as a Fidel), and 16 Word charts. The charts are shown in full below.

 

Other pages show supplementary teaching materials, have information about chart sizes, prices and training, and show the Silent Way word charts for English and Spanish.

 

 

The PronSci Rectangle chart is organised along articulatory lines. Each coloured rectangle represents a sound of English. (The key to the layouts can be found below the pictures.)

This document includes black and white versions of the charts with IPA symbols (as below), in a size for self-study and a larger size for the classroom wall. These can be freely reproduced.

 

You can see a video describing the reasons for the layout here.

In the arrangement of the sounds on the charts, note that:

  1. The vowels, as well as the consonants, are organised by the movements needed to produce them.
  2. The vowels are presented as either high or low energy, at the top and bottom of the chart respectively. This clearly differentiates the 'normal' vowels from schwa and the other reduced vowels.
  3. The consonants, in the middle section, are arranged by place and manner of production as conventionally done. But their grouping also reflects the distinctive articulatory setting of English.

The Spelling chart (Fidel) shows the complete relationship between sounds and spelling in English. Its overall organisation is the same as that of the rectangle chart, so sounds appear in the same colour and in the same location on each.

 

One of the advantages of using colour for sounds rather than using IPA symbols, is that words can be written normally, but with their pronunciation apparent at the same time.

 

Any word in English (except for unusual proper names) can be spelled out using the groups of letters on the Fidel, with the word's correct pronunciation indicated by the colours chosen. Letters and letter combinations that are part of the underlying spelling system are printed in a larger size than those that are needed for just a few words.

A full key is provided with the Fidel, with example words for each spelling and information about phonetic symbols etc.

The sixteen Word Charts contain the functional vocabulary of English organised by parts of speech. The charts use the same colours as the Rectangle chart and the Spelling chart to indicate the pronunciation of words. The strong and weak forms of those words which have two pronunciations are shown by the dots beneath them.

 

As well as individual words, whole sentences can be pointed out. This enables students to work on the production of natural speech without having to follow a teacher’s model.
